What is python used for
Python is the high-level programming language that is used for websites, developing desktop GUI and web applications. It is one of the famous programming languages. It enables you to concentrate on the beginning functionality of the application by taking care of mutual programming tasks. You can use Python to build a model of the software application quickly. Also, you can create the software application immediately from the prototype barely by refactoring the Python code.
Python even makes it simpler for you to conduct testing and coding simultaneously by approving a test ridden development approach. It is designed with features to promote data examination and visualization. You can take benefit of the data analysis features of Python to build tailored big data solutions without plopping more time and effort.
At the similar time, the data APIs and visualization archives provided by Python enable you to visualize and illustrate data in a further appealing and helpful way. You even have the choice to select from a vast range of open-source Python frames and development tools. At present, Python supports various operating networks. It enables you to operate a similar code on multiple platforms. The easy syntax rules of the programming language distant make it simpler for you to maintain the code source readable and application maintainable. Like as, there have lots of reasons that attract you.
Yet, Python, like other programming languages, has its own deficiencies. It needs some of the permanent features given by another modern programming language. Therefore, you have to use Python modules, frameworks, and libraries to stimulate custom software growth. Also, numerous studies have indicated that Python is quieter than numerous widely used programming languages including C++ and Java.
You have to speed up the Python application by creating changes to the application. But you can ever use Python to speed up software development and streamline software keep.
How to do absolute value in python
The abs() function returns the absolute value of the given number in Python. The abs() function takes an argument which is the number that you want to get the absolute value. The argument value can be:
- An integer number (negative or positive)
- A float number (negative or positive)
- A complex number
Following is the syntax for abs() method −
abs( x )
- x − This is a numeric expression.
This method returns absolute value of x.
The following example shows the usage of abs() method.
#!/usr/bin/python print "abs(-45) : ", abs(-45) print "abs(100.12) : ", abs(100.12) print "abs(119L) : ", abs(119L)
When we run above program, it produces following result −
abs(-45) : 45 abs(100.12) : 100.12 abs(119L) : 119
