python - How to convert string values from a dictionary, into int/float datatypes?

Question

I have a list of dictionaries as follows:

list = [ { 'a':'1' , 'b':'2' , 'c':'3' }, { 'd':'4' , 'e':'5' , 'f':'6' } ]

How do I convert the values of each dictionary inside the list to int/float?

So it becomes:

list = [ { 'a':1 , 'b':2 , 'c':3 }, { 'd':4 , 'e':5 , 'f':6 } ]

Thanks.

Answer 1

Gotta love list comprehensions.

[dict([a, int(x)] for a, x in b.items()) for b in list]

(remark: for Python 2 only code you may use "iteritems" instead of "items")
