python小游戏——兔鼠大战
python小游戏——兔鼠大战
一.准备环境：更改设置pip 国内镜像
在使用pycharm来制作小游戏写代码的时候需要编译环境，使用pip镜像源，由于pip管理工具安装库文件时，默认使用国外的源文件，因此在国内的下载速度会比较慢，可能只有50KB/s。幸好，国内的一些顶级科研机构已经给我们准备好了各种镜像，下载速度可达2MB/s。所以需要更改设置成pip国内镜像。
国内源：
新版ubuntu要求使用https源，要注意。
清华：https://pypi.tuna.tsinghua.edu.cn/simple
阿里云：http://mirrors.aliyun.com/pypi/simple/
中国科技大学 https://pypi.mirrors.ustc.edu.cn/simple/
华中理工大学：http://pypi.hustunique.com/
山东理工大学：http://pypi.sdutlinux.org/
豆瓣：http://pypi.douban.com/simple/
1. 临时使用
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple some-package
可以在使用pip的时候加参数-i https://pypi.tuna.tsinghua.edu.cn/simple
例如：
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple pyspider，这样就会从清华这边的镜像去安装pyspider库。
2.默认使用
windows系统使用cmd（命令指示符）快速设置
- pip install pip -U # 升级pip到最新版本
- pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple
注：在命令指示符里依次敲以上代码，以上例子都是用的清华大学的镜像
二.进行代码的编写
# -*-conding: utf-8 -*-
#如果要在python2的py文件里面写中文，则必须要添加一行声明文件编码的注释，否则python2会默认使用ASCII编码。
#如果是python3及其以上的版本就可以不写第一行注释。
