Two small ways to convert a Python list to a dictionary

1. Now there are two lists , list1 = [' Key1 ', ' key2 ', ' Key3 '] and list2 = [' 1 ', ' 2 ', ' 3 '], convert them into such dictionaries : {' 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, the nested list into a dictionary , there are two ways,

>>>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, key on the left, value on right

...

>>> new_dict

{' Key3 ': ' Value3 ', ' key2 ': ' value2 ', ' key1 ': ' value1 '}
