oct(x)
where
| Parameter | Required/Optional | Description |

In this example, we take an integer in x, and convert it into octal string using oct() function.
Python Program
x = 144 result = oct(x) print(result)Try Online
Output
0o220
2. Octal String for Class Object
In this example, we define a class A, with __index__() method that returns hash of this class instance (an integer). and convert it into octal string using oct() function.
Python Program
class A:
def __index__(self):
return hash(self)
result = oct(A())
print(result) Try Online Output
0o2001345361
Conclusion
