Dictionary elements to string

Question

I'm looking for an elegant way to encode values of dictionary objects to the string type. Like the following:

{"a":"b","c":1,"e":None,"g":True}

to

{"a":"b","c":"1","e":"None","g":"True"}

Thank you a lot!

Answer 1

simple with another dict comprehension:

a = {"a":"b","c":1,"e":None,"g":True}
a = {k:str(v) for k,v in a.items()}

or if you don't want to rebuild the dictionary, do it the old way:

for k in a.keys():
    a[k] = str(a[k])

(BTW no fear of overhead of converting already existing str to str: Should I avoid converting to a string if a value is already a string?)
