- Modules allow direct manipulation of hardware components connected to the computer.
- Modules bypass Python's interpreter to execute code directly in the operating system kernel.
- Modules facilitate code reusability and organization by logically grouping related functions and classes. (correct)
- Modules automatically optimize code execution speed without requiring explicit optimization techniques.

Modules and Libraries
- A module is a file containing Python code, which can include functions and classes.
- Using modules helps logically organize Python code.
- Modules make code easier to understand and use.
- Any Python source file can be used as a module by using the import statement in another Python source file.
- Import statements include
import moduleName as moduleAlias,from moduleName import functionName, andimport moduleName.
Creating and Accessing Modules
- To create a module, save Python code in a
.pyfile (e.g.,greetings.py). - To access a module, use the
importstatement (e.g.,import greetings). - Module contents can be accessed using dot notation (e.g.,
greetings.greet()). - When using modules, ensure that the main script and the module files are in the same project.
Calculator App Example
- A calculator app can use separate modules for each operation like addition, subtraction, multiplication, and division.
- Create a module named
operation.pywith functions for add, subtract, multiply, and divide.
Problem Set 1: Salary Computation App
- Create a Salary Computation App using three modules:
GrossSalary.py,SalaryDeductions.py, andNetSalary.py. - GrossSalary.py computes the gross salary based on user inputs such as name, hours worked, and a fixed hourly rate of Php 500.00/hr.
- SalaryDeductions.py computes deductions.
- NetSalary.py computes the net salary.
- Tax is fixed at 12% of the gross salary.
Problem Set 2: Name Generator App
- Create a Name Generator App.
- Use three lists for first name, middle name, and last name, each containing 10 items.
- Randomly select items from each list to generate a new name.
- Display the generated name with a congratulatory message.
- If the user chooses not to generate a new name, display a thank you message and show all previously generated names.
Built-In Modules
- Built-in modules are written in C and interpreted using the Python interpreter.
- To view all built-in modules, use
help('modules'). - Some built-in modules include math, random, and datetime.
Random Module
- The Random module implements pseudo-random number generators for various distributions.
random.randrange(myNum, myRange)function returns a randomly selected element from the specified range.random.shuffle(prizes)can be used to shuffle the order of elements in a list.
DateTime Module
- This module is used to work with dates as date objects.
datetime.datetime.now()function returns the current date and time.x.yearreturns the year value.x.strftime("%A")returns the weekday's full name.datetime.datetime(2020, 5, 17)creates a specific date (year, month, day).
String Placeholders for strftime() Method
- These placeholders define how date and time components are formatted in strings.
%a: Weekday, short version (e.g., Wed).%A: Weekday, full version (e.g., Wednesday).%w: Weekday as a number (0-6, 0 is Sunday).%d: Day of the month (01-31).%b: Month name, short version (e.g., Dec).%B: Month name, full version (e.g., December).%m: Month as a number (01-12).%y: Year, short version, without century.%Y: Year, full version.%H: Hour (00-23).%I: Hour (00-12).%p: AM/PM.%M: Minute (00-59).%S: Second (00-59).%f: Microsecond (000000-999999).%z: UTC offset.%Z: Timezone.%j: Day number of year (001-366).%U: Week number of year, Sunday as the first day of week (00-53).%W: Week number of year, Monday as the first day of week (00-53).%c: Local version of date and time.%C: Century.%x: Local version of date.%X: Local version of time.%%: A % character.%G: ISO 8601 year.%u: ISO 8601 weekday (1-7).%V: ISO 8601 weeknumber (01-53).
