Write me a code to minimum cost to convert str1 to str2 with the given operations and the other steps required given the following:
Minimum cost to convert str1 to str2 with the given operations | Function to return the minimum cost to convert str1 to sr2.
For every character of str1.
If current character is not equal in both the strings.
If the next character is also different in both the strings then these characters can be swapped.
Change the current character.
Driver code"
How can the above be solved in Python?

#Here is code to minimum cost to convert str1 to str2 with the given operations and the other steps required.
