I’m new to Python and programming altogether. As I’m going through my first few online lessons, I’m trying to add text to the users weight i.e. 70kg’s

My code that works is as follows:

weight_lbs = input(“Please enter your weight in pounds? “)

weight_kg = int(weight_lbs) * 0.45

print(weight_kg)

Nb: the above code works but does not display the text “kg’s” after the number.

I’ve tried: print(weight_kg) + “kg’s” or print(weight_kg + “kg’s”) or print(weight_kg), “kg’s”

Unfortunately I keep getting error, unsupported operand type(s) for +: ‘NoneType’ and ‘Str’

Thanks in advance

Mark

  • @wwii no, that's definitely the wrong one here. – Karl Knechtel Sep 09 '22 at 07:38

print(f"{weight_kg}kg's")

or simply 

print(str(weight_kg)+"kg's")

  • Thank you so much. The second one definitely did the trick. Did not quite understand the syntax in the first one though but that’s okay..I’ll remember the second solution going forward – Van Wilder Jun 09 '20 at 08:00
