switching keys and values in a dictionary in python [duplicate]

Answer 1

You can do it like this:

Function:

def inverse_dict(my_dict):
    updated_dict = {}

for i in my_dict:
    updated_dict[my_dict[i]] = [i]

return updated_dict

Main():

def main():
    year = {'day': 15, 'month': 3, 'year': 2019}
    print(inverse_dict(year))

if __name__ == "__main__":
    main()

Ouput:

{15: ['day'], 3: ['month'], 2019: ['year']}
