Python 比较两个文本文件并将匹配值写入文本文件

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，Script.txt包含相关的成绩单。Script.txt包含所有字符和项目的成绩单，但是我只想要特定字符的成绩单。我想编写一个python脚本，将文件名与转录本进行比较，并返回一个文本文件，其中包含文件路径、文件名、扩展名和以|分隔的转录本

Speech.txt示例：

Script.txt的示例：

预期产出：

正在进行的代码工作：

上面的代码似乎只适用于Speech.txt中的第一行，然后停止。我希望它贯穿整个文件，即第2行、第3行……等等。我还没有弄清楚如何将结果输出到文本文件中。我现在只能把结果打印出来。任何帮助都将不胜感激

您可以使用readlines方法将行加载到列表中，然后对其进行迭代。这避免了Kuldeep Singh Sidhu正确标识到达文件末尾的指针的问题

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")

我会将Script.txt的内容读入字典，然后将此字典用作迭代Speech.txt中的行，只打印存在的行。这避免了多次迭代文件的需要，如果您有大文件，这可能会非常慢

演示：

输出：

它也更容易用于打开文件，因为您不需要调用.close来关闭文件，因为它会为您处理这些

我还从你的.wav文件中获取文件名。我发现这比函数更容易使用。虽然这是个人喜好，一切都会奏效

如果要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：

output.txt

您可以从文档中查看有关如何在python中读取和写入文件的更多信息

使用pandas也是另一种方法，因为这似乎是典型的连接问题

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?

然后，只需选择所需的列并将其保存即可

final = final[['name', 'description']]
final.to_csv('some_name.csv', index=False, sep='|')

对于Speech.txt文件的每一行，您需要检查它是否存在于Script.txt文件中。考虑到Script.txt的内容适合内存，您应该加载它的内容，以避免每次都读取它

加载Script.txt的内容后，只需处理Speech.txt的每一行，在字典中搜索并在需要时打印即可

接下来，我提供代码。请注意：

我添加了调试信息。您可以通过执行python-oscript.py来隐藏它 我使用os.path.splittextvar[0]从文件名中删除扩展名 我剥离每一条处理过的线，以消除空格/换行符。 代码：
