-# LAB_FUNCTIONS_102
-
-## Create a function : find_primes that takes in 2 parameters of type int , and print the prime numbers between the first parameter and the second parameter . 
-
-### hint
-a prime number i a number that is divisible only by itself and 1 (e.g. 2, 3, 5, 7, 11)    
-Also , you can think of it as A Prime Number is a number that cannot be made by multiplying other whole numbers
-
-
-#### for example, primes between `25` and `50` are:
-```
-29   
-31   
-37   
-41   
-43   
-47   
-```
-
-# Bonus
-## write a function that takes a string as a parameter
-- first check that the type of the parameter is of type str
-- then, it should separates the word at any capital letter and replace it with a small letter 
-- and  should return the new modified string !
-
-Example: `helloWorldThere` should return :
-```hello world there```
