Answer 1

The above-mentioned approaches are working but since a mixed list can also contain an integer value I added an extra checking.

def validate(num):
    try:
        return int(num)
    except (ValueError, TypeError):
        try:
            return float(num)
        except (ValueError, TypeError):
            return num


vals_ = ['cat' ,'s-3-f','7390.19','12']
new_list = [validate(v) for v in vals_]  

Output:

['cat', 's-3-f', 7390.1, 12]
