Python - Sort files based on timestamp encoded in the filename
I have a list which contains list of file names, i wanted to sort list of those files based on timestamp encoded in file names.
Note: In file, Hello_Hi_2015-02-20T084521_14245 43480.tar.gz --> 2015-02-20T084521 represents as "year-moth-dayTHHMMSS" ( Based on this i wanted to sort )
Input file below:
file_list = ['Hello_Hi_2015-02-20T084521_14245 43480.tar.gz',
'Hello_Hi_2015-02-20T095845_14245 43481.tar.gz',... -
@bvdet: Thank you for your help!!! This is working but still there is performance issue whenever input file size is more....
Could you please take a look into below code...
...Code:def remove_Duplicate_Lines(inputfile, outputfile): with open(inputfile) as fin, open(outputfile, 'w') as out: lines = (line.rstrip() for line in fin) unique_lines = OrderedDict.fromkeys( (line for line in lines if line)Leave a comment:

@bvet: You mean something like below:
Pls correct...Code:inputFile = open("in.txt", "r") outFile = open("out.txt", "w") log = [] for line in inputFile: if line in log and line[0:5] != "Jan 1": pass else: log.append(line) outFile.write("\n".join(log)) inputFile.close() outFile.close()Leave a comment:

@bvdet: Thanks you very much!! I have already been tried this solution but here the problem is if the input message file size is more then it takes more time....
Below is the program which I have tried:
...Code:inputFile = open("in.txt", "r") log = [] for line in inputFile: if line in log and line[0:5] != "Jan 1": pass else: log.append(line)Last edited by bvdet; Jul 15 '15, 07:55 PM. Reason: Fix code tags. Tag [code] should be before code and closing tag [/code] after code.Leave a comment:

Extract Values between two strings in a text file using python
Lets say I have a Text file (input_file.txt , file size is ~10GB ).
Now I need to write a Python code which will read the text file and copy the contents between Start and end to another file.
I wrote the following code.
...Code:import re with open(r'C:\Python27\log\master_input.txt', 'r') as infile, open(r'C:\Python27\log\output', 'w') as outfile: copy = False for
