## Python oct() function

oct() function is a library function, it is used to get the octal value of a given number, it accepts an integer number and returns its octal value in string format.

Syntax:

```    oct(number)
```

Parameter(s): number – an integer number whose value to be converted in an octal number.

Return value: str – it returns the converted octal value of number in string format.

Example:

```    Input:
num = 12345

print("octal value of ", num, " is = ", oct(num))

Output:
octal value of  12345  is =  0o30071
```

Example 1: Python code to convert a number in octal format

```# python code to demonstrate example of
# oct() number

# number
num = 12345
print("octal value of ", num, " is = ", oct(num))

num = 0
print("octal value of ", num, " is = ", oct(num))

num = 2712
print("octal value of ", num, " is = ", oct(num))
```

Output

```octal value of  12345  is =  0o30071
octal value of  0  is =  0o0
octal value of  2712  is =  0o5230
```

Example 2: Python code to print the returns type of oct() function and also test function with wrong input

```# python code to demonstrate example of
# oct() number

# number
num = 12345

# printing return type of the function oct()
print("return type is: ", type(oct(num)))

# testing with invalid values
print(oct(10.23))  # returns error because it's a float values
```

Output

```return type is:  <class 'str'>
Traceback (most recent call last):
File "/home/main.py", line 11, in <module>
print(oct(10.23))  # returns error because it's a flaot values
TypeError: 'float' object cannot be interpreted as an integer
```
