无法在outpu中获取全文

Question

我有两个文本文件，我在|之前匹配了txt1的第二列和txt2的第一列，我只是在下面提到它，如果它们相同的话，我会输出，还有它的描述，一切都很好，但是我没有得到输出中的new line discription，它只是显示了它的第一行。你知道吗

以下是txt1.txt的内容

E5 E7 Bat

以下是txt2.txt的内容：

?E7|E5
Addsadsadsadsadsadsdasd
Sdsdfsdfdsfdsfdfdsfdsfd
AasadsaddccxcvcsAAGCAGT

这是我正在使用的代码

with open('txt1.txt', 'rb') as file1:
    #file1_data = dict(line.split()[1] for line in file1 if line.strip())
    file1_data = [line.split()[1] for line in file1 if line.strip()]
#print file1_data
with open('txt2.txt', 'rb') as file2, open('output.txt', 'wb') as outputfile:
    output = ""
    file2lines = file2.readlines()
    for i in range(len(file2lines)):
        line = file2lines[i]
        if line[0] == '?':
            row = line.strip().split('|')
            key = row[0][1:]
            if key in file1_data:
                output += line + "\t" + file2lines[i+1]
    outputfile.write(output)
outputfile.close()

Getting output

?E7|E5

Required output

?E7|E5

我认为您需要一些状态处理-“在匹配块中”/“不在匹配块中”。我重写了你算法的第二部分：

with open('txt2.txt', 'rb') as file2, open('output.txt', 'wb') as outputfile:
    output = []
    do_block = False
    for line in file2:
        line = line.rstrip()
        if not line: continue
        if line[0] == '?':
            key = line.strip().split('|')[0][1:]
            do_block = key in file1_data
        if do_block:
            output.append(line)
    outputfile.write("\n".join(output))
