Answer 1

def isPrime(x):
if x < 2: # number lessthan 2 , not prime
return False
elif x == 2: #number 2 prime
return True
for n in range(2, x): # from 2,x if it is divisable by any number n , then its not prime
if x % n ==0:
return False
return True

def primeGenerator(a, b):
#your code goes here
for number in range(a,b): #loop runs from a,b-1 values
if isPrime(number): # if number is prime
yield number # returns number to call
f = int(input()) #input
t = int(input())

#call the function primeGenerator with parameters f,t inputs , convert the returns values into list and display list
print(list(primeGenerator(f, t)))

# return causes to come out of function. where as yeild return value and continue execute next instruction..
hope it helps..

Thank you very much i appreciate
but can u tell me what the 'return True' at the end of the 'isprime' function stands for..

Answer 3

If non of if condition is true then it does not return a value. You need to return true if number is not < 2, not equal to 2, and also not evenly divisable by 2, n-1.
Take ex: 7,
It is not less than 2, not equal to 2, not divisable by 2, to 7-1 so all if conditions you have are failed. It means it prime so should return true. That's what does by return true and end. Hope it clears..
