类型错误:“dict"对象不可调用 [英] TypeError: 'dict' object is not callable

问题描述

我正在尝试遍历输入字符串的元素，并从字典中获取它们.我做错了什么?

I'm trying to loop over elements of an input string, and get them from a dictionary. What am I doing wrong?

number_map = { 1: -3, 2: -2, 3: -1, 4: 1, 5: 2, 6: 3 }
input_str = raw_input("Enter something: ")
strikes = [number_map(int(x)) for x in input_str.split()]

<小时>

strikes  = [number_map(int(x)) for x in input_str.split()]
TypeError: 'dict' object is not callable

推荐答案

访问给定键的 dict 的语法是 number_map[int(x)].number_map(int(x)) 实际上是一个函数调用，但由于 number_map 不是可调用的，所以会引发异常.

The syntax for accessing a dict given a key is number_map[int(x)]. number_map(int(x)) would actually be a function call but since number_map is not a callable, an exception is raised.
