# Python
I had create an python3.7 environment named pyth7(if do not have any ,see 創建環境 to build one),you can use Terminal to download package

First activate the environment ,
Then you can use pip to install package
And when you run code , you need to change to the pyth7

# 創建環境
Or you want to create new environment for other version

conda create --name [env_name] python=3.x
conda activate [env_name]
conda install ipykernel
python -m ipykernel install --user --name [kernel_name]
And you can get the new environment

## 禁止
不要在ipynb檔裡面用!pip install xxx
