Query

Write a python function `dedent(str)` that takes as input a string of python code and de-dents it maximally. Lines that are entirely blank don't count.

Output

To create a Python function `dedent(str)` that removes the maximum common indentation from a string of Python code, we can follow these steps: 1. Split the input string into lines. 2. Identify the minimum indentation among non-blank lines. 3. Remove that minimum indentation from each line. 4. Join the lines back into a single string. Here's the implementation:

def dedent(code):
    # Split the code into lines
    lines = code.splitlines()
    
    # Find the minimum indentation among non-blank lines
    min_indent = None
    for line in lines:
        stripped_line = line.lstrip()
        if stripped_line:  # Skip blank lines
            indent = len(line) - len(stripped_line)
            if min_indent is None or indent < min_indent:
                min_indent = indent
    
    # If all lines are blank, return the original code
    if min_indent is None:
        return code
    
    # Remove the minimum indentation from each line
    dedented_lines = []
    for line in lines:
        if line.strip():  # Non-blank line
            dedented_lines.append(line[min_indent:])
        else:  # Blank line
            dedented_lines.append(line)
    
    # Join the lines back into a single string
    return '\n'.join(dedented_lines)

# Example usage:
code = """
    def foo():
        print("Hello, World!")
        
    def bar():
        print("Goodbye, World!")
"""

print(dedent(code))
### Explanation: 1. **Splitting the Code**: The input string is split into individual lines using `splitlines()`. 2. **Finding Minimum Indentation**: We iterate through the lines, skipping blank lines, and calculate the indentation of each line. The minimum indentation is stored in `min_indent`. 3. **Removing Indentation**: For each line, if it's not blank, we remove the `min_indent` number of characters from the beginning. Blank lines are left unchanged. 4. **Joining Lines**: The dedented lines are joined back into a single string with newline characters. ### Example Output: For the given example, the output will be: 
1
2
3
4
5
def foo():
    print("Hello, World!")
    
def bar():
    print("Goodbye, World!")
This function ensures that the code is dedented maximally while preserving blank lines.
