How to check a string for emptyness or length zero

Question

I recently asked a question about converting list of values from txt file to dictionary list. You can see it from the link here: See my question here

P883, Michael Smith, 1991

L672, Jane Collins, 1992

(empty line here)

L322, Randy Green, 1992

H732, Justin Wood, 1995(/added)

^key    ^name        ^year of birth 

===============
this question has been answered and i used the following code (accepted answer) which works perfectly:

def load(filename):
         students = {}

   infile = open(filename)
   for line in infile:
       line = line.strip()
       parts = [p.strip() for p in line.split(",")]
       students[parts[0]] = (parts[1], parts[2])
   return students 

however when there is a line space in the values from the txt file.. (see added parts) it doesnt work anymore and gives an error saying that list index is out of range.

Answer 1

Check for empty lines inside your for-loop and skip them:

for line in infile:
    line = line.strip()
    if not line:
        continue
    parts = [p.strip() for p in line.split(",")]
    students[parts[0]] = (parts[1], parts[2])
