Python oct() Function with Examples

Python / By

In the previous article, we have discussed Python min() Function with Examples
oct() Function in Python:

The oct() function is used to convert an integer to an octal string.

Python prefixes octal strings with 0o.

Syntax:

oct(number)

Parameters

number: This is required. It is an integer number.

If the value is not an integer (binary, decimal, or hexadecimal), it should implement __index__() to return an integer.

Return Value:

The oct() function takes an integer number and returns an octal string.

Examples:

Example1:

Input:

Given Number = 18

Output:

The given number's{ 18 } Octal Value =  0o22
The oct() function Return Type = <class 'str'>

Example2:

Input:

Given number  = 13
Given binary number  = 0b10
Given hexadecimal number  = 0XB

Output:

The oct(13) value is =  0o15
The oct(0b10) value =  0o2
The oct(0XB) value =  0o13

oct() Function with Examples in Python

Method #1: Using Built-in Functions (Static Input)

Approach:

  • Give the number as static input and store it in a variable.
  • Pass the given number as an argument to the oct() function to get the Octal value of a given number.
  • Store it in another variable.
  • Print the given number’s OctalValue.
  • Print the Return Type of oct() Function using the type() method by passing the oct(given number) as an argument to it.
  • The Exit of the program.

Below is the implementation:

# Give the number as static input and store it in a variable.
gvn_numbr = 18
# Pass the given number as an argument to the oct() function to get the
# Octal value of a given number.
# Store it in another variable.
Octal_valu = oct(gvn_numbr)
# Print the given number's Octal Value.
print("The given number's{", gvn_numbr,
      "} Octal Value = ", Octal_valu)
# Print the return Type of oct() Function using the type() method by passing
# the oct(given number) as an argument to it.
print("The oct() function Return Type =", type(oct(gvn_numbr)))

Output:

The given number's{ 18 } Octal Value =  0o22
The oct() function Return Type = <class 'str'>
oct() For binary and Hexadecimal numbers
# converting decimal to octal
print('The oct(13) value is = ', oct(13))

# converting binary to octal
print('The oct(0b10) value = ', oct(0b10))

# converting hexadecimal to octal
print('The oct(0XB) value = ', oct(0XB))

Output:

The oct(13) value is =  0o15
The oct(0b10) value =  0o2
The oct(0XB) value =  0o13

Method #2: Using Built-in Functions (User Input)

Approach:

  • Give the number as user input using the int(input()) function and store it in a variable.
  • Pass the given number as an argument to the oct() function to get the Octal value of a given number.
  • Store it in another variable.
  • Print the given number’s OctalValue.
  • Print the Return Type of oct() Function using the type() method by passing the oct(given number) as an argument to it.
  • The Exit of the program.

Below is the implementation:

# Give the number as user input using the int(input()) function and store it in a variable.
gvn_numbr = int(input("Enter some random number = "))
# Pass the given number as an argument to the oct() function to get the
# Octal value of a given number.
# Store it in another variable.
Octal_valu = oct(gvn_numbr)
# Print the given number's Octal Value.
print("The given number's{", gvn_numbr,
      "} Octal Value = ", Octal_valu)
# Print the return Type of oct() Function using the type() method by passing
# the oct(given number) as an argument to it.
print("The oct() function Return Type =", type(oct(gvn_numbr)))

Output:

Enter some random number = 10
The given number's{ 10 } Octal Value = 0o12
The oct() function Return Type = <class 'str'>
