我该如何处理此回溯名称错误？ 这是我的第一个剧本

Question

The error is as follows

Traceback (most recent call last):

   sformat = parentFormat('start')

I'm guessing you're using Python 2.7 or lower.

parent = input(where + " Folder name (ex. Mol1-A) : ")

On this line, if the user types mol8 , the interpreter will look for the variable mol8 and try to assign it to parent . But this won't work because the variable mol8 doesn't exist. If you want parent to contain the string value "mol8" , use raw_input .

parent = raw_input(where + " Folder name (ex. Mol1-A) : ")

Alternatively, upgrade to Python 3, where raw_input has been renamed to input .
