It might help if you show exactly what values you have tried. This works for me: py> volume = 1.23456789 py> print(volume ) 1.23456789 py> print(round(volume , 2)) 1.23 The rest of your code is interesting but irrelevant to your question. If you want to learn how to round to 2 decimal places, the actual calculation of surface area and volume aren't necessary. The only really important part is this line: > print("A cone with radius", r, "\nand height of", h, "\nhas a volume of : > ", volume, "\nand surface area of : ", surfacearea,) and even that can be cut down to just: volume = 2345.987654321 # for example print(volume) We can round the result first, then print it: print(round(volume, 2)) or we can change the display by using string formatting: print("%.2f" % volume) print("{:.2f}".format(volume)) -- Steve “Cheer up,” they said, “things could be worse.” So I cheered up, and sure enough, things got worse. -- https://mail.python.org/mailman/listinfo/python-list
