How To Python! | bandolin

Welcome back, fellow forummers! In this post, we will learn how to build a simple python script, and

what to use behind the scenes.

1. Get a Python IDE 🖥️

To code python, you need an IDE (Integrated Development Environment). We reccommend using

pyCharm by JetBrains, as the community version is free, and includes many nice features.

🎫 Download pyCharm FREE (community) edition at: https://www.jetbrains.com/pycharm/download/

💰 Download pyCharm FULL (original) edition at: https://www.jetbrains.com/pycharm/buy/#personal

Once you have your pyCharm setup, create a new project. Here are some basic commands:

2. Some basic commands ⭐️

Display "HELLO WORLD" on the screen:

print("HELLO WORLD")

Declare and print a variable:

variableName = "HELLO MAN"
print(variableName)

Mathematics with integers:

integer = 1
integer = integer + 4
# Now, the variable "integer" will be equal to 5
integer = integer - 5
# Now, the variable "integer" will be equal to 0
integer = integer +10

integer2 = 5 * 2
integer = integer + integer2
# Now, the variable "integer" will be equal to 20
# and the variable "integer2" will be equal to 10

print("integer =")
print(str(integer))
#     ^^^
# This code turns "integer" from a integer to a string

Collect and print user input:

variableName2 = input("Enter some text: ")
print(variableName2)

Setup custom commands (one time):

command = input("/")
if command == "hello":
    print("command ran successfully")

ADVANCED: Setup custom commands (infinite times):

while True:
    command = input("/")
    if command == "hello":
        print("command ran successfully")

explanation:

while True is called a "while loop". It loops commands under it indefinitely, which in this case helps

us prompt custom commands after they have been used, instead of having to restart the whole script.

4. Libraries 📚

Libraries give you more commands to use in your scripts.

How to import libraries:

# import a library:
import [LIBRARY NAME] as [NICKNAME]
# import a sub-library:
from [LIBRARY NAME] import [SUBLIBRARY NAME]

Popular and Useful libraries:

datetime - used to track date and time

time - used to track time specifically

random - used to create random choices

qrcode - used to encode/decode QR codes

ADVANCED: tkinter - used to create desktop applications

ADVANCED: tkinter messagebox (sub-library) - used to create info, warning, error

and question pop-ups

5. Create a project 🛫

Once you know this, you should be set on creating your first python script. Here are some ideas of what to do:

Reminder software (uses tkinter messagebox and datetime)

World Clock (uses datetime)

Notepad GUI (uses tkinter)

Tic-Tac-Toe

Calculator

Calendar (uses datetime)

Mad Libs

Hangman

there are many more ideas, but these are the easiest to make.
