[英]I have two version of python installed on my computer but one is not responding
[英]I think my computer has built in python 2 and I installed python 3
我的計算機上運行的是Windows 8,我想我同時下載了python 2和3,或者我認為我的計算機已內置python 2,並且下載了python3。現在當我在IDLE中運行代碼時,代碼可以正常工作,但是當我保存了程序,然后雙擊保存文件,該文件將運行,但無法像以前在IDLE中一樣工作。
有人可以解釋我當前可能遇到的問題嗎?
我只希望我的程序在IDLE和雙擊保存的文件中都能完美運行。
我嘗試了Anand S. Kumar的建議,但不確定我知道我在做什么。
所以這是我在CMD管理員中輸入的內容,但輸出仍然與上面的第一張圖片相同。
所以這是代碼

如果您不明白,請不要介意評論。 順便說一句,這是我的第一語言。
與.py
文件關聯的默認程序很可能是Python 2.x的可執行文件。 雙擊python文件時,這可能是它無法正常運行的原因。
因為雙擊文件(或在命令提示符下運行文件而不提供可執行文件)時,Windows會選擇與.py
文件關聯的默認程序,並使用該可執行文件運行文件。
就您而言,即使您安裝了Python 3,它仍可能指向Python 2。
在python 安裝文檔中 ,要更改Python文件的默認可執行文件,請使用-
您還可以使用pythonw.exe使所有.py腳本執行,例如通過常規功能進行設置(可能需要管理權限):
啟動命令提示符。
將正確的文件組與.py腳本相關聯:
assoc .py=Python.File
將所有Python文件重定向到新的可執行文件:
ftype Python.File=C:\\Path\\to\\python3.exe "%1" %*
使用上面的命令將.py
文件重定向到Python 3。
您可以嘗試將關聯更改為:
python.file="C:\Windows\py.exe" "%L" %*
或將“ C:\\ Windows ”部分設置為Python3.exe所在的位置。
Python安裝程序(至少適用於Python3)似乎指定文件名應使用寬字符格式; 因此, %L修飾符。
順便說一句。 您也可以在cmd-shell中使用ftype (而不是在Explorer中戳戳)。 未經測試,請當心:
ftype python.file=="C:\Windows\py.exe" "%L" %*
我從未嘗試過通過雙擊保存文件來運行Python程序,但是我可以為您指明如何在命令行或Python Shell中運行程序的方向。
首先,Windows不附帶Python 2或3。您可以通過簡單地轉到Python文件的安裝位置來檢查所使用的版本。 默認情況下,它們將位於C驅動器中。 設置好環境路徑后,您還可以通過Python shell檢查所使用的Python版本。
在這里 ,您可以找到設置環境以從命令行運行Python的步驟。 這也將幫助您建立環境。 本質上,您正在做的就是告訴Windows在命令行中鍵入“ python”時在哪里可以找到Python庫。 設置好環境后,您可以在命令行或Python Shell中運行文件。 查看Escualo的答案,了解如何執行此操作。
