尝试理解 Python 中的 Soundex 算法

Question

What does this number parameter in Soundex function mean?

Code:

import fuzzy
soundex = fuzzy.Soundex(6)

Answer 1

From the source code it looks like it is the output size:

cdef class Soundex:
    cdef int size
    cdef char *map

    def __init__(self, size):
        self.size = size
        ...
        if written == self.size:
            break

Soundex, by default, generates 4-character codes but you seem to be able to change that in this implementation.
