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

for sub in the_list:
    for key in sub:
        sub[key] = int(sub[key])

Gives it a casting as an int instead of as a string.

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")
