# Python program to right rotate a list by n

In this article, we will see how to right rotate a list from the given rotation number. A list has comma-separated values (items) between square brackets. Important thing about a list is that the items in a list need not be of the same type

Let’s say the following is our input list −

myList = [5, 20, 34, 67, 89, 94, 98, 110]


The following is the output with n = 4 −

89, 94, 98, 110, 5, 20, 34, 67


## Right rotate a list by n using slicing

Here, slicing is used to right rotate a list −

### Example

# Create a List
myList =[5, 20, 34, 67, 89, 94, 98, 110]

print("List before rotation = ",myList)
# The value of n for rotation position
n = 4

# Rotating the List
myList = (myList[len(myList) - n:len(myList)] + myList[0:len(myList) - n])

# Display the Update List after rotation
print("Updated List after rotation = ",myList)


### Output

List before rotation =  [5, 20, 34, 67, 89, 94, 98, 110]
Updated List after rotation =  [89, 94, 98, 110, 5, 20, 34, 67]


## Right Rotate a List by n with if

Here, the if statement is used to right rotate a list −

### Example

# Create a List
myList =[5, 20, 34, 67, 89, 94, 98, 110]

print("List before rotation = ",myList)

# The value of n for rotation position
n = 4

# Rotating the List
if n>len(myList):
n = int(n%len(myList))
myList = (myList[-n:] + myList[:-n])

# Display the Update List after rotation
print("Updated List after rotation = ",myList)


### Output

List before rotation =  [5, 20, 34, 67, 89, 94, 98, 110]
Updated List after rotation =  [89, 94, 98, 110, 5, 20, 34, 67]


## Right Rotate a List by n with for loop

Here, the for loop is used to right rotate a list −

### Example

# The value of n for rotation position
num = 4

# Create a List
myList =[5, 20, 34, 67, 89, 94, 98, 110]

print("List before rotation = ",myList)

newlist = []

for item in range(len(myList) - num, len(myList)): newlist.append(myList[item])
for item in range(0, len(myList) - num): newlist.append(myList[item])

# Display the Update List after rotation
print("Updated List after rotation = ",newlist)


### Output

List before rotation =  [5, 20, 34, 67, 89, 94, 98, 110]
Updated List after rotation =  [89, 94, 98, 110, 5, 20, 34, 67]
