Python program to remove C type single and multiple line comments

Question

Here is the code I've tried,

from re import *


commentStart = compile('/\*')
commentEnd = compile('\*/')
singleComment = compile('//')
quotes = compile('".*"')

def readComment(line):

    while(line):
        if(commentEnd.match(line)):
            return
        line = input()

line=input()

while(line):
    if(quotes.match(line)):
        print(line)
        line = input()
        continue

    elif(commentStart.match(line)):

        readComment(line)
        line=input()
        continue

    elif(singleComment.match(line)):
        line=input()
        continue

    else:
        print(line)

    line=input()

I'm able to remove the single line comments but i have problem with the multi line comments.

Sample input:

abcd
//blah
efg
/*blah
blah
blah*/
hij

My Output:

abcd
efg

Expected Output:

abcd
efg
hij

Please point out where I've made mistake. Thankyou.

This one:

commentEnd.match(line)

Should be:

commentEnd.search(line)

From the docs:

If you want to locate a match anywhere in string, use search() instead
