Why does the last line return [0]?

Question

squares = [0, 1, 4, 9, 16, 25, 36, 49, 64, 81]
print(squares[2:6])
print(squares[3:8])
print(squares[0:1])

Answer 1

When slicing list, the start index (in your case 0) is inclusive and the end number (in your case 1) is exclusive. Therefore it only gets index 0.

Examples...

l= [1,2,3,4,5]

l[0:3] #Equals 1,2,3
l[2:4] # Equals 3, 4
