Pandas学习

1. 下载安装PyCharm(pycharm-community-2021.1.1.exe)

2. 创建一个默认项目，并修改main.py

https://github.com/hivsuper/pythonStudy.git

import numpy as np
import pandas as pd

def print_hi():
    # Use a breakpoint in the code line below to debug your script.
    print(pd.Series([1, 3, 5, np.nan, 6, 8]))  # Press Ctrl+F8 to toggle the breakpoint.


# Press the green button in the gutter to run the script.
if __name__ == '__main__':
    print_hi()

3. 在终端运行pip install pipenv添加Pipenv支持

4. 通过添加环境变量WORKON_HOME来修改Pipenv的默认路径(需重启操作系统使变量生效)

5. 在PyCharm中添加Python Interpreter

File --> Settings… -> Project: pythonStudy -> Python Interpreter -> Add…

6. 无法编译成功

7. 在PyCharm重新安装numpy和 pandas后成功编译
