Python program to print letter in an array backwards

Question

I have to print letters from an array backwards. I got all the letters to be backwards but I realized I used the sort method and I'm not allowed to use it. I can't figure out any other way. Any suggestions?

The output should be:

w

v

u

t

.
.
.

g

f

This is the code I have so far:

letter = ['f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w']
letter.sort(reverse=True)





for i in range(len(letter)):
print(letter[i])

@navodithshankar To keep names explicit, you should name your list `letters` and iterate `for letter in letters`. Often there is no need to use an index in Python. — Guimoute, Mar 09 '20 at 11:54

letter = ['f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w']
letter[::-1]

OR

reverseletter=letter[::-1]

letters = 'fghijklmnopqrstuvw'

for letter in reversed(letters):
    print(letter)

Strings work like lists. A string is a list of characters.
reversed() can be used to reverse the order of a list.
There is no need to use range()

you can use use the built-in function reversed :

print(*reversed(letter), sep='\n')

output:

w
v
u
t
s
r
q
p
o
n
m
l
k
j
i
h
g
f

*reversed(letter) will give as non-keyword arguments all the letters in reverse order for the print built-in function
the keyword argument sep='\n' will ensure that all the letters will be printed on a separate line

To reverse a list you can use.

Slicing [::-1]

for i in letters[::-1]:
    print(i)

You can use reversed.

for i in reversed(letter):
    print(i)

Note: reversed spits an iterator.

you can use revered() method to print it in reverse order such as below

letter = ['f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w']

for i in reversed(letter): 
    print(i)

You can directly use list indexing or slicing such as:

letter = ['f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w']

print(letter[::-1])
