Answer 1

这是一种pythonic方式。请注意，无论中间名有多少，它都会考虑所有名称。

name = input("Please enter a name: ")
names = name.split()
initials = [x[0] for x in names[:-1]]
print(*initials, names[-1])


"""
Broken down:
name.split() = ['Ted', 'David', 'Vivican', 'Mosby']   Note ive added an extra name for show
name.split()[:-1] = ['Ted', 'David', 'Vivican']
[x[0] for name in ['Ted', 'David', 'Vivican']] = ['T', 'D', 'V']
print(*initials) unpacks each value in the list to the function eg
print(*['T', 'D', 'V']) == print('T', 'D', 'V')
"""

Answer 2

使用split()分隔名称。然后打印每个名字的第一个字符，但是打印整个姓氏。

user = input('Please Enter your name \n')
names = user.split()

for i in range(0, len(names)):
    if i < len(names) - 1:
        # print first char only, no newline at the end
        print(names[i][0], end=" ") 
    else:
        # print entire last name
        print(names[i]) # print entire name

Answer 3

user = input('Please Enter your name \n')
length = len(user.split(" "))
value=0
print(length)
for a in user.split(" "):
   if(value==length-1):
      print(a)
   else:
      print(a[0],end=' ')
   value+=1
