Question

evens=[range(i) for i in range(10) if i**2 % 2 == 0]

print(evens)

result: [range(0,2) ,.....so on]

Answer 1

In python, there is no difference between giving the start point as a parameter to the range function, or not. It usually comes down to developer himself. You can test these codes in the code playground, which gives you a possibility to figure out and understand all these concepts without external support.
