将句子的长度附加到文件中

Question

我找到了长度和索引，我想将它们全部保存到新文件中：

示例：索引句子长度

我的代码

file = open("testing_for_tools.txt", "r")
lines_ = file.readlines()
for line in lines_:
    lenght=len(line)-1
    print(lenght)
for item in lines_:
    print(lines_.index(item)+1,item)

输出：

64
18
31
31
23
36
21
9
1
1 i went to city center, and i bought xbox5 , and some other stuff

2 i will go to gym !

3 tomorrow i, sill start my diet!

4 i achive some and i need more ?

5 i lost lots of weights؟

6 i have to , g,o home,, then sleep  ؟

7 i have things to do )

8 i hope so

9 o

所需的输出并保存到新文件：

1 i went to city center, and i bought xbox5 , and some other stuff 64
2 i will go to gym ! 18

Answer 1

这可以使用以下代码实现。注意 with ... as f 的使用，这意味着我们不必担心在使用后关闭文件。此外，我使用了 f-strings（需要 Python 3.6）和 enumerate 来获取行号并将所有内容连接成一个字符串，该字符串被写入输出文件。

with open("test.txt", "r") as f:
    lines_ = f.readlines()

with open("out.txt", "w") as f:
    for i, line in enumerate(lines_, start=1):
        line = line.strip()
        f.write(f"{i} {line} {len(line)}\n")

输出：

1 i went to city center, and i bought xbox5 , and some other stuff 64
2 i will go to gym ! 18

如果您想根据长度对行进行排序，您可以将以下行放在第一个 with 块之后：

lines_.sort(key=len)

这将给出输出：

1 i will go to gym ! 18
2 i went to city center, and i bought xbox5 , and some other stuff 64
