Python, a versatile programming language, offers a plethora of built-in functions that facilitate various operations. Among these functions is `oct()`

, a powerful tool for converting integers to octal strings.

**Understanding oct() Function**

The `oct()`

function in Python is primarily used for converting integers to octal notation. Its syntax is straightforward:

```
oct(x)
```

Here, `x`

represents the integer that you want to convert to its octal equivalent.

**Example 1: Basic Usage**

```
num = 10
octal_num = oct(num)
print("Octal representation of", num, "is:", octal_num)
```

**Output 1:**

```
Octal representation of 10 is: 0o12
```

**Example 2: Using in a Loop**

```
for i in range(5):
print("Octal representation of", i, "is:", oct(i))
```

**Output 2:**

```
Octal representation of 0 is: 0o0
Octal representation of 1 is: 0o1
Octal representation of 2 is: 0o2
Octal representation of 3 is: 0o3
Octal representation of 4 is: 0o4
```

**Example 3: Conversion from String to Octal**

```
num_str = "21"
num_int = int(num_str)
octal_num = oct(num_int)
print("Octal representation of", num_str, "is:", octal_num)
```

**Output 3:**

```
Octal representation of 21 is: 0o25
```

- The
`oct()`

function returns a string representation of the octal value prefixed with ‘0o’. - It accepts an integer as input and returns its octal equivalent.
- The function is particularly useful in scenarios requiring octal representations, such as low-level programming and permissions manipulation.
