Prime numbers

Could someone explain to me in python how I could write a code that returns the prime number between two numbers?

Suppose you want to find prime numbers between 1 and 10 So it should be a=1 b=10 for i in range((a+1),b): if i%2!=0 and i%3!=0 or i/2==1 or i/3==1: print(i)

just edit the code above, start with input, like a=input() b=a//2 # actually forgot the notation, but basically works like 25//2=12, it's the partner of modulo prime=0 if a=2 or a=3: print('prime') elif a<2: print('not prime') else: for i in range (2, b): if a%i=0 print('prime') prime=1 break if prime=0: print('not prime')
