Example:

number = 10
number_bin = bin(number)
number_oct = oct(number)
number_hex 
 
= hex(number)
print("--------------- 十進制轉換 -----------------------------")
print(number, "所對應的二進制表示為：", number_bin)
print(number, "所對應的八進制表示為：", number_oct)
print(number, "所對應的十六進制表示為：", number_hex)
print("--------------- 二進制轉換 -----------------------------")
print(number_bin, "所對應的十進制表示為：", int(number_bin, 2))
 
print(number_bin, "所對應的八進制表示為：", oct(int(number_bin, 2)))
print(number_bin, "所對應的十六進制表示為：", hex(int(number_bin, 2)))
print("--------------- 八進制轉換 -----------------------------")
print(number_oct, "所對應的十進制表示為：", int(number_oct, 8))
print(number_oct, "所對應的二進制表示為：", bin(int(number_oct, 8)))
print(number_oct, "
 
所對應的十六進制表示為：", hex(int(number_oct, 8)))
print("--------------- 十六進制轉換 -----------------------------")
print(number_hex, "所對應的十進制表示為：", int(number_hex, 16))
print(number_hex, "所對應的二進制表示為：", bin(int(number_hex, 16)))
print(number_hex, "所對應的八進制表示為：", oct(int(number_hex, 16)))
