How to Replace a single, unknown, index in a 2d list in python

How would I be able to replace a single index in a 2d list if we don't know what value is currently in that location?

Initially, i thought 

twoDList[0][0].replace('A')

would work; however, it does not. So what is the proper way to replace an index in a 2d list in python?

.replace does not do in place replacements since strings are immutable, rather it returns a copy of the string. make sure to set the new value to the item:

tw0dList[0][0] = 'A'
