# Python3.x Python oct() Function
[ Python3 Built-in Functions](#)
* * *
`oct()` is a built-in function in Python used to convert an integer to an octal string.
Octal is a base-8 numeral system commonly used in computing, where digits 0-7 represent values. The `oct()` function returns an octal string prefixed with "0o".
**Word Origin**: `oct` is an abbreviation for "octal".

## Basic Syntax and Parameters
### Syntax Format
oct(x)
### Parameter Description
* **Parameter x**:
* Type: Integer
* Description: The integer to be converted to octal.
### Function Description
* **Return Value**: Returns an octal string prefixed with "0o".
* * *
## Examples
### Example 1: Basic Usage
## Example
# Basic conversion
print(oct(8))# Output: 0o10
print(oct(9))# Output: 0o11
print(oct(64))# Output: 0o100
print(oct(255))# Output: 0o377
# Negative numbers
print(oct(-8))# Output: -0o10
# Zero
print(oct(0))# Output: 0o0
# 1-7
for i in range(1,8):
print(f"{i} -> {oct(i)}")
# Output: 1 -> 0o1, 2 -> 0o2, ..., 7 -> 0o7
**Expected Output:**
0o100o110o1000o377-0o100o01 -> 0o12 -> 0o23 -> 0o34 -> 0o45 -> 0o56 -> 0o67 -> 0o7
**Code Analysis:**
1. The returned string starts with "0o" (lowercase letter o), indicating octal.
2. Each octal digit can represent one of eight values (0-7).
### Example 2: Comparison with Hexadecimal and Binary
## Example
n =64
# Different base representations
print(f"Decimal: {n}")
print(f"Binary: {bin(n)}")
print(f"Octal: {oct(n)}")
print(f"Hexadecimal: {hex(n)}")
# Removing the prefix
print(f"Octal (no prefix): {oct(n)[2:]}")
print(f"Hexadecimal (no prefix): {hex(n)[2:]}")
**Expected Output:**
Decimal: 64Binary: 0b1000000Octal: 0o100Hexadecimal: 0x40
Python provides the `bin()`, `oct()`, and `hex()` functions for converting between different bases.
