4 = If a is [1, 2, 3]
(a)what is the difference (if any) between a * 3 and [a, a, a]?
(b) is a * 3 equivalent to a + a + a?
(c) what is the meaning of a[1 : 1 ] = 9 ?
(d) what's the difference between a[1:2] 4 and a[1:1]
Answer =
a =
a * 3 means that it have 3 time of value a in one list, while [a, a, a] is form nested list.
b =
Yes
c =
a[1:1] = 9
first of all it give error it mean that we are trying to assign a non sequence value to the list slice, such as number.
d =
a[1:2 ] = 4 it means that value 4 put at index number 1, but in a [1:1 ] = 4 it means that there is no index number where that value can be put in the list, but both will give error because they are non sequnce value.
