Hi all,

I am wondering what is the difference between

divide_by_two = [num/2 for num in nums]
divide_by_two = [num/2.0 for num in nums]

they return the same result when I run the codes.

My result is difference as below:

nums = [4, 8, 15, 16, 23, 42]
divide_by_two = [num/2 for num in nums]
print(divide_by_two)
[2, 4, 7, 8, 11, 21]

nums = [4, 8, 15, 16, 23, 42]
divide_by_two = [num/2.0 for num in nums]
print(divide_by_two)
[2.0, 4.0, 7.5, 8.0, 11.5, 21.0]

I’m not sure the result is caused by version of python or not.

i think you can use divide by 2 if you want whole number, you can use 2.0 if you want your result as a decimal number
