2.12LAB: Name format

Many documents use a specific format for a person's name. code program whose input is:

firstName middleName lastName

and whose output is:

lastName, firstInitial.middleInitial.

Ex: If the input is:

Pat Silly Doe 

the output is:

Doe, P.S. 

If the input has the form:

firstName lastName

the output is:

lastName, firstInitial.

Ex: If the input is:

Julia Clark 

the output is:

Clark, J. 

What I was given by one of the tutors here:

Name = input() #split the name into list and store them into list variable #list[0] --first name #list[1] --middle name #list[2] --last name list = Name.split(' ') #check if length is 2 if len(list)==2: print(list[1]+",",list[0][0]+".") else: print(list[2]+",",list[0][0]+"."+list[1][0]+".") 

I'm getting a:

Traceback (most recent call last):

File "main.py", line 20, in

print(list[2]+",",list[0][0]+"."+list[1][0]+".")

IndexError: list index out of range

please help!
