我有一个名为“输入”的文件夹，其中包含以“.measbu”或“.info”扩展名结尾的文本文件（例如，c.171203fl.so.power.simu.measbu 和 s.170210.所以.power.info)
.measbu 文本文件包含如下所示的地图：

我希望 Python 遍历“输入”文件夹中的每个 .measbu 和 .info 文件并提取地图并将它们写入一个名为“maps.txt”的单独文件。我考虑搜索“频道”和“总功率”，因为这些词/短语出现在每张地图上方（.measbu 文件中的“频道”，.info 文件中的“总功率”），然后复制该行以及下面的 50 行，因为每张地图大约有 50 行长。
到目前为止我的代码：
import os
for filename in os.listdir('inputs'):
fn = 'inputs/'+filename
for line in open(fn, 'r'):
line.find('channel' or 'total power')
open('maps.txt', 'w').write(line)
但它只是将日期“13-FEB-17 10:04:39”写入 maps.txt，仅此而已，我不确定如何复制并粘贴每个“频道”查找下方的 50 行'或'总功率'。
文件中只有一行的原因是每次您以
maps.txtwmaps.txtmaps.txt例如：
import os
dirname = 'inputs'
phrases = ["total power", "channel"]
with open('maps.txt', 'w', encoding='utf8') as outfile:
for filename in os.listdir(dirname):
fn = os.path.join(dirname, filename)
with open(fn, 'r', encoding="utf8") as infile:
line = next(infile)
if any([phrase in line for phrase in phrases]):
contents = line + infile.read()
outfile.write(contents + ("\n" * 2))
补充说明：
line.find('channel' or 'total power')'channel' or 'total power'channelline.find('channel')如前所述，在
'w'最好使用
withos.path.joins
