在每个列表元素上调用 int() 函数? [英] Call int() function on every list element?

问题描述

我有一个包含数字字符串的列表，如下所示:

I have a list with numeric strings, like so:

numbers = ['1', '5', '10', '8'];

我想将每个列表元素转换为整数，所以它看起来像这样:

I would like to convert every list element to integer, so it would look like this:

numbers = [1, 5, 10, 8];

我可以使用循环来完成，就像这样:

I could do it using a loop, like so:

new_numbers = [];
for n in numbers:
    new_numbers.append(int(n));
numbers = new_numbers;

有必要这么丑吗?我确信在一行代码中有一种更 Pythonic 的方式来做到这一点.请帮帮我.

Does it have to be so ugly? I'm sure there is a more pythonic way to do this in a one line of code. Please help me out.

推荐答案

这就是 列表推导式 用于:

numbers = [ int(x) for x in numbers ]
