Hi all.

I've made a small function which, given a tuple, compares if all elements in this tuple is of the same sign.

E.g., tuple = [-1, -4, -6, -8] is good, while [-1, -4, 12, -8] is bad. I am not sure I've made the smartest implementation, so I know this is the place to ask.

def check_consistent_categories(queryset):
try:
    first_item = queryset[0].amount

    if first_item < 0:
        for item in queryset:
            if item > 0:
                return False
        return True
    else:
        for item in queryset:
            if item < 0:
                return False
        return True
except:
    return False
