Python Web Development is as fun as it is useful for managing complex projects. If you look closely at some of the popular website today, you’ll find that they have been powered by Python. It supports popular frameworks like Django and Flask to build server-side web applications and perfect frontend integration. It cannot be used directly in browser but provides exceptional support to developer who can use JavaScript in frontend and Python for operating on server-side. While working, developers usually engage in various activities that bring out the incredible sense of humor hidden in the Python’s core.
It is one of the features that makes the language much easier to learn as compared to others. Whenever learners start to lose motivation or get bored, they indulge themselves in playing around with code and see it do some extraordinary things.
Plan a Delivery Route
First there is a test to prepare the newbie developers for facing challenges confidently in Python Web Development projects. It is exciting but a difficult puzzle that developers can solve using Python. It is a graph implementation exercise where the developer has to plan a route for a delivery truck to its destination. The delivery area is represented by a 2-D grid of integers where ‘1’ is accessible area, ‘0’ is non-accessible, and ‘2’ is the final destination.
The challenge is to write an algorithm that determines the truck’s distance required to deliver the order. The catch is that the truck can’t leave the grid and must be able to reach the final destination via accessible areas only. Also, the truck can only move (left, right, up, and down) one cell at a time at a time.
It helps in choosing to use the correct data structure which can make a seemingly complex problem into something much simpler. To start the exercise, enter following function and make implementations accordingly to find the optimal route:
#Filename: delivery_route.py
def find_route(area):
return 0
Guess the Number
When learning Python Web Development, most users come across the “Guess the Number” game. It is useful game for programming because it uses random inputs, numbers, and loops from the user. It shows how different values can be converted in to data types and why a developer may need to do this regularly in software development.
In this game the user has to guess the random number between 1 and 100, which the computer has chosen for itself. Each time the user enters a guess, the computer responds whether it’s correct, too high, or too low. Once you have managed to guess, the computer will tell how many turns it took you to guess the correct answer.
To implement the game, you have to write a C++ program, enter source code, and save it save it as ‘guess.py’. Here is the source code:
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
int main()
{
int num, guess, tries = 0;
srand(time(0)); //seed random number generator
num = rand() % 100 + 1; // random number between 1 and 100
cout << “Guess My Number Game\n\n”;
do
{
cout << “Enter a guess between 1 and 100 : “;
cin >> guess;
tries++;
if (guess > num)
cout << “Too high!\n\n”;
else if (guess < num)
cout << “Too low!\n\n”;
else
cout << “\nCorrect! You got it in ” << tries << ” guesses!\n”;
} while (guess != num);
return 0;
}
See the In-Jokes Included in Python
One of the reasons why developers love Python Web Development is that it has a friendly terminology that often includes some witty quips. Python developers have embedded in the framework, their own feelings about certain issues of programming. These are also called easter eggs that occur when entering certain functions.
For example, entering __hello__ displays the phrase “Hello World”. It is actually a frozen module meant as a test case for frozen module support and its source code is automatically generated by the freeze utility.
A famous easter egg import this displays a poem ‘Zen of Python’ by Guido van Rossum, the chief developer of Python. The poem included in the program is meant to hash out guidelines related to the development of Python code. Following these guidelines can improve readability, usability and maintainability of the code.
from __future__ import braces is another code that will not do anything but return an interesting response from Python. When users try to execute this code, the system answers ‘SyntaxError: not a chance’ making it clear that you cannot enable ‘create blocks with braces’ feature so indentation is the only way.
One is import antigravity that surprisingly takes the user to a funny comic book website dedicated to Python. In the comics you can see one cartoon asks another “how are you flying” and the other one answers “I just typed import antigravity”. This code will certainly doesn’t make you fly but serves it purpose as a joke.
Print emojis
Everyone today loves to communicate in emojis so why not your programming terminal? It is quite fun to write codes that gives output in emojis and it is really simple as well. Unlike the lengthy and complicated algorithm in most programs, printing emojis can be quick if you understand emojis. They are stored in the memory in binary format but it can be difficult to identify emojis that way. In Python Web Development this process becomes easy by using any of the 3 methods: Unicodes, CLDR Names, emoji module.
Every emoji has predefined Unicode characters but you just need to replace ‘+’ with “ooo” and add prefix. For example, U+1f500 would be entered as Print(“\U0001f600”) and the output will be a ‘grinning face emoji’.
Emojis also have CLDR (Common Locale Data Repository) short names that are simpler than using Unicodes. You simply have to type the CLDR name of the emoji you want and it will appear. For example, Print(“\N{grinning face}”) will also display the ‘grinning face emoji’.
Python also provides emoji module that can be installed by running pip install emoji in the terminal.
