python實現文本中單詞個數統計

                count[word] += 1
            else:

        line_counts += 1
        word_counts += len(words)
        character_counts += len(line)
    for index, item in count.items():
        print("單詞",index,"個數=",item)

print("行數 ", line_counts)
print("單詞的個數 ", word_counts)
print("字節數 ", character_counts)
