The function

is built into Python. However, if we were to write it ourselves, it could look something like this:

def $ma{x}_{n\text{'}\text{'}}(a,b)$ :

$a,b$ : int$/$float

Returns: max of a and $b55$

$"""$

maximum $=a$

if $(b>a)$ :

maximum $=b$

return maximum

The environment diagram below was generated by executing the following statements:

$a=12$

$b=8$

$c=$max$(b,a)$
