Python 100天-從新手到大師學習筆記Day01:初識Python

開啟CMD終端機

python --version
print('hello, world!')#可使用程式碼編輯工具如Sublime、Atom、、VSCode另存成hello.py
#cd到hello.py的目錄
#執行程式
python hello.py

註解

# print('hello world')
"""
多行註解使用三個引號開頭,三個引號結尾
print('My First Python Program - hello, world!')
Version: 9.9.9

IDE開發工具

IDLE(Python安裝時內建)IPython(使用Tab可自動補齊程式)Jupyter Notebook(多用於數據分析、機器及深度學習)Anaconda(數據科學神器,一次搞定所有安裝問題)Miniconda(檔案比Anaconda小,只包含Conda和Python)------------------------------------------------------------
Sublime Text(啟動很迅速的程式碼編輯器),推薦安裝以下Package
安裝Package Control - Ctrl+Shift+P1.Emmet2.ConvertToUTF83.Sidebar Enhancements4.SublimeCodeIntel(自動補全)5.Python PEP8 Autoformat(自動化格式)
------------------------------------------------------------
PyCharm(眾多人推薦的Python開發IDE)
Gitpod(一鍵編輯Github上的程式,線上版IDE)
