DAVID MPHANDE range(5) returns [0, 1, 2, 3, 4] So now get cubes of these values.

DAVID MPHANDE In python there are 3 range function which accept different parameters #if you dont provide end value #by default range will give value from 0 to exclude end value #exclude means end value will not be consider print(list(range(5))) #[0, 1, 2, 3, 4] ------------------- #range(start, end) #default step is 1 print(list(range(0, 5))) #[0, 1, 2, 3, 4] -------------------- #range(start, end, step) print(list(range(0, 50, 5))) #[0, 5, 10, 15, 20, 25, 30, 40, 45]

Your syntax is like range(start, stop, step) So it takes step of 5 numbers that's why 0,5,10,... So on. Also, In python the loop stop at stop but it does not include the number that's why loop doesn't include 50 at last

I get it...... range(5) returns [0, 1, 2, 3, 4] 0 ** 3, 1 ** 3, 2 ** 3, 3 ** 3, 4 ** 3 0 1 8 27 64 print([0 ** 3, 1 ** 3, 2 ** 3, 3 ** 3, 4 ** 3]) Output: [0, 1, 8, 27, 64]

What do you think caused these numbers? More specifically: what values of i can cause these outputs?

By default index starts from 0, given range 5 it will follow the loop of 0 to 4 ie. 0,1,2,3,4. And your logic i**3 asking it to produce cubes so. Loop will work as 0**3= 0 1**3= 1 2**3= 8 3**3= 27 4**3= 64

A͢J here why it skips 5 numbers. print(list(range(0, 50, 5))) #[0, 5, 10, 15, 20, 25, 30, 40, 45]
