Question

我有一个充满句子的文件，我想用它做一个单字组：

这是我的代码，只收到一个字母，我希望它能得到这个词

old_lines = open("f.final",'r').readlines() 
new_lines = []

for line in old_lines:
    words = line.split()
    new_lines.append(words)

print new_lines

for lines in new_lines:
    c = Counter(str(lines))


with open("final.final", 'w') as f:
    for k,v in  c.items():
        f.write("{} {}\n".format(k,v))

Answer 1

您正在从字符串（即str(lines)）构建计数器，该字符串会对字符串中的每个字符进行计数。您应该直接从列表中构建计数器。这应该针对所有行进行，而不仅仅是最后一行：

with open("f.final") as f, open("final.final", 'w') as out_f:
    # take count of all words from all lines
    c = Counter(word for line in f for word in line.strip().split())

    # write to output file
    for k, v in  c.items():
        out_f.write("{} {}\n".format(k,v))

Python将计数器中的信息传递给文件
