Replacing in a list Help!

[joshuawilson11]

Hi so in my list i have multiple characters - '32' which i need to replace with a space, would anybody be able to give an example of how to
do this? Thanks

Try

L[:] = [(' ' if x == '32' else x) for x in L]

It still hasn't worked, here's the output

[83, 111, 109, 101, 119, 104, 101, 114, 101, 32, 105, 110, 32, 108, 97, 32, 77, 97, 110, 99, 104, 97, 44, 32, 105, 110, 32, 97, 32, 112, 108, 97, 99, 101, 32, 119, 104, 111, 115, 101, 32, 110, 97, 109, 101, 32, 73, 32, 100, 111, 32, 110, 111, 116, 32, 99, 97, 114, 101, 32, 116, 111, 32, 114, 101, 109, 101, 109, 98, 101, 114, 44, 32, 97, 32, 103, 101, 110, 116, 108, 101, 109, 97, 110, 32, 108, 105, 118, 101, 100, 32, 110, 111, 116, 32, 108, 111, 110, 103, 32, 97, 103, 111, 44, 32, 111, 110, 101, 32, 111, 102, 32, 116, 104, 111, 115, 101, 32, 119, 104, 111, 32, 104, 97, 115, 32, 97, 32, 108, 97, 110, 99, 101, 32, 97, 110, 100, 32, 97, 110, 99, 105, 101, 110, 116, 32, 115, 104, 105, 101, 108, 100, 32, 111, 110, 32, 97, 32, 115, 104, 101, 108, 102, 32, 97, 110, 100, 32, 107, 101, 101, 112, 115, 32, 97, 32, 115, 107, 105, 110, 110, 121, 32, 110, 97, 103, 32, 97, 110, 100, 32, 97, 32, 103, 114, 101, 121, 104, 111, 117, 110, 100, 32, 102, 111, 114, 32, 114, 97, 99, 105, 110, 103, 46]
Here's the code for reference,

L[:] = [(' ' if x == 32 else x) for x in L]

although I would just remove the element instead of replacing it

Hmm ...

Not sure what you want to replace with what.
