Python Terms
When we begin to learn Python it is useful to learn a few terminologies that are usually used with Pythons. The definitions of these terms are given here.
Python is a versatile and widely-used programming language. Here are some important terms and their definitions to help you get started:
Python: Python is a high-level, interpreted programming language known for its simplicity and readability. It emphasizes code readability and has a large standard library.
Variable: A variable is a named location in memory that stores a value. It allows you to store and manipulate data in your program.
Data Type: Every value in Python has a specific data type, which defines the kind of data the value represents. Common data types include integers (int), floating-point numbers (float), strings (str), and booleans (bool).
String: A string is a sequence of characters enclosed in single quotes ('like this') or double quotes ("like this"). It represents textual data and can be manipulated using various string operations.
List: A list is an ordered collection of items, enclosed in square brackets ([]). It can contain elements of different data types and supports various operations such as indexing, slicing, appending, and removing elements.
Tuple: A tuple is an ordered and immutable collection of items, enclosed in parentheses (()). Once defined, its elements cannot be changed. Tuples are commonly used to represent fixed collections of related values.
Dictionary: A dictionary is an unordered collection of key-value pairs, enclosed in curly braces ({}). Each key is unique and associated with a value. It allows fast retrieval of values based on their keys.
Conditional Statement: A conditional statement allows the execution of different code blocks based on specified conditions. The if statement is commonly used for this purpose, and it can be extended with else and elif (short for "else if") clauses.
Loop: A loop is used to repeatedly execute a block of code until a certain condition is met. The for loop is used to iterate over a sequence (e.g., a list), and the while loop repeats as long as a condition remains true.
Function: A function is a reusable block of code that performs a specific task. It takes input arguments, performs operations, and returns a result. Functions help in organizing code and making it more modular.
Module: A module is a file containing Python code that defines functions, classes, and variables. It allows you to logically organize your code and reuse it in other programs using the import statement.
Exception: An exception is an error that occurs during program execution. Python provides mechanisms for handling and raising exceptions, allowing you to gracefully deal with unexpected situations.
These are just a few of the essential terms in Python. As you progress in your learning, you'll encounter more concepts and keywords. Good luck with your Python journey!
