Question

大家好我输出有点问题我的文件带有时间戳，这是我的代码

input_file  = open('DVBSNOOP/epg_slo_sort.txt', "r") # read
output_file = open('SORT/epg_slo_xml.txt', "w") # write 

for line in input_file:
    line = re.sub(r"\d{8}:|\d{7}:|\d{6}:|\d{5}:|\d{4}:","", line) # remove nubers from start line example --> 10072633: etc...
    line = line.replace("[=  --> refers to PMT program_number]","").replace("Service_ID:","Program") # remove =  --> refers to PMT program_number] and replace Service_ID to Program
    line = line.replace("0xdce","").replace("Start_time:","Start") # remove 0xdce and change Start_time to start
    line = line.replace("0x0","") # remove 0xdce 
    line = line.replace("event_name:","Title") # change to Title from event_name
    line = line.replace("Program: 14 (00e)","") # remove program 14 does not exist
    line = line.replace("-- Charset: ISO/IEC 8859  special table","") # remove -- Charset: ISO/IEC 8859  special table
    line = line.replace("-- Charset: ISO/IEC   special table","")# remove -- Charset: ISO/IEC   special table
    line = line.replace("[=","").replace("]","") # remove [=]
    line = line.replace("Duration:","Duration").replace("0x00","").replace("0x000","").replace("0x","")
    line = line.replace('"..',"").replace('"',"").replace(" . . .","").replace("-","") # remove ".."
    line = re.sub(r"Start: \d{2}|\d{4}|\d{3}|\d{7}\d{9}\d{6}","",line) # remove numbers after
    line = re.sub(r"Duration: \d{2}|\d{6}|\d{7}|d{5}\d{8}\d{4}|\d{3}|\d{9}","Duration",line) # remove numbers affter data
    line = re.sub(r"^//","",line) # remove / /
    line = re.sub(r"\([^)]*\)","",line) # remove brackets
    line = re.sub(r"Program 14","",line) # remove program 14
    output_file.write(line) # write to file

我希望我的输出像epg_slo_sort(M;D;Y:Time).txt。

要生成带有时间戳的文件名，请使用time module中的strftime()来获取必要格式的时间并将其与文件名模式连接起来：

import time
current_time = time.strftime("%m.%d.%y %H:%M", time.localtime())
output_name = 'SORT/epg_slo_xml%s.txt' % current_time
output_file = open(output_name, "w")

Answer 2

这是你正在寻找的吗？它以您指定的格式返回包含所需时间信息的字符串：

 import time
 tme=time.localtime()
 timeString=time.strftime("%m,%d,%y,%H:%M:%S", tme)

现在您只需要按照您想要的方式对其进行格式化并附加到文件名。有很多方法可以做到，一种非常粗略但有效的方法是：

 outFileName='epg_slo_xml'+timeString+'.txt'

另一种方法是做这样的事情：

outFileName='epg_slo_xml{}.txt'.format(timeString)

但这仅适用于Python 2.7及更高版本。我还没有使用它（但是）我认为Python 3.X是相似的。
