希望结束一段时间:循环与中断

Question

nc = dict(zip(nation,cap)) 
print("Countries and Capitals :{}".format(nc))

k = 0
while k != 5:
k = input("input : ")
if k == 1:
break
if k != 1:
key = k
print("The capital of {} is {} ".format(key,nc[key]))

#这只会在我键入1时出错。我希望它在按下1时停止程序。我该怎么办？

Answer 1

input("input ")返回一个字符串。

你可以做：

nc = dict(zip(nation,cap)) 
print("Countries and Capitals :{}".format(nc))

k = 0
while k != 5:
k = int(input("input : "))
if k == 1:
break
if k != 1:
key = k
print("The capital of {} is {} ".format(key,nc[key]))

Answer 2

input()返回字符串
因此，您需要使用int()函数将k作为整数输入。

k = int(input("input..."))
