# While And Input# input()# input() 接收一个参数: 即要向用户显示的提示或说明message = input("告诉我你想跟我说的话, 我会重复你的话~\n")
print("你说: " + message)# 使用 int() 来获取数值输入age = input("你多大?\n")
print('那么. 你明年' + str(int(age) + 1) + '了')# 使用 while 循环current_number = 1while current_number <= 5:
print(current_number)
current_number += 1# 1 2 3 4 5# 使用标志来控制循环activity = Truenum = 1while activity:
