所需输出：

#Created on Mar 11, 2017 @author: XXZ This file is to demonstrate the word frequency counter. This is a very important practical

（我想把它算作评论）

我的代码： 进口re

START_PATTERN = "'''\n"
END_PATTERN = "'''\n"

with open('counter.py') as file:
    match = False
    newfile = None
for line in file:
    if re.match(START_PATTERN, line):
        match = True
        newfile = open('my_new_file.txt', 'w')
        continue
    elif re.match(END_PATTERN, line):
        match = False
        newfile.close()
        continue
    elif match:
        newfile.write(line)
        newfile.write('\n')

这只是在文件中写入最后一条多行注释。不是全部

Answer 1

用替换\n。以下是代码：

a = '''
Created on Mar 11, 2017

@author: XXZ
This file is to demonstrate the word frequency counter. This is a very 
important practical

'''

print("#"+a.replace("\n"," "))

输出：

# Created on Mar 11, 2017  @author: XXZ This file is to demonstrate the word frequency counter. This is a very  important practical
