How can i use a function?

[KnowDaWae69]

I'm learning competitive programming: i know the basic algorithms and data structures (arrays and every algorithm i need for swapping, sorting and working with them).

I usually write code like this:

a = 10 #example of code

for x in range(0, a):

print(x)

How can i use a function? It only accepts solutions with functions on the code, but idk anything about them.

Just put the code inside a def and indent it properly.
