BMI Calculator line 9: invalid syntaxis

Question

Tracking your BMI is a useful way of checking if you’re maintaining a healthy weight. It’s calculated using a person's weight and height, using this formula: weight / height²

The resulting number indicates one of the following categories:
Underweight = less than 18.5
Normal = more or equal to 18.5 and less than 25
Overweight = more or equal to 25 and less than 30
Obesity = 30 or more

Let’s make finding out your BMI quicker and easier, by creating a program that takes a person's weight and height as input and outputs the corresponding BMI category.

Sample Input
85
1.9

Sample Output
Normal

weight = int(input())
height = int(input())

BMI = weight / height**2

if BMI < 18.5:
print("Underweight")

if BMI =< 18.5 and BMI < 25:
print("Normal")

if BMI =< 25 and BMI < 30:
print("Overweight")

if BMI =< 30:
print("Obesity")

what's wrong again?

Answer 1

=< is incorrect syntax
<= is correct syntax.

You might wish to use elif and else also

Answer 2

Rik Wittkopp, Alright, I will make sure to do so, thanks
