Please tell me why this code is not outputting the desired output?It always prints z.

Question

x=input()
y=["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"]
m=['Z', 'Y', 'X', 'W', 'V', 'U', 'T', 'S', 'R', 'Q', 'P', 'O', 'N', 'M', 'L', 'K', 'J', 'I', 'H', 'G', 'F', 'E', 'D', 'C', 'B', 'A']
if y[1].lower or y[1] in x:
print(m[1].lower())
elif y[0].lower or y[0] in x:
print(m[0].lower())

here is a try with some comments. it uses everything in lower case letter. the 2 alphabets do not need to be lists, can also be strings.
it uses a for loop, that iterates over the input string, check if character is in alphabet, get its index, and pick the character at then same index. then add it to the string.
there are various ways to do this task. most of them may be more elegant, much shorter or more efficient. don't care about at this time. it is important that you understand the steps. later on you can make more version. happy coding!

txt = input().lower()
alph_asc = "abcdefghijklmnopqrstuvwxyz " # alphabet ascending order
alph_rev = "zyxwvutsrqponmlkjihgfedcba " # alphabet reverse order

new_str = ""
for char in txt: # iterate through input
if char in alph_asc: # make sure that char exists
ind = alph_asc.index(char) # get index position of char
new_str += alph_rev[ind] # use char at the same index
print(new_str)

Vaibhav Tiwari ,

as you can see, people have started guessing due to lack of a description. please give a complete and clear description what your code should achieve. add also an input sample and the expected output.

thanks!

Answer 7

if the code is suppossed to print the word with corresponding values from the other list then it should run as shown below..................................

x=input()
y=[" ","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"]
m=[' ','Z', 'Y', 'X', 'W', 'V', 'U', 'T', 'S', 'R', 'Q', 'P', 'O', 'N', 'M', 'L', 'K', 'J', 'I', 'H', 'G', 'F', 'E', 'D', 'C', 'B', 'A']
x=x.upper()
lst=[]
for i in x:
if i in y:
z=y.index(i)
lst.append(m[z].lower())

print("".join(lst))
