在python 2.7中有以下代码：

import re

with open('myfile.txt', 'r+') as myfile:
    data = myfile.read()
    url = re.findall(r'[^https.+?]', data)
    urlshort = re.findall(r'[^https.+html?]', data)
    for url in data:
        myfile.write(url.replace(url, urlshort, data))
myfile.close()

输出为：

回溯（最近一次呼叫）： 文件“/pyscripts/数据.py，第9行，在 myfile.write文件(url.replace文件（url，urlshort，data）） TypeError:需要整数

如何在文件中工作？你知道吗

将re.sub与^{}一起使用

import re

s = """

print(re.sub(r'(https.*html).*', r'\1', s))

输出：

这样，您就可以将re.sub的整个结果写入您的文件，而不必尝试替换当前的方式。你知道吗
