I am confused about how relational operators in computer programming are different to those in maths. This is a very basic question but I am only just getting started with programming as a major beginner.
See the following statement:
if weight <= 2:
price_per_pound = 1.50
elif weight <= 6:
price_per_pound = 3.00
elif weight <= 10:
price_per_pound = 4.00
price_per_pound = 4.75
My question is this. Say weight = 4.
4 is less than 6, but it is also less than 10.
So weight = 4 works for the idea that weight <= 6, but weight 4 can also work for the idea that weight <= 10.
From using this if/elif/else statement in a programme, I have learned that if I passed in weight = 4, this would apply to the weight <= 6 statement, and price_per_pound would equal 3.00.
Why does weight = 4 fall into the weight <= 6 category only? Why can’t it also have been equal to weight <= 10?
