The oct () function in Python

The oct () function is one of Python's built-in functions, which is used to convert an integer to the corresponding octal. What syntax is the oct () function, and what parameters, let's find out in this article Quantrimang.

Syntax oct () function in Python

 oct(x)

Parameters of oct () function:

oct () has only one parameter:

x : is integer (object int)

x could be:

An integer (binary, decimal or hexadecimal).

If x not 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?

 # thập phân sang bát phân print('oct(10) co gia tri la:', oct(10)) # nhị phân sang bát phân print('oct(0b101) co gia tri la:', oct(0b101)) # thập lục 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.
