Python Basics: Input, Output, and Variables

This page introduces fundamental concepts in Python programming, focusing on input/output operations and variable types. These are crucial elements for Apprendre Python de A à Z.

The page begins by explaining how to display output in Python using the print() function. This is a core concept in Cours Python for beginners.

Example: To display a simple greeting, use print("Bonjour").

For more complex output, the guide demonstrates how to combine text and variables in print statements.

Example: To print a result with text, use print("Le resultat est", 7, "pommes").

The input() function is introduced as a way to receive user input, which is essential for interactive programs.

Highlight: The input() function allows programs to accept user input, making them more interactive and dynamic.

The guide also covers different variable types in Python:

• Integer numbers (int)
• Floating-point numbers (float)

Definition: Integers are whole numbers, while floating-point numbers can represent fractions or decimal points.

An example is provided to demonstrate how to convert user input to a float:

Example: longueur = float(input("Entrer la longueur")) converts the user's input to a floating-point number and assigns it to the variable longueur.
