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.
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.
To create a Python function named `dedent(str)` that maximally de-dents a given string of Python code, you can follow the approach below. This function will calculate the minimum indentation level of non-empty lines and remove that level of indentation from every line, effectively maximizing the de-indentation of the given code. Here's how you could implement it:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 | def dedent(code_str): # Split the input string into lines lines = code_str.split('\n') # Calculate the minimum indentation (excluding empty lines) min_indent = None for line in lines: stripped_line = line.lstrip() if stripped_line: # Only consider non-empty lines indent_level = len(line) - len(stripped_line) if min_indent is None or indent_level < min_indent: min_indent = indent_level # If all lines are empty or the input is empty, return the original string if min_indent is None: return code_str # De-indent each line by the minimum indentation found deindented_lines = [line[min_indent:] if len(line) >= min_indent else line for line in lines] # Re-join the lines into a single string to return return '\n'.join(deindented_lines) # Example usage: if __name__ == "__main__": code = """ def hello_world(): print("Hello, world!") if True: print("Indeed, true.") """ print(dedent(code)) |
I extracted the following code from that output:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 | def dedent(code_str): # Split the input string into lines lines = code_str.split('\n') # Calculate the minimum indentation (excluding empty lines) min_indent = None for line in lines: stripped_line = line.lstrip() if stripped_line: # Only consider non-empty lines indent_level = len(line) - len(stripped_line) if min_indent is None or indent_level < min_indent: min_indent = indent_level # If all lines are empty or the input is empty, return the original string if min_indent is None: return code_str # De-indent each line by the minimum indentation found deindented_lines = [line[min_indent:] if len(line) >= min_indent else line for line in lines] # Re-join the lines into a single string to return return '\n'.join(deindented_lines) # Example usage: if __name__ == "__main__": code = """ def hello_world(): print("Hello, world!") if True: print("Indeed, true.")

To create a Python function named `dedent` that maximally de-dents a given string of Python code, you can follow this approach. The function calculates the minimum indentation level of all non-empty lines and then removes this amount of leading space from each line. It's important to handle tabs and spaces correctly, so for simplicity, this solution will assume spaces are used for indentation. If tabs are mixed in, you might want to preprocess the string to convert tabs to spaces according to your needs. Here's a basic implementation:
