For converting one integer to binary, we can write our own function that can take one integer value and return its binary equivalent. Or, we can use bin library function that does the same thing and we don’t need any other library for that.
In this post, I will show you how bin works with one example.
The syntax of bin() is as below:
Here, we are passing one number no to this function. This number no is the number for which we are finding the binary value. It returns the binary representation in string format.
Below is an example that uses bin to find the binary of different numbers :
print("Binary representation of 45 is ",bin(45)) print("Binary representation of 40 is ",bin(40)) print("Binary representation of 32 is ",bin(32)) print("Binary representation of 10 is ",bin(10)) print("Binary representation of 0 is ",bin(0)) print("Binary representation of 100 is ",bin(100))
It will print :
Binary representation of 45 is 0b101101 Binary representation of 40 is 0b101000 Binary representation of 32 is 0b100000 Binary representation of 10 is 0b1010 Binary representation of 0 is 0b0 Binary representation of 100 is 0b1100100
We can also use bin() with a custom class. For that, we need to implement index() method in that class that will return one integer value.
class Student: def __init__(self, age, marks): self.age = age self.marks = marks def __index__(self): return self.age + self.marks student = Student(5, 5) print("Binary representation of Student(5,5) : ", bin(student))
It will print:
Binary representation of Student(5,5) : 0b1010
Here, index is returning the sum of age and marks in the Student class. For the Student object we created, it will return 10. So, when we are calling bin on the Student object, i.e. on student, it calculates the binary of 10 which is 0b1010.
This example shows you how to use bin to quickly find out the binary representation of a number in python. You can write your own function to do that or use bin for a quick alternative.
