PYTHON - Coggle Diagram
PYTHON
Python is a programming language used for many tasks, including developing software and websites, data analysis, and machine learning. It's also used for automating tasks, scientific computing, and more.

Data analysis: Python is used to analyze data sets, identify issues, and automate solutions.
Task automation: Python can be used to automate tasks, such as renaming files, updating shopping lists, and sending reminders.
Productivity tools: Python can be used to build productivity tools, such as games and desktop apps.

A Python library is a collection of pre-written code, functions, classes, and routines that developers can use to perform tasks. Libraries can help developers automate tasks, analyze data, and perform mathematical computations.
Pandas
An open-source library for data manipulation and analysis. It's often used in data science for cleaning, exploring, and analyzing data.
Matplotlib
An open-source library for data visualization. It's used to create static, animated, and interactive visualizations.
NumPy
An open-source library for scientific and mathematical computing. It's used for numerical computations on large arrays and multi-dimensional matrices.
The data types in Python that we will look at in this tutorial are integers, floats, Boolean, and strings. If you are not comfortable with using variables in Python, our article on how to declare python variables can change that.
Python has several data types, including numeric, string, list, tuple, and dictionary.
Float
Stores real numbers with decimal values, positive or negative. For example, 3.14, -2.71
Integer
Stores whole numbers, positive or negative, with no limit on length. For example, 1, -99, 10, 25
String data types
Stores a sequence of Unicode characters, such as letters, numbers, and special symbols. Characters can be enclosed in single, double, or triple quotes.
Complex
Stores complex numbers with real and imaginary parts. For example, 2+4i, 6-8i
Tuple data types
Stores a sequence of characters separated by commas and enclosed in round brackets. Tuples are immutable, meaning they cannot be changed after creation.
List data types
Stores a collection of items of different types, separated by commas and enclosed in square brackets. Lists are mutable, meaning they can be changed after creation.
Dictionary data types
Stores data values in the form of key-value pairs, enclosed in curly brackets. Dictionaries are mutable, meaning they can be changed after creation.
Boolean data types
Stores values that are either true or false. Boolean values are important for if statements and other conditional expressions.
Pythonic describes code that doesn't just get the syntax right but uses the language in the way it's intended to be used. Here's how to optimize your Python code. Written by Xiaoxu Gao. Published on Dec. 06, 2023.
Python code is a set of instructions written in the Python programming language. Python is a high-level, object-oriented language that's used for many different tasks, including building software, analyzing data, and creating games.
