Hello @sivaramkrishnanethet, there is no output because your function is returning None. If you want your function to print the output do not assign it to a variable when calling it.
instead of above, just call the function without assigning it to a variable:
The assignment here is of course unnecessary. But this does not affect the print statements that we are doing in the function. It must be printed if we have print statement in the function regardless of whatever return type of the function.
