If you’re new to programming or just want a refresher course, this is the perfect place for you.
Before anything else: what are data structures? Well, they’re basically containers that hold your data in an organized way.In Python, we have several options to choose from let’s take a look!
1) Strings (): These are the most basic of all data structures. They consist of characters enclosed by quotes or single/double quotation marks. For example: “hello world” and ‘this is a string too’. You can use them to store text, numbers, or even emojis!
2) Lists (): These are like arrays in other programming languages. They allow you to store multiple values of any data type strings, integers, floats, etc. For example: [1, 2, “three”, 4.5] is a list with four elements.
3) Tuples (): These are similar to lists but they’re immutable, meaning you can’t change their values once they’ve been created. They’re useful for storing fixed sets of data that won’t be modified later on in your program. For example: (“apple”, “banana”) is a tuple with two elements.
4) Dictionaries (): These are like hash maps or associative arrays in other programming languages. They allow you to store key-value pairs, where the keys can be any immutable data type and the values can be anything at all! For example: {“name”: “John”, “age”: 30} is a dictionary with two key-value pairs.
5) Sets (): These are like unordered collections of unique elements. They’re useful for storing large amounts of data that don’t need to be sorted or indexed in any particular way. For example: {1, 2, “three”, 4} is a set with four elements.
Python’s built-in data structures the basics for beginners. Remember, practice makes perfect (or at least better) so go ahead and try them out in your own programs.
