Tutorials - Trey Hunner: Intro to Python for Brand New Programmers

Basic Syntax

• Python has a syntax similar to math, but with a different operator system
• Operators can be used to add, multiply, and divide numbers

Variables and Types

• Variables are used to store values and are case-sensitive
• Numbers can be integers or floats
• Strings are sequences of characters, which can be concatenated together
• Lists are mutable sequences that can be used to store multiple values

Control Structures

• Conditional statements (“if” and “elif”) are used to make decisions in code
• Loops (“for” and “while”) are used to repeat actions
• An “else” clause can be used with “if” and “elif” statements

Functions

• Functions are reusable blocks of code that can be called multiple times
• Functions can take arguments and return values *_functions.py is used to define and call functions

Modules and Imports

• Modules are reusable code libraries that can be imported into other code
• The “import” statement is used to bring a module into the current code
• The “import math” statement is used to bring the math module into the current code

Exception Handling

• Errors can occur in code when syntax or runtime errors occur
• Exception handling is used to catch and handle errors in code
• The “try” and “except” keywords are used to define error handling code

More

• The len() function is used to get the length of a sequence (such as a list or string)
• The type() function is used to get the type of an object
• The “print()” function is used to output text or values to the console
• The “input()” function is used to get input from the user and store it in a variable
