1. Reverse a String: Write a function that takes a string as input and returns the reverse of that string.

#Qn.1 reverse a string
def reverseString (text):
    return text[::-1]
reverseString ('hello world')

'dlrow olleh'

2. Palindrome Checker: Write a function that takes a string as input and returns True if it’s a palindrome (reads the same forwards and backwards), False otherwise.

#Qn.2 Palindrome Checker
def isPalindrome (text):
    return text == text[::-1]
isPalindrome('madam')

True

3. Factorial Calculator: Write a function that calculates the factorial of a given number. The factorial of a non-negative integer is the product of all positive integers less than or equal to the integer.

#Qn.3 Factorial Calculator
def numberFactorial(number):
    if number==0 or number==1:
        print(1)
    else:
        factorial = 1
        for value in range (1, number+1):
            factorial *= value
        print(factorial)
numberFactorial(6)

4. Fibonacci Sequence: Write a function to generate the Fibonacci sequence up to a certain number of terms. The Fibonacci sequence is a series of numbers where each number is the sum of the two preceding ones, usually starting with 0 and 1.

#Qn.4 Fibonacci Sequence
def fibonacciSequence (number):
    sequence = [0,1]
    while len (sequence)< number:
        sequence.append(sequence[-1] + sequence[-2])
    return sequence
fibonacciSequence (8)

[0, 1, 1, 2, 3, 5, 8, 13]

5. Prime Number Checker: Write a function that checks if a given number is prime.

#Qn.5 Prime Number Checker
def isPrimeNumber (number):
    if number <= 1:
        return False
    for value in range(2,int(number**0.5)+1):
        if number % value == 0:
            return False
    return True
isPrimeNumber(4)

False

6. List Reversal: Write a function that reverses a list.

#Qn.6 List Reversal
def reverseList(list_):
    return list_[::-1]
reverseList([1,3,5,6,8])

[8, 6, 5, 3, 1]

7. List Sorting: Write a function that sorts a list of integers in ascending order without using Python’s built-in sorting functions.

#Qn.7 List Sorting
def sortList(list_):
    return sorted(list_)
sortList([3,7,1,9,2])

[1, 2, 3, 7, 9]

8. Anagram Checker: Write a function that takes two strings as input and returns True if they are anagrams (contain the same letters with the same frequency), False otherwise.

#Qn.8 Anagram Checker
def areAnagram(string1, string2):
    return sorted(string1) == sorted(string2)
areAnagram('listen','silent')

True

9. Count Words in a String: Write a function that takes a string as input and returns the count of words in that string.

#Qn.9 Count words in a String
def countWords(string):
    return len(string.split())
countWords('hello world')

2

10. Unique Elements: Write a function that takes a list and returns a new list with only the unique elements from the original list.

#Qn.10 Unique Elements
def uniqueElements(list_):
    return list(set(list_))
uniqueElements([2,4,3,2,6,4,7,9,5,3,5,1,6])

[1, 2, 3, 4, 5, 6, 7, 9]
