Python library for converting plain text (ASCII) into GSM 7-bit character set?

Question

Is there a python library for encoding ascii data to 7-bit GSM character set (for sending SMS)?

Answer 1

I could not find any library. But I think this should not need a library. Its somewhat easy to do.

Here is Jon Skeet himself on the same topic.

Example:

s = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'

def ascii_to_gsm(ch):
    return bin(65 + s.index(ch))

print ascii_to_gsm('A')
print '--'

binary_stream = ''.join([str(ascii_to_gsm(ch))[2:] for ch in s])
print binary_stream

You can also use dict to store mapping between ASCII and GSM 7-bit character set.
