python Two small ways to turn a list into a dictionary Summary of of

1. Now there are two lists, list1 = ['key1', 'key2', 'key3'] and list2 = ['1', '2', '3']. Turn them into dictionaries like this: {'key1': '1', 'key2': '2', 'key3': '3'}

>>>list1 = ['key1','key2','key3']

>>>list2 = ['1','2','3']

>>>dict(zip(list1,list2))

{'key1':'1','key2':'2','key3':'3'}

2. There are two ways to turn nested lists into dictionaries.

>>>new_list= [['key1','value1'],['key2','value2'],['key3','value3']]

>>>dict(list)

{'key3': 'value3', 'key2': 'value2', 'key1': 'value1'}

Or this:

>>>new_list= [['key1','value1'],['key2','value2'],['key3','value3']]

>>>new_dict = {}

>>> for i in new_list:

...  new_dict[i[0]] = i[1]        # Dictionary assignment, left side is key On the right value

...

>>> new_dict

{'key3': 'value3', 'key2': 'value2', 'key1': 'value1'}
