Write a function sum_name_length that consumes no parameters and produces no value.The function will repeatedly ask the user to enter names until the empty string is entered.The function then displays the sum of the lengths of all names entered. This is illustrated inthe example below (where the user’s input is indicated in bold):Enter a name: ChesterEnter a name: PixelEnter a name: LaptopEnter a name: WhiskersEnter a name:The sum of all name lengths is 26You may assume that a name does not contain any space characters.謝謝了~

如果只需要非空格名字的話就這樣：
#-*- coding: utf-8 -*-
import re
def sum_name_length():
sumLen=0
while True:
s=raw_input("Enter a name:")
if s=="":
break
elif re.search(r"\s",s):
print "Contains should not contains spaces!"
continue
else:
sumLen+=len(s)
print "The sum of all name lengths is %d"%sumLen
if __name__=="__main__":
sum_name_length()
改良版（名字只能是字母):
#-*- coding: utf-8 -*-
import re
def sum_name_length():
sumLen=0
while True:
s=raw_input("Enter a name:")
if s=="":
break
elif re.search(r"\s",s):
print "Contains should not contains spaces!"
continue
elif re.search(r"[^a-zA-Z]",s):
print "Name should only contains alphabet!"
continue
else:
sumLen+=len(s)
print "The sum of all name lengths is %d"%sumLen
if __name__=="__main__":
sum_name_length()

def sum_name_length():
print 'Enter your names, I will displays the sum of the lengths of all names entered'
length = 0
while True:
s = raw_input('Enter a name: ')
if s == '': break
length += len(s)
print 'The sum of all name lengths is', length
if __name__ == '__main__':
sum_name_length()
