Can you provide a code to print all possible rotations of a given Array and the other steps required given the following:
Print all possible rotations of a given Array | Function to reverse array between indices s and e.
Function to generate all possible rotations of array.
Driver Code"
How can the above be solved in Python?

#Here is code to print all possible rotations of a given Array and the other steps required.
 def reverse ( arr , s , e ) :
	while s < e :
		tem = arr [ s ]
		arr [ s ] = arr [ e ]
		arr [ e ] = tem
		s = s + 1
		e = e - 1
def fun ( arr , k ) :
	n = len ( arr ) - 1
	v = n - k
	if v >= 0 :
		reverse ( arr , 0 , v )
		reverse ( arr , v + 1 , n )
		reverse ( arr , 0 , n )
		return arr
arr = [ 1 , 2 , 3 , 4 ]
for i in range ( 0 , len ( arr ) ) :
	count = 0
	p = fun ( arr , i )
	print ( p , end = " ▁ " )
