Give me a code to decrypt a string according to given rules and the other steps required given the following:
Decrypt a string according to given rules | Function to return the original string after decryption.
Stores the decrypted string.
If length is odd.
Step counter.
Starting and ending index.
Iterate till all characters are decrypted.
Even step.
Odd step.
If length is even.
Step counter.
Starting and ending index.
Even step.
Odd step.
Reverse the decrypted string.
Driver Code"
How can the above be solved in Python?
