除非已定义函数，否则无法调用该函数.将def createDirs():块移至文件顶部，位于导入的下方.

You can't call a function unless you've already defined it. Move the def createDirs(): block up to the top of your file, below the imports.

某些语言允许您在定义函数之前使用它们.例如，javascript将此称为吊装".但是Python并不是其中的一种语言.

Some languages allow you to use functions before defining them. For example, javascript calls this "hoisting". But Python is not one of those languages.

请注意，只要定义是在使用之前创建的，就可以在比创建函数的行高的行中引用该函数.例如，这是可以接受的:

Note that it's allowable to refer to a function in a line higher than the line that creates the function, as long as chronologically the definition occurs before the usage. For example this would be acceptable:

import os

def doStuff():
    if os.path.exists(r'C:\Genisis_AI'):
        print("Main File path exists! Continuing with startup")
    else:
        createDirs()

def createDirs():
    os.makedirs(r'C:\Genisis_AI\memories')

doStuff()

即使在第7行调用了createDirs()并且在第9行对其进行了定义，这也不是问题，因为def createDirs在doStuff()在第12行执行之前就执行了.

Even though createDirs() is called on line 7 and it's defined on line 9, this isn't a problem because def createDirs executes before doStuff() does on line 12.
