Question

Write a Python program that asks the user to enter full name in the following format:
LastName, FirstName MiddleName
(for Example: "Hun, Attila The”).
The input will have a single space after the comma and only a single space between the first name and the middle name. Use string methods and operators in Python to convert this to a new string having the form:
FirstName MiddleInitial Period LastName (for example: "Attila T. Hun") and output it.
Be sure to test it with more than one input and not just "Hun, Attila The".
Sample Output 1:
Enter name in [LastName, FirstName MiddleName] format >Newton, Sir Isaac
The new name is : Sir I. Newton
Sample Output 2:
Enter name in [LastName, FirstName MiddleName] format >Hun, Attila The
The new name is : Attila T. Hun

没看懂。。。

你用什么版本的python呢？

Answer 2

字符串处理。。。追问

能具体点么

追答

lName = raw_input('Please enter your last name:')
fName = raw_input('Please enter your first name:')
mName = raw_input('Please enter your middle name:')
allName = "%s, %s %s"%(lName, fName, mName);
print allName
allName2 = fName + " " + mName[0:1] + ". " + lName#transform
print allName2

追问

#Enter name in [LastName, FirstName MiddleName] format >Newton, Sir Isaac
#The new name is : Sir I. Newton

output是这样。。。

追答

上面的代码不就是Sampl1， Sample2所要求的吗。

自己加个提示信息就可以了---

lName = raw_input('Please enter your last name:')
fName = raw_input('Please enter your first name:')
mName = raw_input('Please enter your middle name:')
allName = "%s, %s %s"%(lName, fName, mName);
print "#Enter name in [LastName, FirstName MiddleName] format >" + allName
allName2 = fName + " " + mName[0:1] + ". " + lName#transform
print "#The new name is :" + allName2

追问

题目是要求 Lastname, middle name和first name 一起输入，然后直接出结果。。

追答

哦 没细看。

print('Please enter your last name')
allName = ""
while(True):
    allName = raw_input()
    pattern = re.compile(r'[A-Z][a-z]*, [A-Z][a-z]* [A-Z][a-z]*')
    if pattern.match(allName):
        break
    else:
        print('format error, Please enter your name like "Hun, Attila The"')
[lName, fName, mName] = re.split(r"[, ]+", allName)
print allName
allName2 = fName + " " + mName[0:1] + ". " + lName#transform
print "#The new name is :" + allName2

Answer 3

full_name = raw_input('input full name:')
last, first, middle = full_name.split()
print '%s %s. %s' % (first, middle[0], last[:-1])
