  • you also maybe want to think about do you want int or float. Int is a whole number so for height you could be 1m or 2m. If you want to be 1.73m then you need to use floats – Chris Doyle Feb 26 '21 at 14:27

Simply add "int" infront of where you are asking for inputs, like so:

inp_name = str(input('Please input your name - '))
print('Welcome', inp_name)
inp_height = int(input('Please input your height in metre - '))
inp_weight = int(input('Please input your weight in kg - '))
print(inp_name, ', your bmi is :')
bmi = int(inp_weight)/(int(inp_height) ** 2)
print(bmi)

You can see that I have also added str on the first line, this will make it so the user can only input a string. You can also ask for a float by adding float, like this: float(input("Input a float: ")).

EDIT: Furthermore, if a user doesn't input the data type you are asking for, an error will occur:

enter image description here

You can stop this error by adding a "try: except:":

try:
    inp_height = int(input("Please input your height in metres: "))
    print(inp_height)

except: 
    print("Enter the correct data type")

This will catch any errors that happen.

    Putting `str(...)` around `input(...)` accomplishes nothing. `input` always returns a string. – khelwood Feb 26 '21 at 16:54
  • @khelwood Ah okay! I honestly thought this but I thought it was best practice just to use str() when you want a string input. I guess you can use "if variable str:" to accept strings as inputs. Thank you for your comment though, always good to learn these things! – Insula Feb 26 '21 at 20:40
