I was in this article ：python 180000 word tutorial I've already said , But many fans ignore , Maybe I write too much , You didn't notice . Let me talk about it again .
Maybe you like it when you study copy Other people's code , When running, the opportunity appears ：
No module named xxx
It means that a module is missing . So we need to install modules .
terminal perform ：
pip install xxx
Suppose we are No module named requests,teiminal perform ：
pip install requests
