?i FdZddlmZddld d dZd d dZd d dZd d dZy) aThe ISO 7064 Mod 37, 36 algorithm. The Mod 37, 36 algorithm uses an alphanumeric check digit and the number itself may also contain letters. >>> checksum('A12425GABC1234002M') 1 >>> calc_check_digit('A12425GABC1234002') 'M' >>> validate('A12425GABC1234002M') 'A12425GABC1234002M' By changing the alphabet this can be turned into any Mod x+1, x algorithm. For example Mod 11, 10: >>> calc_check_digit('00200667308', alphabet='0123456789') '5' >>> validate('002006673085', alphabet='0123456789') '002006673085' ) annotations)*c|t|}|dz}|D]&}|xs|dz|dzz|j|z|z}(|S)zCCalculate the checksum.
