Hi, I am taking a class in order to learn Python. One of the exercises I need
to do is write function definitions. I cannot figure out how to do one of them.
To show you an example here is a similar problem:
If m is an integer, then isPrime(m) iff m is prime.The code:
# Prompts the user for an integer m and then computes and prints whether# m is
prime or not.
# isPrime(m): I -> Bool# If m is an integer, then isPrime(m) if and only if m
is prime.def isPrime(m): return False if m <= 1 else isPrimeItr(1,0,m)
# isPrimeItr(i,a,m): I x I x I -> Booldef isPrimeItr(i,a,m): return False if
a> 2 else True if a == 2 and i == m +1 else isPrimeItr(i+1,a+1,m) if m % i == 0
else isPrimeItr(i+1,a,m)
# print a brief description of the program followed by an empty
lineprint("Computing Prime Numbers")print("Prompts the user an integer value
for m and then computes and")print("prints if m is prime or not.")print()
# prompt the user for a value for mm = eval(input("Enter an integer value for
m: "))
# print if m is primeprint("The value that", m, "is a prime integer is",
isPrime(m))
------------------------------------------------------------------------------------------------------------------------
These are the problems I am having problem with:
If m and n are integers, then anyPrimes(m,n) iff there are any prime numbers in
the interval [m,n).
If m and n are integers, then countPrimes(m,n) is the number of prime numbers
in the interval [m,n).
If anyone could help that would be great. Thank you.
