String slicing in Python to rotate a string

A string is given, our task is to slicing the string into two way. One is clockwise and another anticlockwise.

1. Left (Or anticlockwise) rotate the given string by d elements (where d <= n).

2. Right (Or clockwise) rotate the given string by d elements (where d <= n).

Example

Input: string = "pythonprogram" d = 2 Output: Left Rotation: thonprogrampy Right Rotation: ampythonprogr

Algorithm

Step 1: Enter string. Step 2: Separate string in two parts first & second, for Left rotation Lfirst = str[0 : d] and Lsecond = str[d :]. For Right rotation Rfirst = str[0 : len(str)-d] and Rsecond = str[len(str)-d : ]. Step 3: Now concatenate these two parts second + first accordingly.

Example Code

def rotate(input,d):    # Slice string in two parts for left and right    Lfirst = input[0 : d]    Lsecond = input[d :]    Rfirst = input[0 : len(input)-d]    Rsecond = input[len(input)-d : ]    print ("Left Rotation : ", (Lsecond + Lfirst) )       print ("Right Rotation : ", (Rsecond + Rfirst) )       # Driver program    if __name__ == "__main__":       str = input("Enter String ::>") d=2 rotate(str,d)

Output

Enter String ::> pythonprogram Left Rotation: thonprogrampy Right Rotation: ampythonprogr
