“元组"对象不可调用 - Python [英] 'Tuple' object is not callable - Python

问题描述

我正在使用 pygame 并且我正在使用一个函数来设置文本的选定位置在 PyGame 中:

I'm using pygame and I'm using a function that set the selected position of a text in PyGame :

def textPos(YPos , TextSize):
    TextPosition.center(60,YPos)
    print("Size : " + TextSize)

但是当我运行程序时，出现错误:

but when I run the program, I get an error:

TextPosition.center(60,YPos) : TypeError : 'Tuple' object is not callable 

有办法解决这个问题吗?

There's a way to solve this problem?

推荐答案

'Tuple' object is not callable 错误意味着您将数据结构视为函数并尝试在其上运行方法.TextPosition.center 是元组数据结构而不是函数，您将其作为方法调用.如果您尝试访问 TextPosition.Center 中的元素，请使用方括号 []

'Tuple' object is not callable error means you are treating a data structure as a function and trying to run a method on it. TextPosition.center is a tuple data structure not a function and you are calling it as a method. If you are trying to access an element in TextPosition.Center, use square brackets []

例如:

foo = [1, 2, 3]
bar = (4, 5, 6)

# trying to access the third element with the wrong syntax
foo(2) --> 'List' object is not callable
bar(2) --> 'Tuple' object is not callable

# what I really needed was
foo[2]
bar[2]
