Question

Write a program in PYTHON that takes a string and an integer as inputs from the user, and then prints a

new string that contains the letters from the original string “rotated” by the given amount.

For example, “cheer” rotated by 7 places gives the word “jolly” and “melon” rotated by -10 gives the word “cubed.”

Use built-in function: ord() to convert a character to a numeric code and chr() to convert numeric code to character.

Answer 1

def String_rotation(word, integer):
rotated_string = ''
#it will store the ASCII value of 'a' in start_limit
start_limit = ord("a")
# it will store the ASCII value of 'z' in end_limit
end_limit = ord("z")
for w in word:
char_num = ord(w) + integer
#adjustments of a character
while char_num > end_limit: char_num -= 26
while char_num < start_limit: char_num += 26
#converting an integer to character
w = chr(char_num)
rotated_string = rotated_string + w
return (rotated_string)

word =input("Enter a string for the rotation: ")
integer= int(input("Enter an integer to rotate the given string by the integer: "))
print (String_rotation(word,integer))

Output is as follows:
