        文本的行数，字符的总数，单词的数量和出现的频率，特殊字符的统计。

# -*- cofing: utf-8 -*-
import os
import sys
import collections
import string

script_name = sys.argv[0]

res = {
    "total_lines":"",
    "total_characters":"",
    "total_words":"",
    "unique_words":"",
    "special_characters":""
}

try:
    textfile = sys.argv[1]
    with open(textfile, "r", encoding = "utf_8") as f:

        data = f.read()
        res["total_lines"] = data.count(os.linesep)
        res["total_characters"] = len(data.replace(" ","")) - res["total_lines"]
        counter = collections.Counter(data.split())
        d = counter.most_common()
        res["total_words"] = sum([i[1] for i in d])
        res["unique_words"] = len([i[0] for i in d])
        special_chars = string.punctuation
        res["special_characters"] = sum(v for k, v in collections.Counter(data).items() if k in special_chars)

except IndexError:
    print('Usage: %s TEXTFILE' % script_name)
except IOError:
    print('"%s" cannot be opened.' % textfile)

print(res)
