[Tutor] error message questions

[adam urbas]

Hello all,I was wondering if there would be someone who would be able to give me a list of error messages and their meanings.  I've attached this test.py to illustrate my problem.  When I run the program, I am able to enter all the data, yet it will not calculate.It says:can't multiply sequence by non-int of type 'str'I really would like to know how to fix this.I get a similar message with my other one, radiacir.py:can't multiply sequence by non-int of type 'float'Please help!Thanks in advance,Adam
