Python Decimal to Binary, Octal, Hexadecimal
Python3 ExamplesThe following code is used to convert decimal to binary, octal, and hexadecimal:
Example (Python 3.0+)
# -*- coding: UTF-8 -*-
# Filename : test.py
# author by : www.example.com
# Get user input decimal number
dec = int(input("Enter a number:"))
print("Decimal number:", dec)
print("Converted to binary:", bin(dec))
print("Converted to octal:", oct(dec))
print("Converted to hexadecimal:", hex(dec))
Executing the above code produces the following output:
python3 test.py 输入数字：5 十进制数为：5 转换为二进制为： 0b101 转换为八进制为： 0o5 转换为十六进制为： 0x5
The following examples show how to convert between different bases. You can modify the input base value and the output base format as needed.
Binary Conversion Example
Example
binary_number = '101010'
decimal_number = int(binary_number, 2) # Convert binary to decimal
octal_number = oct(decimal_number) # Convert decimal to octal
hexadecimal_number = hex(decimal_number) # Convert decimal to hexadecimal
print('Binary number:', binary_number)
print('Converted to decimal:', decimal_number)
print('Converted to octal:', octal_number)
print('Converted to hexadecimal:', hexadecimal_number)
decimal_number = int(binary_number, 2) # Convert binary to decimal
octal_number = oct(decimal_number) # Convert decimal to octal
hexadecimal_number = hex(decimal_number) # Convert decimal to hexadecimal
print('Binary number:', binary_number)
print('Converted to decimal:', decimal_number)
print('Converted to octal:', octal_number)
print('Converted to hexadecimal:', hexadecimal_number)
Output result:
二进制数: 101010 转换为十进制: 42 转换为八进制: 0o52 转换为十六进制: 0x2a
Octal Conversion Example
Example
octal_number = '52'
decimal_number = int(octal_number, 8) # Convert octal to decimal
binary_number = bin(decimal_number) # Convert decimal to binary
hexadecimal_number = hex(decimal_number) # Convert decimal to hexadecimal
print('Octal number:', octal_number)
print('Converted to decimal:', decimal_number)
print('Converted to binary:', binary_number)
print('Converted to hexadecimal:', hexadecimal_number)
decimal_number = int(octal_number, 8) # Convert octal to decimal
binary_number = bin(decimal_number) # Convert decimal to binary
hexadecimal_number = hex(decimal_number) # Convert decimal to hexadecimal
print('Octal number:', octal_number)
print('Converted to decimal:', decimal_number)
print('Converted to binary:', binary_number)
print('Converted to hexadecimal:', hexadecimal_number)
Output result:
八进制数: 52 转换为十进制: 42 转换为二进制: 0b101010 转换为十六进制: 0x2a
Hexadecimal Conversion Example
Example
hexadecimal_number = '2a'
decimal_number = int(hexadecimal_number, 16) # Convert hexadecimal to decimal
binary_number = bin(decimal_number) # Convert decimal to binary
octal_number = oct(decimal_number) # Convert decimal to octal
print('Hexadecimal number:', hexadecimal_number)
print('Converted to decimal:', decimal_number)
print('Converted to binary:', binary_number)
print('Converted to octal:', octal_number)
decimal_number = int(hexadecimal_number, 16) # Convert hexadecimal to decimal
binary_number = bin(decimal_number) # Convert decimal to binary
octal_number = oct(decimal_number) # Convert decimal to octal
print('Hexadecimal number:', hexadecimal_number)
print('Converted to decimal:', decimal_number)
print('Converted to binary:', binary_number)
print('Converted to octal:', octal_number)
Output result:
十六进制数: 2a 转换为十进制: 42 转换为二进制: 0b101010 转换为八进制: 0o52Other Extensions
