Python TypeError when dividing a raw input variable by a number

Question

I want to convert an entered lb weight to kg and I get the following error...

TypeError: unsupported operand type(s) for /: \'unicode\' and \'float\'<

Answer 1

That's because with raw_input, the input is raw, meaning a string:

lbweight = float(raw_input("Current Weight (lb): ") )

kgweight = lbweight/2.20462
