The function max$()$ is built into Python. However, if we were to write it ourselves, it could look something like this:

def max$($a$,$b$)$:

$"""$

a$,$ b: int$/$float

Returns: max of a and b

$>>>$ max$(9,55)$

$55$

$"""$

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$)$
