是否有使用方法修改python变量的快捷方式? [英] Is there a good shortcut for modifying python variables using methods?

问题描述

i += 1代替i = i + 1.

string = string.replace(...)是否有类似的缩写?

Is there a similar shorthand for string = string.replace(...)?

推荐答案

否，因为没有内置语法.

No, because there is no built-in syntax for this.

对于字符串，您仍然可以使用+=:

For a string, you can still use +=:

>>> x = "hello"
>>> x += " world"
>>> x
'hello world'

因为+ =是为字符串定义的.只是没有可替换的赋值运算符.

Because += is defined for strings. There just isn't an assignment operator for replace.
