Python bin() Method - Python Library Function

Posted in Programming   LAST UPDATED: AUGUST 2, 2019

    In this tutorial, we will learn to implement python bin() library method. The main use of bin() function is, it converts and returns the binary equivalent string of a given integer.

    What if, the parameter of bin method is not an integer?

    In this case, bin() method implements __index__() method to return an integer.

    python bin method

    The bin method take only one parameter. Below is the syntax for bin() method.

    Syntax:

    bin( X )
    
    # X can be an integer, or object, or anything the returns integer.




    1. Executing the bin() Method

    If you pass a string, or anything that doesn't an integer, as a parameter you will get TypeError exception saying the type cannot be interpreted as an integer.

    Be aware of that, while using bin() method.

    number = 10
    print('The binary equivalent of 5 is:', bin(number))
    

    After executing the program, the output will be:

    The binary equivalent of 5 is: 0b1010




    2. How to use __index__() method with Objects

    __index__() is used to convert an object into a binary equivalent string.

    class StudyToNight:
        study = 10
        to = 20
        night = 40
        
        def __index__(self):
            return self.study+ self.to+ self.night
            
    print('The binary equivalent of quantity is:', bin(StudyToNight()))
    

    After Executing the program, the output will be:

    The binary equivalent of quantity is: 0b1000110



    Conclusion:

    Pheww! This is it. I hope that you enjoyed the post and learned about the bin() python library function. If you feel that this post is useful, please share it with your friends and colleagues.

    Thanks for reading it till the end.
