Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
Thanks!
Thank you! I was really beating my head against the wall on this one. Before changing these test statements, the program kept printing a value of "None". When I changed it to what you suggested though it worked.
There are mistakes in the CALCULATE VOLUME OF A SPHERE integration test drivers.
x_print(output_volume(15.3, calculate_volume(15.3)))
x_print(output_volume("10.0", calculate_volume("10.0")))
x_print(output_volume(15, calculate_volume(15)))
should be
output_volume(15.3, calculate_volume(15.3))
output_volume("30.0", calculate_volume("30.0"))
output_volume(15, calculate_volume(15))
