## 环境
```bash
root@pts/1 $ cat /etc/redhat-release
CentOS Linux release 7.1.1503 (Core)

root@pts/1 $ python -V
Python 2.7.5

## Tkinter VS tkinter
根据Python介绍发现 在Python2 和Python3 中该包名称是不一样的，在 `python2`中叫`Tkinter`； 在`python3`中叫`tkinter`
**Refer to**
[Tkinter — Python interface to Tcl/Tk](https://docs.python.org/2/library/tkinter.html#module-Tkinter)
Note Tkinter has been renamed to tkinter in Python 3.
The 2to3 tool will automatically adapt imports when converting your
sources to Python 3.

## Fix
**install tkinter under centoer by yum**
yum install -y tkinter
---
## Verify
```python
>>>
>>> import Tkinter
>>> import matplotlib.pyplot as plt
>>>
```
