There's a difference in US English and UK English Practice is the Noun for both US and UK While Practise is the verb in UK and Practice is the verb in US Using "practice" all the time will be correct either way, so you might as well ignore "practise" completely

practice is a noun practise is a verb

The difference between using "practice" and "practise" for me is one is American English and the other is British English. Of course from the above answers, I was surprised to learn that British English uses both spellings. There are other spelling patterns that are different between American English and British English, such as "realize/realise," "center/centre," "dreamed/dreamt," and "favorite/favourite."

we use practise as a verb，however，practice as a noun，both they have the same meaning mean ‘a regular trainning or exercise that you do in order to improve your skill at some area’

Laurynas is correct.
