Numeric elements of a mixed list
 

Right now I have a mixed list of different types of elements:

mixed_list = [1, 0.5, 0, 3, 'a', 'z']



print max(mixed_list)  # shows z, but would like it to be 3

How can I find the maximum numeric element of the list?

The easiest way is to extablish a temporary list of numeric values ...

mixed_list = [1, 0.5, 0, 3, 'a', 'z']



print max(mixed_list)  # shows z, but would like it to be 3

 

number_list = []

for x in mixed_list:

    if type(x) in (int, float):

        number_list.append(x)

 

print number_list

print max(number_list)  # 3

You can shorten this with a list comprehension ...

mixed_list = [1, 0.5, 0, 3, 'a', 'z']

 

print max([x for x in mixed_list if type(x) in (int, float)])  # 3
