What exactly should the result of \s*#[^"']+$ be?

[anywo]

What would you like to share?

Code

import re
a = """
py_path = os.path.abspath(sys.argv[0])  # Absolute path of the current script  
str = '#FFFFFF'  # Color  
py_dir = os.path.dirname(py_path)  # Directory where the current script is located  
"""
pattern = '\\s*#[^"\']+$'
regex = re.compile(pattern, flags=re.MULTILINE) if isinstance(pattern, str) else pattern
print(re.sub(regex, "", a))

Expected behavior

py_path = os.path.abspath(sys.argv[0])
str = '#FFFFFF'
py_dir = os.path.dirname(py_path)

Actual behavior

py_path = os.path.abspath(sys.argv[0])
str = '#FFFFFF'

VsCode Result(Consistent with my understanding)

Js Result

Java Result
