How do I make a string spell backwards?

Answer 1

it's very very simple!!

def spell(text):

#first store the text into a list
List=list(text)

#then reverse the list
reverse_list=List[::-1]

#now print the text elements vertically
for i in range(len(reverse_list)):
print(reverse_list[i])

text=input()
spell(text)

Answer 2

def spell(txt):
#obtain the size of txt
sizeTxt = len(txt)
#latest create a while with condition that sizeTxt != 0
while sizeTxt != 0:
#print text vertically
print(txt[sizeTxt-1])
#change the sizeTxt to avoid an infiniti loop
sizeTxt -= 1

txt = input()
spell(txt)

Answer 3

def spell(txt):
#your code goes here
if len(txt)==0:
return
else:
print(txt[len(txt)-1:len(txt)])
txt=txt[0:len(txt)-1]
spell(txt)

txt = input()
spell(txt)

Answer 4

I have the solution with recursive method:
def spell(text, size):
if size == (-1):
return ""
else:
return text[size] + "\n" + spell(text, size-1)

text = input()
size = len(text)-1

print(spell(text, size))
