Examples of reverse() method in Python

# alphabets list
alphabets = ['a', 'b', 'c', 'd', 'e', 'f']

alphabets.reverse()

Updated List: ['f', 'e', 'd', 'c', 'b', 'a']

# alphabets list
alphabets = ['a', 'b', 'c', 'd', 'e', 'f']
print('Original List:', alphabets)

# Reversing a list 
#Syntax: reverselist = alphabets[start:stop:step] 
reverselist = alphabets[::-1]

# updated list
print('Updated List:', reverselist)
 

Output:

Original List: ['a', 'b', 'c', 'd', 'e', 'f']
