Xmas tree generator
Level: Intermediate (score: 3)
In this Bite you complete generate_xmas_tree that takes a rows arg (= height of the tree). For each row you print row_number*2-1 stars and center them, so for default height=10 the tree would look like this:
*
***
*****
*******
*********
***********
*************
***************

No printing to the console this time, you return this output from the function (use newlines / \n between the lines). Good luck and keep calm and code in Python!
