SyntaxError: EOL While Scanning String Literal

Why This Happens

Python expects strings to be closed on the same line. If the closing quote is missing, Python reaches end of line while still inside the string.

The Problem

message = 'Hello, World
print(message)

The Fix

message = 'Hello, World'
print(message)

# Multi-line:
message = '''Hello,
World'''

Step-by-Step Fix

1. 1

   Find the unclosed string

   Look for a string missing its closing quote.

2. 2

   Match quote types

   Opening and closing quotes must match.

3. 3

   Use triple quotes

   Use triple quotes for multi-line strings.
