0o333

0o333 is an octal number literal. The prefix 0o signals octal notation in several programming languages, most prominently Python 3. The digits 3, 3, 3 form the octal value 333, which converts to decimal 219 and hexadecimal 0xDB. In binary terms, it corresponds to the 9-bit pattern 011011011.

In programming, 0o333 is a valid integer value that evaluates to 219. It can be used in arithmetic, bitwise operations, or as a bitmask like any other integer, depending on the language and context. The 0o prefix helps distinguish octal literals from decimal or hexadecimal forms.

In Unix-like systems, 0o333 can be interpreted as a file permission mode if used in a context that accepts octal notation. The octal digit 3 means the permissions write and execute, but not read, for the corresponding user category. Therefore, 333 as a mode would grant write and execute permissions to the user, group, and others, resulting in a symbolic permission string such as -wx-wx-wx for a regular file, with the initial character dependent on the file type. The mode is typically written as 0333 or 0o333 in contexts that distinguish octal notation.

Compatibility and notes: The 0o prefix is common in Python 3 for octal literals, while other languages may use different syntax—such as a leading 0 in C-family languages or alternative forms in shells. When porting code between languages, verify the correct octal representation and how the language handles octal literals and permissions.
