The transform_comments function converts comments in a Python script into those usable by a C compiler. This means looking for text that begins with a hash mark (#) and replacing it with double slashes (//), which is the C single-line comment indicator. For the purpose of this exercise, we'll ignore the possibility of a hash mark embedded inside…

transform_comments.py

import re
def transform_comments(line_of_code):
result = re.sub(r"[#]+","//",line_of_code)
return result

import re
def transform_comments(line_of_code):
result = re.sub(r'###',r'//', line_of_code)
return result

print(transform_comments("### Start of program"))

Should be "## Start of program"

print(transform_comments(" number = 0 ## Initialize the variable"))

Should be " number = 0 // Initialize the variable"

print(transform_comments(" number += 1 # Increment the variable"))

Should be " number += 1 // Increment the variable"

print(transform_comments(" return(number)"))

Should be " return(number)"

just go ahead with re.sub(r'#+", r"//", line_of_code)
