Find the first maximum length even word from a string | Function to find maximum length even word.
To store length of current word ..
To store length of maximum length word ..
To store starting index of maximum length word ..
If current character is space then word has ended . Check if it is even length word or not . If yes then compare length with maximum length found so far ..
Set currlen to zero for next word ..
Update length of current word ..
Check length of last word ..
If no even length word is present then return - 1..
Driver code"
How can the above be solved in Python?

=====
Can you provide a code to find the first maximum length even word from a string and the other steps required?
