Exercise 7: Solution & First Solver

NITIN GUPTA

 Healthy Programmer. A program we coders definitely require. The problem statement to the exercise is:

Assume that a programmer works at the office from 9-5 pm. We have to take care of his health and remind him three things,

  • To drink a total of 3.5-liter water after some time interval between 9-5 pm.
  • To do eye exercise after every 30 minutes.
  • To perform physical activity after every 45 minutes.

Instructions:

The task is to create a program that plays mp3 audio until the programmer enters the input which implies that he has done the task.

  • For Water, the user should enter “Drank”
  • For Eye Exercise, the user should enter “EyDone”
  • For Physical Exercise, the user should enter “ExDone”

After the user entered the input, a file should be created for every task separately, which contains the details about the time when the user performed a certain task.

Challenge:

  • You will have to manage the clashes between the reminders. Such that no two reminders play at the same time.
  • Use pygame module to play audio.

from pygame import mixer meaning:

In order to play music/audio files in pygame , pygame.mixer is used (pygame module for loading and playing sounds). This module contains classes for loading Sound objects and controlling playback.

from datetime import datetime python meaning:
In Python, date and time are not a data type of their own, but a module named datetime can be imported to work with the date as well as time. ... datetime – Its a combination of date and time along with the attributes year, month, day, hour, minute, second, microsecond, and tzinfo.

from time import time meaning:

As the name suggests Python time module allows to work with time in Python. It allows functionality like getting the current time, pausing the Program from executing, etc. So before starting with this module we need to import it.

What is mixer init ()?:
pygame.mixer.init. — initialize the mixer module.
mixer module helps control the music used in pygame programs.

Python | Playing audio file in Pygame:
  1. Starting the mixer mixer.init()
  2. Loading the song. mixer.music.load("song.mp3")
  3. Setting the volume. mixer.music.set_volume(0.7)
  4. Start playing the song. mixer.music.play()

if __name__ == “__main__” :

 simple words, by using __name__, we can check whether our module is being imported or run directly.

If we run it in the same module that it is created in, then it will print “main” onto the screen; otherwise, if it is being used elsewhere, then it will print the name of its module or file it is created in.

main is a point of the program from where the program starts its execution. Every program has its own main function. The main function can only be executed when it is being run in the same program. If the file is being imported, then it is no longer the main function because the file that is importing it has its own “main” function.

Code as described/written in the video

        if input_of_user == stopper:
            mixer.music.stop()
            break

def log_now(msg):
    with open("mylogs.txt", "a") as f:
        f.write(f"{msg} {datetime.now()}\n")

    # musiconloop("water.mp3", "stop")
    init_water = time()
    init_eyes = time()
    init_exercise = time()
    watersecs = 40*60
    exsecs = 30*60
    eyessecs = 45*60

    while True:
        if time() - init_water > watersecs:
            print("Water Drinking time. Enter 'drank' to stop the alarm.")
            musiconloop('water.mp3', 'drank')
            init_water = time()
            log_now("Drank Water at")

        if time() - init_eyes >eyessecs:
            print("Eye exercise time. Enter 'doneeyes' to stop the alarm.")
            musiconloop('eyes.mp3', 'doneeyes')
            init_eyes = time()
            log_now("Eyes Relaxed at")

        if time() - init_exercise > exsecs:
            print("Physical Activity Time. Enter 'donephy' to stop the alarm.")
            musiconloop('physical.mp3', 'donephy')
            init_exercise = time()
            log_now("Physical Activity done at")

HOW IMPORT WORKS IN PYTHON?

NITIN GUPTA
  How does the import keyword work? When we write a certain module name along with the  import  keyword, it will start searching for a file with that name having an extension  .py . After finding the file, it will import it into our program, which means that it will permit our program to use the functions of the certain module we imported. We can import a module named  “sys”  to see the path that our import statement takes while searching for a module. import sys print ( sys . path ) Copy sys.path  prints out a list of directories. When we tell Python to import something, then it looks in each of the listed locations in order.  A common mistake that most of the beginners do and also the primary reason for making this tutorial is, why can’t we name our file, the same as the name of a module. The reason is associated with the path. When we give our file a name same as the name of a module, then instead of importing the original module, the system ...

Exercise 5: Health Management System

NITIN GUPTA
  Exercise#5 The task is to create a " Health Management System ." Suppose you are a fitness trainer and nutritionist. You have to deal with three clients, i.e., (Harry, Rohan, Hammad). For each client, you have to design their exercise and diet plan. Instructions: Create a food log file for each client Create an exercise log file for each client. Ask the user whether they want to log or retrieve client data. Write a function that takes the user input of the client's name. After the client's name is entered, it will display a message as "What you want to log- Diet or Exercise". Use function def getdate ( ) : import datetime return datetime . datetime . now ( ) Copy The purpose of this function is to give time with every record of food or exercise added in the file. Write a function to retrieve exercise or food file records for any client. You are advised to participate in solving this problem. This task helps you to become a good pr...

*args and **kwargs In Python

NITIN GUPTA
  Before discussing *args and **kwargs, we should have a basic knowledge about types of arguments. In Python programming, there are two types of arguments that can be passed in a function. positional arguments keyword arguments Positional arguments  are the one in which an order has to be followed while passing arguments. We have been dealing with them until now. We know how normal functions work with positional arguments, so now we will directly start exploring keyword arguments. But to understand them, we have to know about asterisk or more commonly known in Perl 6 and ruby as a splat operator.  Asterisk is used in python as a mathematical symbol for multiplication, but in case of arguments, it refers to unpacking. The unpacking could be for a list, tuple, or a dictionary. We will discover more about it by defining *args and **kwargs. *args: args is a short form used for arguments. It is used to unpack an argument. In the case of *args, the argument could be a list or t...
