input向用户显示提示，接受用户输入，像是把C中的printf和scanf结合了起来，不用像C那样提示还得单独写一行
1 age = input("how old are you?")
将用户输入转换为数值
1 age = input("how old are you?") 2 age = int(age)#将数字的字符型转变为数值 3 if age > 18: 4 print("adult") 5 输入 19 6 输出为：adult
while循环不断运行，直到不满足指定条件，而for循环是让每个元素执行一次代码块
while可以根据用户的输入来确定何时退出循环，和c一样有使用break和continue来退出
1 prompt = "\nplease enter the name of a city you have visited:" 2 prompt += "\n(enter ‘quit‘ when you are finished.)" 3 while 1: 4 city = input(prompt) 5 if city == ‘quit‘: 6 break#退出循环 7 else: 8 print("i‘d love to go to "+city)
