Python Lesson!

stoporinjail

Hello everyone! I have decided to make lessons for Python, right here! This might be converted into an interactive repl, depending on how it goes. This is meant for completely new people to Python.

What we will be learning

Lesson 1

  • Printing
  • Variables
  • F strings

Lesson 2

  • Multiple value variables
  • Imports: Random, time
  • Dictionaries
  • Loops
  • If, elif, else statements
  • User inputs
    I plan to have 6 topics for each lesson excluding this one.

Lesson 1:

This post will be lesson 1. I will post another in a few days for lesson 2.

Printing

In Python, the most important thing you will have to know is printing! It prints (writes) out a value.

How to:

print("value")

Example:

print("Hello world")

If you run the program, the console (black screen on the right) will say Hello world

Variables

Variables are like a box in Python. You can put things in the box, remove things in the box, and even find out what's in the box.

How to:

variable_name = "Value"

or for numbers:

variable_name = number

The number does not go into quotes.
To print out a variable:

print(variable_name)

or

print(variable_name, "Hi")

Examples:

name = "Bob" print("Hi", name)

Output: Hi, Bob

F Strings

You can use an F string to print out variables and values more efficiently.

How to:

variable_name = "value" print(f'your text here {variable_name}')

You must use the f before the quotes.

Example:

name = 'Bob' print(f"Hello, {name}")

Output: Hello, Bob

Conclusion

So that was lesson 1! Have a great day! Lesson 2 will be released soon.

Other Lessons:

Other lesson links will be posted here.

bruh in C and C++ you can do more things. It is like Java, you can create games with them. Python is a growing language, and is easier to write, but you can do less complex things with it. With libraries though, you can match the things C++ and C does, but it will be slower in execution. No-one would create an OS in Python because C and C++ would be way faster, and right when you press a button, you will get instant feedback.
