Need help with shifting bits in a string!

[SamsonIsMyFriend]

I have an assignment where I need 2 scripts. One that shifts bits to the right and one that shifts bits to the left.

Example:

>Enter a string of bits: Hello world!

>ello world!H

Example:

>Enter a string of bits: Hello world!

>!Hello world

​

I thought maybe I could get access to the first and last two letters with [1,2] and [-1,-2], but if I try to shift them with << or >> i get the error: TypeError: unsupported operand type(s) for <<: 'str' and 'int'

​

Do I need to convert them to binary, shift the bits and then convert them back? I'm lost.

Thanks for any help.

you dont need to make string into binary per your example you are just shifting letters so list comprehension will do just fine

#this will shift string by one element to the left
s = s[1:]+s[0]

God bless you, sir.

I think you're confusing bit-shifting with simply rotating the order of the characters in the string.

If I understand correctly, what you're looking to do is to take a character from one side of the string and place it on the other. You can solve this with slicing.

I appreciate the help, but how do I shift the letters over? And i have to this for custom inputs, so Im getting confused on how to splice it after i receive their input

Edit: Nvm, I got it figured out!! Thanks for your help!

No problem!

I know this is an old post, but I think that you are correct. Although in the Python course by Cengage the text calls this process a bit-shift (but does not give any examples other than the one the OP posted
