编写依次执行以下操作的程序: 要求用户输入他/她的生日。 要求用户输入他/她的姓氏。 按此顺序打印用户的姓氏和出生日期。
我正在上一门计算机科学课,这是入门级的问题集。我得到了正确的答案,但我不太明白为什么它要求“用户”输入两次姓名和生日。
我尝试编辑代码的前两行,即“原始打印”,我尝试在x和y =命令上方添加#descriptions,并且还编辑了几次打印您的姓名和生日的行。不太确定我缺少什么。
print raw_input('What is your birthday?')
print raw_input('What is your name?')
x = raw_input('What is your birthday?')
y = raw_input('What is your name?')
print "Your name and birthday are " + y + x
预期:
What is your birthday?1122
1122
What is your name?rudy
rudy
Your name and birthday are Rudy 1122
实际结果:
What is your birthday?1122
1122
What is your name?rudy
rudy
What is your birthday?1122
What is your name?rudy
Your name and birthday are rudy1122

获得两次提示的原因是,每次调用raw_input('x')
时,它将在控制台上提示用户。您有两个print
语句在脚本顶部执行此操作,然后在后面的两个调用中捕获了用户对变量的输入。
raw_input
会自动将括号中的短语打印给用户,因此您不需要先在脚本顶部打印它们,可以删除这些行,您应该会得到预期的结果。 / p>

您有两行可以打印
print raw_input('What is your birthday?') # this prints but you don't get the input from it
print raw_input('What is your name?') #this also prints
x = raw_input('What is your birthday?') #this and the following line are all you need
y = raw_input('What is your name?')
