Syntax Error

What This Error Means

In Python, the syntax for a dictionary (or a mapping in general) requires a colon (:) after the key. Without it, Python will throw a Syntax Error.

Why It Happens

This error occurs when a developer forgets to add a colon after the key in a dictionary or a mapping in Python, which leads to a syntax mismatch.

How to Fix It

1. 1To fix this error, simply add a colon after the key in the dictionary or mapping. For example, change 'if key' to 'if key:'.

Example Code Solution

my_dict = {'key': value} if True else {}

my_dict = {'key': value} if True else {'key': value}
