PYTHON: Any positive integer greater than $1$ can be expressed as the product of a series of prime numbers. Such a decomposition is unique and is called prime factorization. For example, $60$ can be decomposed into $2*2*3*5.$ Write a function to perform prime factorization on an integer and return the prime factorization formula. Write a main program, input an integer greater than $1,$ call the function to perform prime factorization, and display the result. Main function example: n$=$int$($input$())$ print$($primefactor$($n$))$ Input format: an integer $($greater than $1)$ Output format: integer $=$ multiplication of prime factors. Sample input: $60$ Output sample: $60=2*2*3*5$
