从文本文件中收集特定行[关闭]

Question

sample of the txt file

我想从具有NVSS关键字的txt文件中提取整行，并将其导出为新的txt文件，但我不知道如何执行此操作。谢谢

Answer 1

要将包含“NVSS”的每一行提取到新文件中：

with open('infile.txt', 'r') as infile, open('outfile.txt', 'w') as outfile:
    for line in infile:
        if 'NVSS' in line:
            outfile.write(line)
