在循环中如何创建不同的变量名? [英] How do you create different variable names while in a loop?

问题描述

出于示例目的...

for x in range(0,9):
    string'x' = "Hello"

所以我最终得到了string1，string2，string3 ...都等于"Hello"

So I end up with string1, string2, string3... all equaling "Hello"

推荐答案

当然可以；它称为词典:

d={}
for x in range(1,10):
        d["string{0}".format(x)]="Hello"

In [7]: d["string5"]
Out[7]: 'Hello'

In [8]: d
Out[8]: 
{'string1': 'Hello',
 'string2': 'Hello',
 'string3': 'Hello',
 'string4': 'Hello',
 'string5': 'Hello',
 'string6': 'Hello',
 'string7': 'Hello',
 'string8': 'Hello',
 'string9': 'Hello'}

我说的有点难以理解，但实际上将一个值与另一个值相关联的最佳方法是字典.这就是它的设计目的！

I said this somewhat tongue in check, but really the best way to associate one value with another value is a dictionary. That is what it was designed for!
