Manipulate Dictionary in python

Question

I have dict like this:

d = {'A1': 200,
 'A2': 150,
 'A3': 100}

I want to multiply each element by 2 but the newvalue can't be more than 300. for above example my output will be..

d_final = {'A1': 300,
 'A2': 300,
 'A3': 200}

Can this be done using lambda or map??

Answer 1

You can simply do a dict comprehension.

d_final = {k: min(2*v, 300) for k,v in d.items()}
