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 single-line comment indicator. For the purpose of this exercise, we'll ignore the possibility of a hash mark embedded inside of a Python command, and assume that it's only used to indicate a comment. We also want to treat repetitive hash marks (##), (###), etc., as a single comment indicator, to be replaced with just (//) and not (#/) or (1/#). Fill in the parameters of the substitution method to complete this function: 4 1 import re 2 - def transform_comments (line_of_code): 3 result = re. sub (_) return result 5 6 print(transform_comments("### Start of program")) 7 # Should be "// Start of program" 8 print(transform_comments(" number = 0 ## Initialize the variable")) 9 # Should be number = 0 // Initialize the variable" 10 print(transform_comments(" number += 1 # Increment the variable")) 11 # Should be " number += 1 // Increment the variable" 12 print(transform_comments("return(nu mber)")) 13 # Should be return(number)" Run Reset
