在PY学习过程中 第三方库的安装是必不可少的一步骤 但是从一个新环境一步步安装第三方库很麻烦 可以采用以下方法快速安装第三方库

import os
libs={"numpy","matplotlib","pillow","sklearn","requests",\
      "jieba","beautifulsoup4","wheel","networkx","sympy",\
      "pyinstaller","django","flask","werobot","pyqt5",\
      "pandas","pyopengl","pypdf2","docopt","pygame"}
      

try:
    os.system("python -m pip install --upgrade pip -i https://pypi.tuna.tsinghua.edu.cn/simple")
    print("Update Successful")
except:
    print("Failed")
    
try:
    for lib in libs:
        os.system("pip install " + lib +" -i https://pypi.tuna.tsinghua.edu.cn/simple")
    print("Successful")
except:
    print("Failed")
os.system("pause")

在以上代码中 :

1.  libs 字段中填写第三方库名 

2.  强制更改源为清华大学源 增加国内下载速度

3.  自动更新pip版本为最新 防止第三方库文件安装失败 

4.  安装后 若出现Successful 需要敲击键盘确认 则代表安装成功
