We have seen that lists are mutable (they can be changed), and tuples are immutable (they cannot be changed).
Let's try to understand this with an example.
You are given an immutable string, and you want to make changes to it.
You can access an index by:
What if you would like to assign a value?
How would you approach this?
One solution is to convert the string to a list and then change the value.
Another approach is to slice the string and join it back.
Read a given string, change the character at a given index and then print the modified string.
Complete the mutate_string function in the editor below.
mutate_string has the following parameters:
- string string: the string to change
- int position: the index to insert the character at
- string character: the character to insert
string: the altered string
The first line contains a string, .
The next line contains an integer , the index location and a string , separated by a space.
