[FIXED] What is the difference between {} and [] in python?

Issue

What is the difference between columnNames = {} and columnNames = [] in python?

How can i iterate each one? using {% for value in columnNames %} OR for idx_o, val_o in enumerate(columnNames):

Solution

• columnNames = {} defines an empty dict
• columnNames = [] defines an empty list

These are fundamentally different types. A dict is an associative array, a list is a standard array with integral indices.

I recommend you consult your reference material to become more familiar with these two very important Python container types.
