A another approach that I have tried using args:

def myfunc(*args):
mystr = str(args)
new_list = list(mystr)
length = len(new_list)
order_list = []
final = ''
even = (mystr[0:length:2].lower())
l_even = len(even) - 1
odd = (mystr[1:length:2].upper())
l_odd = len(odd) - 1

while length !=0:
    if length%2 != 0:
        order_list.append(even[l_even])
        l_even = l_even - 1
    else:
        order_list.append(odd[l_odd])
        l_odd = l_odd - 1
    length = length -1
order_list.reverse()
for i in order_list:
    final = final + i
return final

this is good to add any number of arguments that can be fit for this usecase
