About This prime detector is made based on the Algorithm.txt file that I added in prime_1 repository. This is my first python project in University and I decided to share with you. Using Guide For using code you have to inter your number after main.py in terminal or console with space between like: main.py <your number> => main.py 13 => The output is 'Number is prime' or like: main.py 10 => THe output is 'Number is NOT prime' *Notice* This code is NOT efficient to calculate big numbers. I highly don't recommend using this to calculating big numbers Instead you can use is_prime function in Numpy package that is more efficient. I hope this will be helpful for you. Have a great day
