How to get the ASCII value of a character

Question

How do I get the ASCII value of a character as an int in Python

User · Answer

Note that ord   doesn t give you the ASCII value per se  it gives you the numeric value of the character in whatever encoding it s in  Therefore the result of ord       can be 228 if you re using Latin-1  or it can raise a TypeError if you re using UTF-8  It can even return the Unicode codepoint instead if you pass it a unicode    gt  gt  gt  ord u     12354

From here   The function ord   gets the int value of the char  And in case you want to convert back after playing with the number  function chr   does the trick    gt  gt  gt  ord  a   97  gt  gt  gt  chr 97   a   gt  gt  gt  chr ord  a     3   d   gt  gt  gt   In Python 2  there was also the unichr function  returning the Unicode character whose ordinal is the unichr argument   gt  gt  gt  unichr 97  u a   gt  gt  gt  unichr 1234  u  u04d2   In Python 3 you can use chr instead of unichr   ord   - Python 3 6 5rc1 documentation ord   - Python 2 7 14 documentation

The accepted answer is correct  but there is a more clever efficient way to do this if you need to convert a whole bunch of ASCII characters to their ASCII codes at once  Instead of doing         for ch in mystr      code   ord ch    or the slightly faster   for code in map ord  mystr     you convert to Python native types that iterate the codes directly  On Python 3  it s trivial   for code in mystr encode  ascii      and on Python 2 6 2 7  it s only slightly more involved because it doesn t have a Py3 style bytes object  bytes is an alias for str  which iterates by character   but they do have bytearray     If mystr is definitely str  not unicode for code in bytearray mystr      If mystr could be either str or unicode for code in bytearray mystr   ascii      Encoding as a type that natively iterates by ordinal means the conversion goes much faster  in local tests on both Py2 7 and Py3 5  iterating a str to get its ASCII codes using map ord  mystr  starts off taking about twice as long for a len 10 str than using bytearray mystr  on Py2 or mystr encode  ascii   on Py3  and as the str gets longer  the multiplier paid for map ord  mystr  rises to  6 5x-7x   The only downside is that the conversion is all at once  so your first result might take a little longer  and a truly enormous str would have a proportionately large temporary bytes bytearray  but unless this forces you into page thrashing  this isn t likely to matter

To get the ASCII code of a character  you can use the ord   function   Here is an example code   value   input  Your value here     list  ord ch  for ch in value  print list    Output   Your value here  qwerty  113  119  101  114  116  121
