strings in Python are immutable - in other words, they cannot be updated in place as you're doing above. However, that doesn't mean you can't achieve what you're after. In Python, the way to approach this problem since you cannot modify the string in place, is to create a new string object with the desired content:
Also note, that you are just extracting one char from the string
into another variable (which you then change) and you are *not*
getting any "reference" to the char in the string.
As has been alreagy told, use the str.replace() function
.
