Write a Python function that when executed, asks the user to enter an integer number, then the function gives out the number of prime numbers that are smaller than the input integer number. Here is the answer to this question using only the knowledge of recursive functions and if-blocks, def isPrime(n):        isPrime =True        def is_divisible(n,divisor):          if n<(divisor-1)*divisor: return False          if n%divisor==0: return True  else:       divisor +=1  return is_divisible(n,divisor)  if n==2:     isPrime =True    elif is_divisible(n,divisor=2):          isPrime =False      return isPrime   def getNumPrimes(n):      if n <=2:        return0     else:      return isPrime(n-1)+ getNumPrimes(n-1) getNumPrimes(13) 5 (A) Now rewrite getNumPrimes(n) and the other functions in the above code using for-loop this time. Name the new functions get_prime_for(n) and isPrime_for(n), with for in the names indicating that the functions now use for-loops.

Computational Systems

The computation systems can be defined as the systems that are capable of solving a problem that includes calculations either mathematical or logical, and are able to produce the result as an output. For example, a simple calculator that is given a set of numbers and operators as input and produces the result as an output can be defined as a computational system. The above example is a simple illustration only, the computational systems range from simple devices to complex devices such as the systems that control the SpaceX companies, Starlink satellites which are being quite recently seen in the skies at many places globally.
