In the UK, 'practice' is a noun (like preparation), but 'practise' is a verb (like to prepare). The difference between practice and practise only affects those following British writing conventions. If you're following US convention, use 'practice' for everything.

As a verb, in American English, “practice” means to perform something habitually or regularly: It’s time to practice playing piano. In UK and Australian English, “practise” is the spelling used for the verb form: Let’s practise for the recital together.

In British English, practice is the noun and practise is the verb, whereas in American English, practice is used for both. By practising (pun intended!) the correct use of these words, you’ll ensure that your writing remains clear and accurate.

In British English, practice is a noun, and practise is a verb. The same logic applies to Australian and New Zealand dialects. According to the Oxford Canadian Dictionary, both practice and practise are acceptable as both a verb and a noun.

Practise and practice are two spellings of the same verb meaning “engage in something professionally” or “train by repetition.” The spelling depends on whether you’re using American or British English. Practice is also used as a noun meaning “training” or “the application of a method.”
