Question

我知道这是错误的，因为'input（）'只能接受1个参数，但是我想在要求用户输入更多数字的同时在输入中包含这些变量：

Answer 1

您可以使用字符串格式和F字符串（仅适用于Python 3.6 +）

字符串格式：

n = 5
average = 0
for i in range(n):
    numbers = int(input('Please enter number {} of {} to average:'.format(i+1, n)))
    average = average+numbers/n

F字符串（适用于Python 3.6 +）：

n = 5
average = 0
for i in range(n):
    numbers = int(input(f'Please enter number {i+1} of {n} to average:'))
    average = average+numbers/n

Answer 2

您可以在将变量转换为字符串[str（x）]后尝试连接它们

n = 5
average = 0
for i in range(n):
    numbers = eval(input('Please enter number '+str(i+1)+' of '+str(n)+' to average:'))
    average = average+numbers/n

这是一种幼稚的方法，但是效果很好。

如何在输入函数中引用变量？
