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])
letters = 'fghijklmnopqrstuvw'
for letter in reversed(letters):
print(letter)
reversed() can be used to reverse the order of a list.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 functionsep='\n' will ensure that all the letters will be printed on a separate line
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]
To reverse a list you can use.
[::-1]for i in letters[::-1]:
print(i)
reversed.for i in reversed(letter):
print(i)
Note:
reversedspits 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])
for i in letter[::-1]: print(i)lettersand iteratefor letter in letters. Often there is no need to use an index in Python.
