You can turn a list into function arguments using *:

def f(a,b,c): print a, b, c
x = [1,2,3]
f(*x)
f(*(1,2,3))

You can compose classes using import. Here’s a method that can be reused by multiple classes:
```
# PythonForProgrammers/utility.py
```
def f(self): print “utility.f()!!!”

Here’s how you compose that method into a class:

# PythonForProgrammers/compose.py
class Compose:
     from utility import f

Compose().f()
