def myfunc(x):
    out = []
    for i in range(len(x)):
        if i%2==0:
            out.append(x[i].lower())
        else:
            out.append(x[i].upper())
    return ''.join(out)

my solution:
def myfunc(x):
x=list(x)
for i, letra in enumerate(x):
if i%2 ==0:
x[i]=letra.upper()
else:
x[i]=letra.lower()
return ''.join(x)

My solution:

My humble solution:

def myfunc(*args):
    
    final_sentence = ''
    
    for index, char in enumerate(*args):
        if index % 2 == 0:
            final_sentence += char.upper()
        else:
            final_sentence += char.lower()
            
    return final_sentence

reutn ' '.join(out)

I think this approach is much better than using the len property inside the range
