Write a python function called 'mtv_to_sf(str) -> dict' that will take a timetable like the following as a string as input, and return how long it takes the 703, 303, and 509 trains to get from Mountain View to San Francisco in minutes? Return a dictionary {"703": time in minutes, "303": ..., "509": ...}. The timetable may change over time so write the function to look at the new data I have in the future.

To solve this problem, we need to parse the given timetable and extract the departure and arrival times for the specified trains (703, 303, and 509) from Mountain View to San Francisco. Then, we will calculate the travel times in minutes and return the results in a dictionary. Here's a step-by-step breakdown of the approach: 1. **Parse the timetable**: The timetable is provided as a string, so we need to split it into lines and then further split each line into individual elements. 2. **Identify the relevant columns**: We need to locate the columns for Mountain View and San Francisco stations, as well as the columns for the specified trains (703, 303, and 509). 3. **Extract and convert times**: Extract the departure times from Mountain View and the arrival times at San Francisco for the specified trains. Convert these times from the 12-hour format to minutes. 4. **Calculate travel times**: Compute the travel times in minutes between Mountain View and San Francisco for each specified train. 5. **Return the results**: Format the results in a dictionary as specified. Here is the Python function that implements this approach:

from datetime import datetime

def convert_to_minutes(time_str):
    dt = datetime.strptime(time_str, '%I:%M%p')
    return dt.hour * 60 + dt.minute

def mtv_to_sf(timetable):
    lines = timetable.strip().split('\n')
    headers = lines[0].split()
    station_lines = lines[3:]  # Skipping the first 3 lines (Station Name, Zone, Service Type)
    
    train_indices = {train: headers.index(train) for train in ["703", "303", "509"]}
    mtv_index = headers.index("Mountain View")
    sf_index = headers.index("San Francisco")
    
    train_times = {}
    
    for train, train_idx in train_indices.items():
        mtv_time_str = None
        sf_time_str = None
        
        for line in station_lines:
            parts = line.split()
            if parts[0] == "Mountain":
                mtv_time_str = parts[train_idx]
            elif parts[0] == "San" and parts[1] == "Francisco":
                sf_time_str = parts[train_idx]
            
            if mtv_time_str and sf_time_str:
                break
        
        if mtv_time_str == "--" or sf_time_str == "--":
            train_times[train] = None
        else:
            mtv_time = convert_to_minutes(mtv_time_str)
            sf_time = convert_to_minutes(sf_time_str)
            travel_time = sf_time - mtv_time
            train_times[train] = travel_time
    
    return train_times

Extract Code

I extracted the following code from that output:

    dt = datetime.strptime(time_str, '%I:%M%p')
    return dt.hour * 60 + dt.minute

    lines = timetable.strip().split('\n')
    headers = lines[0].split()
    station_lines = lines[3:]  # Skipping the first 3 lines (Station Name, Zone, Service Type)
    
    train_indices = {train: headers.index(train) for train in ["703", "303", "509"]}
    mtv_index = headers.index("Mountain View")
    sf_index = headers.index("San Francisco")
    
    train_times = {}

To solve this problem, we need to parse the timetable for the specified train numbers (703, 303, and 509) and calculate the travel time from Mountain View to San Francisco. Here is a function that does just that:

def mtv_to_sf(timetable: str) -> dict:
    import re
    from datetime import datetime

    # Split the timetable into lines
    lines = timetable.strip().split('\n')

    # Extract the station names from the first line
    station_names = lines[0].split()[2:]  # Skip the first two columns (Station Name and Zone Service Type)

    # Extract the time columns for the relevant trains
    train_times = {train: [] for train in ["703", "303", "509"]}

    for line in lines[1:]:
        parts = line.split()
        station = parts[0]
        times = parts[2:]  # Skip the first two columns

        if station == "Mountain View":
            for train in train_times:
                try:
                    train_index = station_names.index(train)
                    train_times[train].append(times[train_index])
                except ValueError:
                    pass

        elif station == "San Francisco":
            for train in train_times:
                try:
                    train_index = station_names.index(train)
                    train_times[train].append(times[train_index])
                except ValueError:
                    pass

    # Function to convert time string to minutes since start of the day
    def time_to_minutes(time_str):
        if time_str == "--":
            return None
        time = datetime.strptime(time_str, "%I:%M%p")
        return time.hour * 60 + time.minute

    # Calculate the travel times
    travel_times = {}
    for train in train_times:
        mtv_time = time_to_minutes(train_times[train][0])
        sf_time = time_to_minutes(train_times[train][1])
        if mtv_time is not None and sf_time is not None:
            travel_times[train] = sf_time - mtv_time

    return travel_times

Output

To solve this problem, we need to parse the timetable, extract the times for the specific trains (703, 303, and 509) at the Mountain View and San Francisco stations, calculate the difference in minutes between these times, and return the results in a dictionary. Here's a step-by-step approach to achieve this: 1. Parse the timetable string to extract the relevant columns and rows. 2. Find the times for the 703, 303, and 509 trains at the Mountain View and San Francisco stations. 3. Calculate the travel time in minutes for each train. 4. Return the results in a dictionary. Below is the Python function implementing the described approach:

from datetime import datetime

def mtv_to_sf(timetable: str) -> dict:
    # Split the timetable string by lines
    lines = timetable.strip().split("\n")
    
    # Extract the header (station names and train numbers)
    header = lines[0].split()
    train_numbers = header[2:]  # Train numbers start from the 3rd column

    # Find the indices of Mountain View and San Francisco stations
    station_indices = {station: idx for idx, station in enumerate(header) if station in ["Mountain View", "San Francisco"]}

    # Initialize a dictionary to store the times for the specified trains
    times = {"703": {"Mountain View": None, "San Francisco": None},
             "303": {"Mountain View": None, "San Francisco": None},
             "509": {"Mountain View": None, "San Francisco": None}}

    # Iterate over each line to find the times for specified trains
    for line in lines:
        parts = line.split()
        if parts[0] in ["Mountain View", "San Francisco"]:
            station = parts[0]
            for train in times.keys():
                try:
                    train_idx = train_numbers.index(train) + 2  # Adjust index to match the column in the line
                    times[train][station] = parts[train_idx]
                except ValueError:
                    pass

    # Function to convert time string to minutes since midnight
    def time_to_minutes(time_str):
        if time_str is None or time_str == '--':
            return None
        time_obj = datetime.strptime(time_str, "%I:%M%p")
        return time_obj.hour * 60 + time_obj.minute

    # Calculate travel times in minutes
    travel_times = {}
    for train, stations in times.items():
        mtv_time = time_to_minutes(stations["Mountain View"])
        sf_time = time_to_minutes(stations["San Francisco"])
        if mtv_time is not None and sf_time is not None:
            travel_times[train] = sf_time - mtv_time

    return travel_times

Output

To extract the travel times from the provided timetable, we need to parse the timetable string and extract the times for the specific trains (703, 303, and 509) from Mountain View to San Francisco. Here's a Python function to accomplish this:

def mtv_to_sf(timetable: str) -> dict:
    from datetime import datetime

    # Split the timetable into lines
    lines = timetable.split('\n')

    # Extract the header line and the Mountain View and San Francisco lines
    header = lines[0].split()
    mtv_line = [line for line in lines if "Mountain View" in line][0].split()
    sf_line = [line for line in lines if "San Francisco" in line][0].split()

    # Extract the times for the specified trains
    train_numbers = ["703", "303", "509"]
    mtv_times = {train: None for train in train_numbers}
    sf_times = {train: None for train in train_numbers}

    for i, station in enumerate(header):
        if station in train_numbers:
            mtv_times[station] = mtv_line[i]
            sf_times[station] = sf_line[i]

    # Calculate the travel times in minutes
    travel_times = {}
    for train in train_numbers:
        if mtv_times[train] != '--' and sf_times[train] != '--':
            mtv_time = datetime.strptime(mtv_times[train], '%I:%M%p')
            sf_time = datetime.strptime(sf_times[train], '%I:%M%p')
            travel_time = int((sf_time - mtv_time).total_seconds() / 60)
            travel_times[train] = travel_time
        else:
            travel_times[train] = None

    return travel_times

To solve the problem of calculating the travel time in minutes for trains 703, 303, and 509 from Mountain View to San Francisco, we need to parse the timetable string, extract the relevant times, and compute the differences. Here's a Python function to do that:

from datetime import datetime

def parse_time(time_str):
    """Parse time string into a datetime object."""
    try:
        return datetime.strptime(time_str, "%I:%M%p")
    except ValueError:
        return None

def calculate_travel_time(start_time_str, end_time_str):
    """Calculate the difference in minutes between two time strings."""
    start_time = parse_time(start_time_str)
    end_time = parse_time(end_time_str)
    if start_time and end_time:
        travel_time = (end_time - start_time).seconds // 60
        return travel_time
    return None

def mtv_to_sf(timetable: str) -> dict:
    # Split the timetable into lines
    lines = timetable.split("\n")
    
    # Extract the relevant lines for Mountain View and San Francisco
    headers = lines[0].split()
    mountain_view_times = lines[16].split()
    san_francisco_times = lines[37].split()
    
    # Initialize the dictionary to store travel times
    travel_times = {}
    
    # List of train numbers we are interested in
    train_numbers = ["703", "303", "509"]
    
    for train_number in train_numbers:
        if train_number in headers:
            index = headers.index(train_number)
            start_time = mountain_view_times[index]
            end_time = san_francisco_times[index]
            travel_time = calculate_travel_time(start_time, end_time)
            if travel_time is not None:
                travel_times[train_number] = travel_time
    
    return travel_times

# Example usage
