Description

def f(x,y,z):

Defines a user-defined function with function name f, and arguments

x, y, and z.

if x>0: If variable x is greater than 0,

t=x+y+z defines variable t as the execution result of x+y+z.

else: Otherwise (if variable x is 0 or less),

t=x-y-z defines variable t as the execution result of x-y-z.

return(t) Makes variable t the return value.

Running this py script as a standalone script will only define the user defined function. The

function will not be executed so the py script will end without output.

Execution Result

Sample 4: Importing a py File

Purpose

import can be used to import py files into other py files and

run the processes written in the imported py files.

This makes it possible to use user-defined functions and

variables across multiple py files.

Use the syntax below for execution of a module function or

variable.

Description

import userfunc Imports userfunc.py and runs the written process.

a=userfunc.f(1,2,3)

Inputs arguments 1, 2, and 3 to the user defined function f defined by

userfunc.py, executes the function f, and defines variable a as the result

value.

print(a) Outputs the value stored in the variable a.
