max/min function on list with strings and integers

Question

I've got a list with strings and integers and want to find the minimum value of the integers, without list-slicing. Is there a work-around?

arr = [5,3,6,"-",3,"-",4,"-"]    
for i in range(len(set(arr))):
        cut = min(arr)

Many Thanks!

Answer 1

You could filter the non numeric using a generator expression:

arr = [5,3,6,"-",3,"-",4,"-"]
result = min(e for e in arr if isinstance(e, int))
print(result)

Output
