ValueError: Not Enough Values to Unpack

Why This Happens

This is the inverse of 'too many values.' When you write a, b, c = iterable and it only has 2 elements, Python cannot fill all variables.

The Problem

line = 'Alice,30'
name, age, email = line.split(',')

The Fix

parts = line.split(',')
name = parts[0]
age = parts[1] if len(parts) > 1 else None
email = parts[2] if len(parts) > 2 else None

Step-by-Step Fix

1. 1

   Check element count

   Verify length matches variables before unpacking.

2. 2

   Use indexing with defaults

   Access by index with length checks.

3. 3

   Pad the iterable

   Extend: parts += [None] * (3 - len(parts)).
