除非已经定义了函数,否则不能调用它.将 def createDirs():
块移动到文件顶部,在导入下方.
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.
有些语言允许您在定义函数之前使用它们.例如,javascript 将此称为提升".但 Python 不是这些语言之一.
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,在比创建函数的行高的行中引用函数是允许的,只要按时间顺序定义出现在使用之前.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_AImemories')
doStuff()
即使 createDirs()
在第 7 行调用并在第 9 行定义,这也不是问题,因为 def createDirs
在 doStuff()
在第 12 行.
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.
