Dumb noob q: ASCII value of a character

[Steve Horsley]

How can I get the ASCII value of a character, e.g. I have:

str = "A B"
for index in range(0, len(str)):
value = WHAT_GOES_HERE? (str[index])
print value


and I hope to get:
65
32
66


I know the characters will be printable ASCII.
But how do I get those ASCII character values from the characters???
I can't seem to find it in the library reference

Thanks,
Steve

It's a good idea to read through all the builtin functions, as
documented in http://www.python.org/doc/current/li...built-in-funcs
and keep them in mind.

In this case, ord() (and it's inverse chr()) are what you want.

Hi Steve,

a word of advice: do not use the name of an existing function as identifier
for
a variable ( I am referring to your usage of str as the name of the
variable - you are reassigning it!!!). But back to your question:
What you're looking for is:

s = "A B"
for c in s:
print ord(c)

HTH,

ord.

(And yes, it's a little hard to find. The first time I had to
solve this problem, I used:
[color=blue][color=green][color=darkred]
>>> import string
>>> string.index(st ring._idmap,'A' )[/color][/color][/color]
65

)

Also of note: Strings can be used as iterators, so there's no need to
use that indexing trick:
[color=blue][color=green][color=darkred]
>>> str = "A B"
>>> for char in str:[/color][/color][/color]
.... print ord(char)
....
65
32
66[color=blue][color=green][color=darkred]
>>>[/color][/color][/color]

Thank you everyone who answered.

Also, "for c in s:" - hmmm , still learning fast!
Also, overriding str funcion with a local variable - and STILL learning fast!
