WHAT IS PYTHON ?
Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Its high-level built in data structures, combined with dynamic typing and dynamic binding, make it very attractive for Rapid Application Development, as well as for use as a scripting or glue language to connect existing components together. Python’s simple, easy to learn syntax emphasizes readability and therefore reduces the cost of program maintenance. Python supports modules and packages, which encourages program modularity and code reuse.
WHAT ARE PYTHON MODULES ?
In simple terms, we can consider a module to be the same as a code library or a file that contains a set of functions that you want to include in your application.
With the help of modules, we can organize related functions, classes, or any code block in the same file. So, It is considered a best practice while writing bigger codes for production-level projects in Data Science is to split the large Python code blocks into modules containing up to 300–400 lines of code.
The module contains the following components:
Definitions and implementation of classes,
Functions that can be used inside another program.
What is Python and why it is used?
Python is a computer programming language often used to build websites and software, automate tasks, and conduct data analysis. Python is a general-purpose language, meaning it can be used to create a variety of different programs and isn’t specialized for any specific problems USER DEFINED MODULES ?
Create a Module
To create a module, create a Python file with a .py extension.
Call a Module
Modules created with a extension can be used in another Python source file, using the import statement.
WHAT IS PYTHON ? AND WHY IT IS UDED ?
WHAT IS PYTHON USED FOR?
Python is commonly used for developing websites and software, task automation, data analysis, and data visualization. Since it’s relatively easy to learn, Python has been adopted by many non-programmers such as accountants and scientists, for a variety of everyday tasks, like organizing finances.
“Writing programs is a very creative and rewarding activity,” says University of Michigan and Coursera instructor Charles R Severance in his book Python for Everybody. “You can write programs for many reasons, ranging from making your living to solving a difficult data analysis problem to having fun to helping someone else solve a problem.”
What can you do with python? Some things include:
Data analysis and machine learning
Automation or scripting
Software testing and prototyping
Python is often used to develop the back end of a website or application—the parts that a user doesn’t see. Python’s role in web development can include sending data to and from servers, processing data and communicating with databases, URL routing, and ensuring security. Python offers several frameworks for web development. Commonly used ones include Django and Flask.
Some web development jobs that use Python include back end engineers, full stack engineers, Python developers, software engineers, and DevOps engineers.
WHY IS PYTHON IS SO POPULAR ?
Python is popular for a number of reasons. Here’s a deeper look at what makes it so versatile and easy to use for coders.
It has a simple syntax that mimics natural language, so it’s easier to read and understand. This makes it quicker to build projects, and faster to improve on them.
It’s versatile. Python can be used for many different tasks, from web development to machine learning.
It’s beginner friendly, making it popular for entry-level coders.
It’s open source, which means it’s free to use and distribute, even for commercial purposes.
Python’s archive of modules and libraries—bundles of code that third-party users have created to expand Python’s capabilities—is vast and growing.
Python has a large and active community that contributes to Python’s pool of modules and libraries, and acts as a helpful resource for other programmers. The vast support community means that if coders run into a stumbling block, finding a solution is relatively easy; somebody is bound to have run into the same problem before.
WHAT TYPES OF JOB USE PYTON?
Since python is a general-purpose language, it’s used across a variety of fields and industries. These are just a few job titles that may use Python:
- Data analyst
- Data scientist
- Ethical hacker/penetration tester
- Software engineer
- Data journalist
- Cloud architect
- QA enginees
PYTHON QUICKSTART ?
Python is an interpreted programming language, this means that as a developer you write Python (.py) files in a text editor and then put those files into the python interpreter to be executed.
TOP 7 DATA OF PYTHON
Python Numbers. We can find complex numbers, floating point numbers and integers in the category of Python Numbers.
Python List. An ordered sequence of items is called List.
WHAT CAN PYTHON DO?
- Python can be used on a server to create web applications.
- Python can be used alongside software to create workflows.
- Python can connect to database systems. It can also read and modify files.
- Python can be used to handle big data and perform complex mathematics.
- Python can be used for rapid prototyping, or for production-ready software development.
WHY PYTHON ?
Python works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc).
Python has a simple syntax similar to the English language.
Python has syntax that allows developers to write programs with fewer lines than some other programming languages.
Python runs on an interpreter system, meaning that code can be executed as soon as it is written. This means that prototyping can be very quick.
Python can be treated in a procedural way, an object-oriented way or a functional way.
