Question

我正在创建一个看起来像这样的循环

players = int(input('How many players? '))
for i in range (0,players):
   name = input('What is your name? ')

然后我希望下一个变量为'value_of_'，然后是他们输入的内容，因为他们的名字将在变量的名称中。

Answer 1

例如，您需要将输入值存储在某个列表中。实现您想要的简洁方法是：

playernames = [input('What is your name? ') for _ in range(players)]

您还可以使用字典将字符串'player_nr_X'映射到这样的播放器名称：

playernames = {'player_nr_' + str(i + 1) : input('What is your name? ') for i in range(players)}

当然，您也可以在字典中使用整数键。

演示：

>>> players = 3
>>> {'player_nr_' + str(i + 1) : input('What is your name? ') for i in range(players)}
What is your name? 'bob'
What is your name? 'alice'
What is your name? 'jeff'
{'player_nr_1': 'bob', 'player_nr_2': 'alice', 'player_nr_3': 'jeff'}

Answer 2

计算变量名称是一个坏主意，它们使编写代码更加困难。你想要做的是使用字典，其中键是名称。

例如：

values = {}
players = int(input('How many players? '))
for i in range (0,players):
   name = input('What is your name? ')
   value[name] = i

或者，如果要将索引值用作键，将名称用作值：

value[i] = name

将变量调用为另一个变量的值
