Question

编写一个程序，提示用户输入名字和姓氏。然后程序将打印姓氏和名字。如果用户仅输入一个名称，则给出错误消息。请帮助我的if语句。非常感谢

name = str(input("Your first and last names? "))
gap = name.find(" ")
name_length = len(name)
first = name[0:gap]
last = name[gap + 1 : name_length]
if name_length is 2:
    print("Name: ", last.upper(), ", ", first.capitalize(), sep = "")

else:
    print("ERROR: only one name found")

这些就是我除了：

安格斯猪油草

您的名字和姓氏？姓名：SNODGRASS，安格斯

安格斯

您的名字和姓氏？错误：只找到一个名字

Answer 1

尝试一下：

name = input("Your first and last name: ").split(" ")
if len(name) == 2:
    print("Name: ", name[0].upper(), ", ", name[1].capitalize(), sep = "")
else:
    print("ERROR: unknown number of names found!")

输出：

 ==== RESTART: C:/Users/...
Your first and last name: anGUS snodgrass
Name: anGUS, snodgrass
>>> 
==== RESTART: C:/Users/...
Your first and last name: anGUS
ERROR: unknown number of names found!
>>>

Answer 2

尝试此简单方法：

print("Enter your First and Last Name")
name = raw_input()
first,last = name.split()
print("Your FirstName:")
print(last.upper())
print("Your LasttName:")
print(first.lower())

Answer 3

x=input("Your first and last names : ").split()
if(len(x)<=1):
    print("name does not contain lastname or whole name is not mentioned ")
else:
    print(x[1]+" "+x[0])
