7-2 餐馆订位 :
编写一个程序, 询问用户有多少人用餐。 如果超过8人, 就打印一条消息, 指出没有空桌; 否则指出有空桌。
num = input('How many people are going to have dinner?\n') num = int(num) if num>8: print('Sorry, no table is available.') else: print('OK~')
7-3 10的整数倍 :
让用户输入一个数字, 并指出这个数字是否是10的整数倍。
num = input('input a number.\n') num = int(num) if num%10 == 0: print(str(num) + ' is an integer multiple of 10.') else: print(str(num) + ' is not an integer multiple of 10.')
7-7 无限循环 :
编写一个没完没了的循环, 并运行它(要结束该循环, 可按Ctrl +C, 也可关闭显示输出的窗口) 。
x = 0 while x<10: x = x-1
键盘打断指 ctrl+c
7-10 梦想的度假胜地 :
编写一个程序, 调查用户梦想的度假胜地。 使用类似于“If you could visit one place in the world, where would you go?”的提示, 并编写一个打印调查结果的代码块。
responses = {} flag = True while flag: name = input("\nWhat is your name? ") response = input("If you could visit one place in the world, where would you go?") responses[name] = response repeat = input("Would you like to let another person respond? (yes/ no) ") if repeat == 'no': flag = False # 调查结束, 显示结果 print("\n--- Poll Results ---") for name, response in responses.items(): print(name + " would love to visit " + response + " most.")
