Python’s Built-in Types and Sequences

You know, the stuff that makes this language so ***** popular among programmers everywhere. But before we dive into all of that fancy jargon, let me first explain what these terms actually mean in plain English.

First off, a type is just like it sounds: it’s a category or classification for different kinds of data.In Python, there are several built-in types that you can use to store and manipulate information. These include integers (whole numbers), floats (decimal numbers), strings (text), lists (ordered collections of items), tuples (similar to lists but immutable), dictionaries (unordered collections of key-value pairs), and sets (collections of unique values).

Now, sequences. These are essentially just ordered collections of data that can be accessed using indexing or slicing.In Python, there are three built-in sequence types: strings, lists, and tuples. Strings are used for storing text (like “hello world”), while lists and tuples are both used for storing multiple items in a single variable (but with some key differences).

So why is all of this so important? Well, understanding Python’s built-in types and sequences can help you write more efficient and readable code. For example, if you need to store a list of numbers, it might be better to use a list instead of creating multiple variables for each individual number (which would take up more memory and make your code harder to manage).

Here’s an example script that demonstrates how to create and manipulate some basic data types in Python:

# Define a list of numbers
numbers = [1, 2, 3]

# Define some variables using different built-in types
my_int = 42 # integer (whole number)
my_float = 3.14 # float (decimal number)
my_string = "hello world" # string (text)
my_list = numbers # list (ordered collection of items)
my_tuple = ("apple", "banana") # tuple (similar to a list but immutable)
my_dict = {"name": "John Doe"} # dictionary (unordered collection of key-value pairs)
my_set = {1, 2, 3} # set (collection of unique values)

# Print out the contents of each variable using string concatenation and f-strings
print(f"My integer is: {my_int}") # prints the value of my_int variable
print(f"My float is: {my_float}") # prints the value of my_float variable
print(f"My string is: {my_string}") # prints the value of my_string variable
print(f"My list is: {my_list}") # prints the value of my_list variable
print(f"My tuple is: {my_tuple}") # prints the value of my_tuple variable
print(f"My dictionary is: {my_dict}") # prints the value of my_dict variable
print(f"My set is: {my_set}") # prints the value of my_set variable

As you can see, this script defines several variables using different built-in types and then prints out their contents using string concatenation and f-strings. This allows us to easily view the data in a human-readable format without having to manually type it all out by hand.
