Question

I’ve got dictionary with objects values and string keys:

dict{
'key1': object_1
'key2': object_2
}

And I’d like to convert it into:

dict{
'key1': str(object_1)
'key2': str(object_2)
}

Where str(object_1) is a string representation of object_1. What is the simplest and the most pythonic way of performing this transformation?

Answer 1

dict((k, str(v)) for k, v in d.iteritems())

or in Python2.7+:

{k: str(v) for k, v in d.items()}

For more complicated dicts (with tuples of objects as values):

dict((k, tuple(str(x) for x in v)) for k, v in d.iteritems())

{k: tuple(str(x) for x in v) for k, v in d.items()}
