Python Automation

Concepts

Syntax: Syntax refers to the set of rules that define how Python code is structured. It dictates how you write statements, expressions, and instructions for the computer to understand. Proper indentation (using spaces) is essential in Python, unlike some other programming languages.
Strings: Strings are sequences of characters enclosed in single (') or double (") quotes. They represent text data that your program can use. Examples:
Numericals: Numericals represent numeric data in Python. There are two main kinds: Integers (whole numbers): Represented by whole numbers without decimals. Example: age = 30 Floats (decimal numbers): Numbers with a decimal point. Example: pi = 3.14159
Variables: Variables are named containers that store data in your program. You can think of them as boxes with labels where you can place and retrieve information. Naming: Choose descriptive names that reflect the data they hold (e.g., message, temperature). Assigning values: The equal sign (=) is used to assign a value to a variable. Example: temperature = 25. Reassignment: Variables are flexible; you can change the value stored in them later in your code.
Constants: Constants represent fixed values that shouldn't change during your program's execution. Unlike variables, they are usually written in ALL_CAPS with underscores for clarity. They help improve code readability and maintainability. Example: MAX_SPEED = 100 (speed limit).

Lists: Ordered collections of items enclosed in square brackets []. They can hold elements of different data types. Useful for storing sequences of data. Example: fruits = ["apple", "banana", "cherry"]
Tuples: Similar to lists but immutable (cannot be changed after creation). Useful for representing data that shouldn't be modified. Example: coordinates = (10, 20)
Dictionaries: Unordered collections of key-value pairs enclosed in curly braces {}. Used to store data associated with unique keys. Example: person = {"name": "Bob", "age": 35}
