List comprehension replacing items that are not float or int

Question

I have a 2 item list.

Sample inputs:

[\'19(1,B7)\', \'20(1,B8)\']
[\'16 Hyp\', \'16 Hyp\']
[\'< 3.2\', \'38.3302615548213\']
[\'18.6086945477694\         


        

Answer 1

This looks more like a true list comprehension way to do what you want...

def isfloat(string):
    try:
        float(string)
        return True
    except:
        return False

[float(item) for s in mylist for item in s.split() if isfloat(item)]
#[10000.0, 5398.38770002321]

Or remove the float() to get the items as strings. You can use this list comprehension only if '>' or '<' are found in the string.
