Conversion of various underlying types in Python, binary, octal, decimal, hex

All types in Python exist as objects.

There is no char type in Python, only a string type, which makes it very inconvenient for us to convert the char type to integer, but Python already provides built-in functions for these transformations.

In Python, in addition to Integer, the other binary can only be represented by a string.

1 int ()

Binary, octal, 16-binary can be converted to decimal integer

>>> int (' 1111 ', 2) 15>>> int (' F ', +) 15>>> int (' 17 ', 8) 15

2 Chr ()

Convert an integral type to a character

>>> chr ' Z '

3 Ord ()

Convert a character to an integral type

>>> Ord (' Z ') 90

4 Hex ()

Convert decimal to hexadecimal

>>> Hex (255) ' 0xFF '

5 Oct ()

Convert Decimal to Octal

>>> Oct (255) ' 0377 '

6 bin ()

Convert decimal into binary

>>> Bin (255) ' 0b11111111 '
