Hi, I am trying to rotate list of 3 to left
for this I am trying to define this function
def rotate_left3(nums)

#argument nums is list
for example
rotate_left3([1, 2, 3])
I am expecting value [2,3,1] in return. I have written the following code
    a = nums
    a[0]=nums[1]
    a[1]=nums[2]
    a[2]=nums[0]
    return a #this is returning [2,3,2] instead of [2,3,1]
however if I assign
a = [0,0,0] #or any other value other than directly assigning nums
the code works perfectly
