Funny, eh? Funny, how?

Dad Jokes

The API we're using today is the awesome icanhazdadjoke. Go and check out their API documentation before continuing. Look at the endpoint to see the URL to access and the format of the data we'll get back.

👉 Here's the code to get a random dad joke and output it. NOTE - The second argument (headers=) in requests.get() is really important. It tells the code that we don't want the website back, we want JSON data in a specific format. Sometimes you need to do that.

import requests, json

result = requests.get("https://icanhazdadjoke.com/", headers={"Accept":"application/json"}) # get a random dad joke from the site endpoint and assign to a variable. The second argument (the header request) tells the script to return the json data as a string.

joke = result.json()

print(json.dumps(joke, indent=2))

👉 I can change the print statement to just output the joke instead of the whole dictionary.

print(joke["joke"])

The API for this site is a really good one to learn from as it gives lots of great examples of how to import jokes in different formats.

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
