Examples of Dip Code (in Python)

## Factorial function
def factorial(term):
    fact = 1
    if term >= 1:
        for i in range(1, term + 1):
            fact = fact * i
    print(fact)

## Fibonnaci Function
def fib(nterms):
    n1 = 0
    n2 = 1
    count = 0

    if nterms <= 0: print("Input positive integer")
    if nterms == 1:
        print("Fibonnaci sequence upto" + " 1" + ":")
        print(n1)
    else:
        print("Fibonacci sequence:")
        while count < nterms:
            print(n1)
            nth = n1 + n2
            n1 = n2
            n2 = nth
            count = count + 1

## Hello World in Python
print("Hello, world!")

## Random
from random import randint
def random(list_):
    random_number = randint(0, len(list_) - 1)
    return(list_[random_number])

## Math Functions
# Squares a value
square = lambda num: num**2

# Checks if a number is even or odd
def odd_or_even(number):
    if number % 2 == 0:
        print("even")
    else:
        print("odd")

## Examples
fib(4)
factorial(4)
print(square(4))
print(random([1, 2, 3, 4]))
odd_or_even(4)

## Caesar Cipher in Python
alphabet = "abcdefghijklmnopqrstuvwxyz "
plaintext = input("Which word / phrase would you like to encrypt: ")
key = int(input("What would you like the key to be? "))
ciphertext = ""

for character in range(0, len(plaintext)):
    for letter in range(0, len(alphabet)):
        if plaintext[character] == alphabet[letter]:
            if plaintext[character] != " ":
                index = letter + key
                ciphertext = ciphertext + alphabet[index % 26]
            else:
                ciphertext = ciphertext + " "

print("ciphertext: " + ciphertext)
