The Oct ()() Function in Python

This updated guide examines The Oct ()() Function in Python and organizes the essential facts, background, and practical takeaways in clear American English.

Syntax oct () function in Python

oct(x)

Parameters of oct () function:

oct () has only one parameter:

• x: is integer (object int)

xcould be:

• An integer (binary, decimal or hexadecimal).
• Ifxnot an integer, it is necessary to use __index __ () to return an integer

Return value from oct ()

The oct () function converts an integer to the corresponding octal number.

Example 1: How does the oct () function work?

# th?p phân sang bát phân print('oct(10) co gia tri la:', oct(10)) # nh? phân sang bát phân print('oct(0b101) co gia tri la:', oct(0b101)) # th?p l?c phân sang bát phân print('oct(0XA) co gia tri la:', oct(0XA))

Running the program, the result is returned:

oct(10) co gia tri la: 0o12 oct(0b101) co gia tri la: 0o5 oct(0XA) co gia tri la: 0o12

Example 2: oct () with custom objects

ass Person: age = 23 def __index__(self): return self.age def __int__(self): return self.age person = Person() print('The oct is:', oct(person))

Running the program, the result is returned:

The oct is: 0o27

Here, the Person class implements __index __ () and __int __ (). That is why we can use oct () on Person objects.

Note: For compatibility, you should implement __int __ () and __index __ () with the same output.
