could someone please help me convert this for loop into a while loop these are practice questions but i am so lost in how to do this. there are two for loops that needs to be converted and one while loop that needs to be converted to for loop which is number 3
1) for elt in string_list:
if elt.is_upp():
lower_list.append(elt.lower())
2) ret_list = []
for i in range (2, end, 4):
ret_list.append(i)
if '*' in in_list[i]:
ret_list[-1] = ret_list[-1]**2
3) j=0
