Why dict.get(key) instead of dict[key]?

Question

Today, I came across the dict method get which, given a key in the dictionary, returns the associated value.

For what purpose is this funct

Answer 1

Based on usage should use this get method.

Example1

In [14]: user_dict = {'type': False}

In [15]: user_dict.get('type', '')

Out[15]: False

In [16]: user_dict.get('type') or ''

Out[16]: ''

Example2

In [17]: user_dict = {'type': "lead"}

In [18]: user_dict.get('type') or ''

Out[18]: 'lead'

In [19]: user_dict.get('type', '')

Out[19]: 'lead'
