1. Example: Using the Dummy Python Package

Demomstration

This example demonstrates how to use the dummy Python package located in lib/py_pkg.

from py_pkg import math_utils, string_utils, module

# Math utilities
print("PI:", math_utils.PI)
print("Square of 4:", math_utils.square(4))

calc = math_utils.Calculator()
print("Add:", calc.add(2, 3))
print("Divide:", calc.divide(10, 2))

# String utilities
print(string_utils.DEFAULT_GREETING)
print(string_utils.shout("hello world"))

fmt = string_utils.Formatter()
print(fmt.surround("example", "#"))

Output Explanation

When you run this code, you will see output similar to:

PI: 3.14159
Square of 4: 16
Add: 5
Divide: 5.0
Hello
HELLO WORLD
#example#

  • PI: 3.14159 prints the value of math_utils.PI.

  • Square of 4: 16 is the result of math_utils.square(4).

  • Add: 5 is the result of calc.add(2, 3).

  • Divide: 5.0 is the result of calc.divide(10, 2).

  • Hello is the value of string_utils.DEFAULT_GREETING.

  • HELLO WORLD is the result of string_utils.shout("hello world").

  • #example# is the result of fmt.surround("example", "#").
