Whenever I executed the code I get wrong answers only. I try for 2 numbers 55 and 89 and I get same answer for both no matter how I alter the code.
I know it's a dumb question but I tried a lot of ways but it doesn't work. I guess it's some kind of indentation problem. For me it's a bit hard to get into python because of no use of brackets so please help this noob. Thank you
a=int(input("Enter the number you want to check for prime: \n"))
b = False
for i in (2,a):
if(a%i)==0:
b = True
break
i=i+1
if b:
print("The number is not a prime number")
else:
print("The number is a prime number")
Ok, so your error is not a code error. Your algorithm is incorrect. For any given number you do 2 checks:
This does not say anything about it being a prime number. This is probably a homework assignment so I will not give you a working solution here, but I think that this should help you on your way.
Ok maybe I see something else: your loop for i in (2,a)
and later on i=i+1
does not do what you think it does.
You can verify this by adding a statement print(i)
in your code. And look at the range function, this might help you out.
