Python Data Types
Built-in Data Types In programming, data type is an important concept. Variables can store data of different types, and different types can do different things. Python has the following data types built-in by default, in these categories: Text Type: str…
Python – Global Variables
Global Variables Variables that are created outside of a function (as in all of the examples in the previous pages) are known as global variables. Global variables can be used by everyone, both inside of functions and outside. Example Create…
Python – Output Variables
Output Variables The Python print() function is often used to output variables. Example x = “Python is awesome” print(x) In the print() function, you output multiple variables, separated by a comma: Example x = “Python” y = “is” z =…
Python Variables – Assign Multiple Values
Many Values to Multiple Variables Python allows you to assign values to multiple variables in one line: Example x, y, z = “Orange”, “Banana”, “Cherry” print(x) print(y) print(z) Note: Make sure the number of variables matches the number of values,…
Python – Variable Names
Variable Names A variable can have a short name (like x and y) or a more descriptive name (age, carname, total_volume). Rules for Python variables: A variable name must start with a letter or the underscore character A variable name…
Python Variables
Variables Variables are containers for storing data values. Creating Variables Python has no command for declaring a variable. A variable is created the moment you first assign a value to it. Example x = 5 y = “John” print(x) print(y)…
Python Comments
Comments can be used to explain Python code. Comments can be used to make the code more readable. Comments can be used to prevent execution when testing code. Creating a Comment Comments starts with a #, and Python will ignore…
Python Syntax
Execute Python Syntax As we learned in the previous page, Python syntax can be executed by writing directly in the Command Line: >>> print(“Hello, World!”) Hello, World! Or by creating a python file on the server, using the .py file…
