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.
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.
