➜  desktop ccat pp.py
import requests

def download(url):
        r = requests.get(url)
        with open("res.txt", 'w', encoding='utf-8') as f:
                f.write(r.text)

def main():
        url = input("Enter your url here... ")
        download(url)

if __name__ == '__main__':
        main()

为什么会有这样的问题？

楼上找不到编译器的。
