Python | Reverse slicing a given string

Michael Zippo 18.07.2021

Method # 1: Using join () + reversed ()
A combination of the above function can be used to accomplish this particular task. In this, we flip the string in memory and attach to the sliced number. characters to return the line cut from the trailing end.

# Python3 code to demonstrate how it works
# Reverse slicing line
# Using join () + reversed ()

# initialization string

test_str = "GeeksforGeeks"

# print original string

print ( " The original string is: " + test_str)

# initialize K

   K   =   7  
   
  # Using join () + reversed ()  
  # Reverse slicing line  
   res   =   ’’ .join (  reversed   (test_str [  0  : K])) 
   
  # print result  
   print   (  "The reversed sliced string is:"   +   res)

Output:

 The original string is: Python.Engineering The reversed sliced string is: ofskeeG

Method # 2: Use Using line slicing
Line slicing can be used to accomplish this particular task by using "-1" as the third argument when slicing, we can force the function to do the slicing from the back, hence it would be a simple solution .

# Python3 code to demonstrate how it works
# Reverse slicing line
# Using line slicing

# initialization string

test_str = " Python.Engineering "

# print original line

print ( "The original string is:" + test_str)

# initialization K

K = 7

# Using line slicing
# Reverse slicing line

res = test_str [(K - 1 ) :: - 1 ]

# print result

print ( "The reversed sliced string is: " + res)

Output:

 The original string is: Python.Engineering The reversed sliced string is: ofskeeG
