Python _Anaconda軟體安裝及Jupyter Notebook操作筆記

距離上次安裝使用ANACONDA已經相隔7年了> ~ < |||

建置python的開發環境_開始_基本輸出_數學計算

安裝上一些步驟都有一些連結失效等問題

最近修學分班剛好又要接觸到此工具

Spyder就是Anaconda安裝完後附帶的IDE

Spyder我們點RUN綠色撥放就可執行程式

預設會把每次這個變數宣告相關暫存到所謂IPython環境裏頭(記憶體會keep住)

測試小範例

1 2 3 4 5 6 7 8 9 10 11 12 13

# -*- coding: utf-8 -*- """ Spyder Editor This is a temporary script file. """ import numpy as np a = np.array([1,2,3,4]) print(a) b = 1 c=3.14

Jupyter Notebook操作筆記

預設在C槽做程式應用開發建置

若想更換路徑可以

開啟cmd之後cd指定目錄在下jupyter notebook指令

要注意此terminal的process若中斷則notebook瀏覽器預設開啟的也會掛掉

notebook不僅可寫程式還能做筆記

你可新增一個程式檔案

你每執行一行按上面RUN即可

基本上由上至下scan只要在同一個文檔程式中定義

生命週期就同一個可識別的到之前前面宣告過的變數

相比Spyder美中不足之處就是沒有語法自動跳出來提示以及變數側欄可去檢視目前存於記憶體中宣告了多少捨麼型別的變數

要自己print出來查看

要注意的一點就是你每打一行都會寫入存至ipynb文檔中

以下是其存入的內容
