使用 python 删除 C 程序文件中的注释后获取新行

Question

1st code

2nd code

copy = open("output.txt", "w")
with open('code.txt',"r") as f:
   for line in f:
     line = line.split('/',1 )[0]
     copy.write(line)
copy=open("output.txt","r")
print(copy.read())

here it removes a comment by deleting the separate line where the comment is deleted. I want to keep a new line space where the comment was deleted in the C program.

Answer 1

import re

with open('code.txt', 'r') as f:
    lines = f.read()
    newlines = re.sub(r'/\*.*\*/', '\n', lines, flags=re.DOTALL)

with open('output.txt', 'w') as f:
    f.write(newlines)

re.DOTALL allows you to capture a pattern across lines
