Generate n | This function generates all n bit Gray codes and prints the generated codes.
Base case.
Recursive case.
Append 0 to the first half.
Append 1 to the second half.
Function to generate the Gray code of N bits.
Print contents of arr.

How can the above be solved in Python?
 ... Give me a code to generate n and the other steps required?
