W4_A1_ Ex-5_Dimension mismatch

followed instructions but got mismatch error, need help, i passed all tests on the 4 previous, this one is based on the previous ones but something is not working

Why are you dividing L by 2 in the str() functions there? Please see this thread for the “dimensional analysis” on that test case.

Thank you Paul, that was the mistake, it works fine now
