我有两个文本文件： Speech.txt 和 Script.txt 。 Speech.txt 包含音频文件的文件名列表，而 Script.txt 包含相关的脚本。 Script.txt 包含所有字符和项目的笔录，但是我只希望特定字符的笔录仅。我想编写一个python脚本，将文件名与脚本进行比较，并返回一个文本文件，其中包含文件路径，文件名，扩展名和由 | 分隔的脚本。
语音样本.txt：
ItemsControlScript.txt示例：
0x000f4a03.wav
0x000f4a07.wav
0x000f4a0f.wav
预期输出：
0x000f4a0f | | And unites the clans against Nilfgaard?
0x000f4a11 | | Of course. He's already decreed new longships be built.
0x000f4a03 | | Thinking long-term, then. Think she'll succeed?
0x000f4a05 | | She's got a powerful ally. In me.
0x000f4a07 | | Son's King of Skellige. Congratulations to you.
代码（正在进行中）：
C:/Speech/0x000f4a03.wav|Thinking long-term, then. Think she'll succeed?
C:/Speech/0x000f4a07.wav|Son's King of Skellige. Congratulations to you.
C:/Speech/0x000f4a0f.wav|And unites the clans against Nilfgaard?
以上代码似乎仅适用于Speech.txt的第一行，然后停止。我希望它遍历整个文件，即第2行，第3行...等。我还没有弄清楚如何将结果输出到文本文件中。我目前只能打印出结果。任何帮助将不胜感激！

您可以使用readlines（）方法将这些行加载到列表中，然后对其进行迭代。这样就避免了Kenteep Singh Sidhu正确验证了指针到达文件末尾的问题。
f1=open(r'C:/Speech.txt',"r", encoding='utf8')
f2=open(r'C:/script.txt',"r", encoding='utf8')
lines1 = f1.readlines()
lines2 = f2.readlines()
f1.close()
f2.close()
with open("output.txt","w") as outfile:
for line1 in lines1:
for line2 in lines2:
if line1[0:10]==line2[0:10]:
outfile.write('C:/Speech/' + line2[0:10] + '.wav' + '|' + line2[26:-1],"/n")

我将把Script.txt的内容读入字典，然后使用该字典对Speech.txt中的行进行迭代，仅打印存在的行。这样可以避免多次迭代文件的需要，如果文件很大，这可能会很慢。
演示：
from pathlib import Path
with open("Speech.txt") as speech_file, open("Script.txt") as script_file:
script_dict = {}
for line in script_file:
key, _, text = map(str.strip, line.split("|"))
script_dict[key] = text
for line in map(str.strip, speech_file):
filename = Path(line).stem
if filename in script_dict:
print(f"C:\Speech\{line}|{script_dict[filename]}")
输出：
C:\Speech\0x000f4a03.wav|Thinking long-term, then. Think she'll succeed?
C:\Speech\0x000f4a07.wav|Son's King of Skellige. Congratulations to you.
C:\Speech\0x000f4a0f.wav|And unites the clans against Nilfgaard?
使用With Statement Context Managers打开文件也容易得多，因为您不需要调用.close()来关闭文件，因为它可以为您处理。
我还使用pathlib.PurePath.stem从您的.wav文件中获取文件名。我发现它比os.path.basename os.path.spltext函数更易于使用。尽管这是个人喜好，并且一切正常。
如果我们想将输出写入文本文件，可以使用mode="w"以写入模式打开另一个输出文件：
from pathlib import Path
with open("Speech.txt") as speech_file, open("Script.txt") as script_file, open("output.txt", mode="w") as output_file:
script_dict = {}
for line in script_file:
key, _, text = map(str.strip, line.split("|"))
script_dict[key] = text
for line in map(str.strip, speech_file):
filename = Path(line).stem
if filename in script_dict:
output_file.write(f"C:\Speech\{line}|{script_dict[filename]}\n")
output.txt
C:\Speech\0x000f4a03.wav|Thinking long-term, then. Think she'll succeed?
C:\Speech\0x000f4a07.wav|Son's King of Skellige. Congratulations to you.
C:\Speech\0x000f4a0f.wav|And unites the clans against Nilfgaard?
您可以查看文档中的Reading and Writing Files，以获取有关如何在python中读写文件的更多信息。

使用max也是另一种方法，因为这似乎是您的典型联接问题。
pandas然后只需选择所需的列并将其保存。
import pandas as pd
df = pd.read_csv('speech.txt', header=None, names=['name'])
df1 = pd.read_csv('script.txt', sep='|', header=None, names=['name', 'blank', 'description'])
df1['name'] = df1.name.str.strip() + '.wav'
final = pd.merge(df, df1, how='left', left_on='name', right_on='name')
final['name'] = 'C:/Speech/' + final['name']
print(final)
name blank description
0 C:/Speech/0x000f4a03.wav Thinking long-term, then. Think she'll succeed?
1 C:/Speech/0x000f4a07.wav Son's King of Skellige. Congratulations to you.
2 C:/Speech/0x000f4a0f.wav And unites the clans against Nilfgaard?

对于Speech.txt文件的每一行，您需要检查Script.txt文件中是否存在。考虑到Script.txt的内容适合存储在内存中，您应该加载其内容以避免每次都读取它。
一旦加载Script.txt的内容，您只需处理Speech.txt的每一行，在字典中进行搜索，并在需要时进行打印。
接下来，我提供代码。请注意：
python -O script.py os.path.splittext(var)[0]从文件名中删除扩展名strip处理每行以摆脱空格/换行符。代码：
