Q.1

def rotate(string, increment):
    result = ""
    for i in string:
        if (i != " "):
            ch1 = ord(i)
            ch1 += increment
            ch1 = chr(ch1)
            result += ch1
    return result


string = input("Enter the string for rotation:")
increment = int(input('Enter the increment number:'))

result = rotate(string, increment)
            
print(f'The original string {string} after rotation by {increment} is {result}.')

Q.2

def chrToString(chrLst):
    result = ""
    for i in chrLst:
        result += i
    return result

n = int(input("How many characters you want in your list:"))
chrLst = []
for i in range(n):
    char = input('Enter the character:')
    if(len(char) == 1):
        chrLst.append(char)
    else:
        print('Enter a single character not a string.')

result = chrToString(chrLst)
print(result)

Q. 3

def findIndex(lst, reqElmnt):
    return lst.index(reqElmnt)

lst = ["cat", "dog", "elephant", "horse", "rabbit", "cow"]
reqElmnt = input('Enter the element you want the index of:')
print(f'The index of {reqElmnt} in the list is: {findIndex(lst, reqElmnt)}')
