So i have this dict:
role_positions = {role1: 1, role2: 2, role3: 3}
How do i reverse the values of it? like this:
role_positions = {role1: 3, role2: 2, role3: 1}
>Solution :
You can get values as a list then reversed them and zip with keys and return dict like below:
# python_version > 3.8
>>> dict(zip(role_positions, reversed(role_positions.values())))
{'role1': 3, 'role2': 2, 'role3': 1}
# python_version < 3.8
>>> dict(zip(role_positions, reversed(list(role_positions.values()))))
For older versions of python, for sure about the order of different run-time we need to get the inputted dict as OrderedDict: (here we can read a good explanation)
We suppose we get OrderDict as input, below code is only used for creating OrderDict. if we use the below code in the older version maybe we get a different OrderedDict (because role_positions maybe get a different order) but we suppose the user input OrderDict
from collections import OrderedDict
# we supoose we input below dict
o_dct = OrderedDict((k, v) for k,v in role_positions.items())
dict(zip(o_dct, reversed(list(o_dct.values()))))
