Python Language Features And Usage
Introduction to Python
Python is a powerful dynamic programming language. It was created by Guido Van Rossum in 1991 at the National Research Institute for Mathematics and Computer Science, Netherlands.
It is Beginner Friendly
Python is a beginner friendly language. It is best known for its simple syntax and readable code. Python is designed to be highly readable.
Python's syntax is very simple and is like English language. Where other programming languages use punctuation marks such as a semicolon (;) etc. Python uses simple English keywords. Apart from English, python is also affected by mathematics.
Both Functional & Object Oriented
Python is also functional and object oriented. You can use it as a scripting language or you can use it as a programming language.
In Python you can either write programs using object oriented features like classes like Java and C #, or you can also create programs by functions just like C and C ++ languages.
Open Source
Python is an open source programming language. Its code is available under the GNU General Public License.
Platform Independent
Python is a platform independent language. It works on different platforms like Windows, Mac, Linux etc.

Features of Python
Python is a unique language. Its features make it different from other languages. Some of the popular features of Python are being described below.
Interpreted
Python is an interpreted language. You do not need to compile your code before running the program. Python code is processed by the interpreter at run time itself.
Python has proved to be an excellent language for rapid prototyping because of this feature of Python. Because you do not need to compile the code again and again.
This can generate rapid prototype of large applications and test them.
However, python is slightly slower than compiled languages like C and C ++ due to being intepreted. Because in those languages the code is run directly once compiled and no processing is done and the python code is processed by the interpreter before it is completely run.
But even then this feature of python is very important because by compiled languages you cannot do important work like rapid prototyping.
Less Code Writing
Performing any task in Python requires writing fewer statements than any other programming language.
Python's syntax is designed to perform tasks in minimal code. In Java, the same code is executed in less than half the code of python.
Dynamically Typed
In Python you do not need to define the data types of variables in advance.Python itself gauges their information types dependent on the qualities stored in the factors.
This reduces the workload of developers. In addition, the developer also avoids potential mistakes related to data types.
Strongly Typed
Python is a strongly typed language. In this, like other programming languages, you cannot convert the value of one data type to the value of another data type.
If you have used C or C ++ languages then you must have found that those languages automatically convert the data of one data type to the value of another data type. But this is not possible in Python.
Usage of Python
As I mentioned earlier python can also be used as a scripting language and can also be used as a programming language. This makes the scope of this language more than other languages.
Some popular and important uses of python are being told next.
- Python is used for server side web development.
- Python is used to handle (analyze) big data.
- Python is used for rapid prototyping.
- Python is used to solve complex mathematical problems.
- Many big organizations like Google, Facebook and Quora etc. use python.
