OS LIBRARY , TIME LIBRARY

 What is the os library?

It allows us to "talk" to the console. One of the most powerful things we can do with this library is allow it to clear the console


EXAMPLE:

import os

print("Welcome")

print("to")

print("Replit")


os.system("clear")


username = input("Username: ") 

Time Library


We can import a second library by placing a , after the name of the first library.

EXAMPLE:
import os, time
print("Welcome")
print("to")
print("Replit")
time.sleep(10)
os.system("clear")

username = input("Username: ") 


NOTE: 

from replit import audio
import os, time

def play():
  source = audio.play_file('audio.wav')
  source.paused = False # unpause the playback
  while True:
    stop_playback = int(input("Press 2 anytime to stop playback and go back to the menu : ")) # giving the user the option to stop playback
    if stop_playback == 2:
      source.paused = True # let's pause the file 
      return # let's go back from this play() subroutine
    else: 
      continue
  
while True:
  os.system("clear")
  print("🎵 MyPOD Music Player ")
  time.sleep(1)
  print("Press 1 to Play")
  time.sleep(1)
  print("Press 2 to Exit")
  time.sleep(1)
  print("Press anything else to see the menu again")
  userInput = int(input())
  if userInput == 1:
    print("Playing some proper tunes!")
    play()
  elif userInput == 2:
    exit()
  else :
    continue

Hide & Remove,Come Back!,

 Hide & Remove DISCLAIMER: I promise the good stuff is coming back. We have to go through the valley to get to the mountain, right? Sometimes, we want to remove a button, image or piece of text from the screen. To do this, we use pack_forget(). 👉 We'll start with our default tkinter program. import tkinter as tk window = tk.Tk() window.title("Hello World")  window.geometry("300x200")  hello = tk.Label(text = "Hello World")  hello.pack()  button = tk.Button(text = "Click me!")  button.pack() tk.mainloop() 👉 Now I'm going to add a new subroutine to hide the label and call it on a button click. import tkinter as tk window = tk.Tk() window.title("Hello World")  window.geometry("300x200")  # New subroutine def hideLabel():   hello.pack_forget() # Removes the 'hello' label hello = tk.Label(text = "Hello World")  hello.pack()  button = tk.Button(text = "Click me!", command = hideLabel) # Call...

Web Scraping

 Web Scraping Some websites don't have lovely APIs for us to interface with. If we want data from these pages, we have to use a tecnique called scraping. This means downloading the whole webpage and poking at it until we can find the information we want. You're going to use scraping to get the top ten restaurants near you. Get started 👉 Go to a website like Yelp and search for the top 10 reastaurants in your location. Copy the URL.   url = "https://www.yelp.co.uk/search?find_desc=Restaurants&find_loc=San+Francisco%2C+CA%2C+United+States"   Import libraries 👉 Import your libraries. Beautiful soup is a specialist library for extracting the contents of HTML and helping us parse them. Run the Repl once your imports are sorted because we want the Beautiful Soup library to be installed (it'll run quicker this way). import requests from bs4 import BeautifulSoup url = "https://www.yelp.co.uk/search?find_desc=Restaurants&find_loc=San+Francisco%2C+CA%2C+Unite...

String Manipulation

   String Manipulation Does this code look familiar from the insult generator project? name = input("What's your name? ") if name == "David" or name == "david":   print("Hello Baldy!") else:    print("What a beautiful head of hair!") Right now, if the user writes "DAVID" or "david", the if statement works correctly. However, "DaVID" does not give the correct output. To the computer, " david", "dAviD", and "david" are completely different. To simplify what the user typed in, we can add these functions to the end of the name of the variable: .lower() = all letters are lower case .upper() = all letters are upper case .title() = capital letter for the first letter of every word .capitalize() = capital letter for the first letter of only the first word
