Different syntax and transformations in Python

Different ways of writing in the system

• Octal (octal) 0o377
• Hex (hex) 0xFF
• Binary binary (binary) 0b11111111

Conversions between different binaries

Python provides three built-in functions that can be used to convert between different binaries.

>>> oct(255), hex(255), bin(255)(‘0o377‘, ‘0xff‘, ‘0b11111111‘)

You can also use the int function to turn a string into a numeric value

>>> int(‘255‘), int(‘0xFF‘, 16)(255, 255)

In addition to the ability to use eval, the function is similar to the int function, but its parameters are Python code.

>>> eval(‘255‘), eval(‘0xFF‘)(255, 255)

Of course, you can also use the formatted output of a string

>>> ‘{0:0}, {1:x}, {2:b}‘.format(255, 255, 255)‘255, ff, 11111111‘>>> ‘%o, %x, %X‘ % (255, 255, 255)‘377, ff, FF‘
