Answer 1

code = input()[::-1]

lst=["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z"," "]

for i in range(len(code)):
if code[i] == lst: #comparing with total list instead of single character. instead use code[I] in lst:
sentence == "" #no effect sentence , are you trying to assigne? then use = operator, == is a comparision operator, but declare this sentence outside and before loop, otherwise each time it overrites value
sentence =+ code[i] #use += , not =+

print(sentence)

# instead of list , you can use isalpha() function

edit:

your missing space count..
Space must be in output as it is as in input reversed way.. isspace() helps to check.

Answer 2

aazizul zainal ,

instead of using the alphabet as a reference for checking each character, we could also use the string methods:

.isalpha()
.isspace()

to get the task done:

...
for char in ...:
if char.isalpha() or ...:
...

Answer 3

code = input()[::-1]

lst=["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z"," "]
sentence = ""
for i in range(len(code)) :
if code[i] in lst:

sentence += code[i]

print(sentence)

Answer 4

If anyone got any idea how can i approach this problemm,feel free too critics or give me any suggestion for my next python project, i really stuck on this one :/

Answer 5

aazizul zainal

just remove all the number and special characters(except spces) from the sample input

after that you will have a string of only letters

reverse that strings

you will get your output

Note carefully there is a space between W and *

in your current code you are not checking for the presence of code[i] in lst[i]

line 7 needs = operator not ==
line 8 should be += not =+
