I need help with this bmi code. This is made in Python.

Question

So it works fine if i dont have the user input but if i do in line 4 it says error
Unsupported operand types for ** or pow(): 'str' and 'int'
This is line 4 bmi = weight_kg / (height_m ** 2
Heres the code
name = input("please enter your name")
height_m = input("please enter your height in meters")
weight_kg = input("please enter your weight in kg")
bmi = weight_kg / (height_m ** 2)
print( "bmi: ")
if bmi < 25:
print(name)
print("is not overweight")
else:
print(name)
print("is overweight")

Answer 1

Actually your output is in string format and +,-,÷,* and ** don't work string format variable so you need to convert into int or may be into float like this.

weight_kg=int(input("please enter your weight in kg"))

Answer 2

You need to convert the variable to integer type first,
use this :
name = int(input())
height = int(input())
weight = int(input())
