In the first stage of learning Python, a lot of people do not know if you go to install the module, and if the import module, especially beginners zero-based junior partner even more so, and I see in the study group there are many such cases!
Today'll tell you about how to import the relevant instruction Python modules have module.
Source Installation
We are all in the CMD (command prompt) generally installed inside the third module of Python.
Pip install module (module name)
And we need to know Python modules can be found on GitHub source pypi or above, usually have downloaded a setup.py file, then we want to install is:

- Manually specify the source, after the pip with -i:
Pypi domestic mirror, there are many, such as:
- Watercress
- Ali Cloud
- China University of Science and Technology
- Tsinghua University
- Huazhong University of Science

Specifically we are looking for Baidu.
Many times when we install the module, there will be an error, such as:
error: Microsoft Visual C++ 10.0 is required (Unable to find vcvarsall.bat)
There are times when you will be prompted to install the module's pip, setuptools version is not the same, need to upgrade to the latest version will also give you tips.

In fact, these problems are particularly simple, even if you look at Baidu will be able to know the answer, but now more and more of a novice in the learning process, preferring to ask a very simple question in the group which can be asked Baidu ready answer how of how, if the group does not answer to the people inside him, but will also Tucao this group, if someone answered him, just to answer half of it, will be the questioner Tucao, I hope you do not reach out after the party.
