谢谢大家发帖。

请允许我详细说明我的需要。我正在解析包含Wi-Fi频道的文本文件。我试图获得频道发生的时间。

我的文本文件(file_parse.txt)具有：

Extra: Age: 1806打开(r“C：\ Temp \ file_parse.txt”)作为文件名：

regex = re.compile("[C|c]hannel:[0-9]+")

count = 0

lst = []

new_lst =[]

for line in filename.readlines():

if regex.search(line):

count += 1

lst.append(line)

new_lst = [(lst[i].split(":"))for i in range(len(lst))]

integer_lst = [int(new_lst[firstElement][1]) for firstElement in range(len(new_lst))]

def channel_count(lst):

dct = {}

for num in lst:

dct[num] = lst.count(num)

print('There are/is {1} channel {0} '.format(num, dct[num]))channel_count(integer_lst)

例外输出：

有/是2频道161

有/是1个频道40

有更好的方法吗？
