Python oct()

Python oct() function is used to convert an integer into octal string prefixed with “0o”.

Python oct()

Python oct() function syntax is:

oct(x)

The output of oct() function is a string. We can pass an object as an argument too, in that case, the object must have __index__() function implementation that returns integer.

Let’s look at some simple examples of oct() function.

print(oct(10))

print(oct(0xF))

print(oct(0b1111))

print(type(oct(10)))

Output:

0o12
0o17
0o17
<class 'str'>

Python oct() with object

Let’s look at another example where we will use oct() function with a custom object as an argument. We will implement __index__() function in this object.

class Data:
    id = 0

    def __init__(self, i):
        self.id = i

    def __index__(self):
        return self.id


d = Data(20)

print(oct(d))

Output: 0o24
