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.

In Python, we can use float() to convert String to float. and we can use int() to convert String to an integer.
We can convert a string to float in Python using the float() function. This is a built-in function used to convert an object to a floating point number. Internally, the float() function calls specified object __float__() function.
To convert a string to integer in Python, use the int() function. This function takes two parameters: the initial string and the optional base to represent the data. Use the syntax print(int("STR")) to return the str as an int , or integer.
To convert dictionary values to list sorted by key we can use dict. items() and sorted(iterable) method. Dict. items() method always returns an object or items that display a list of dictionaries in the form of key/value pairs.
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")
