The integer "050" is in octal notation and represents the decimal integer "40". "080" is invalid because there is no "8" in octal.

Here is a regex solution:
This method uses string method split:Code:import re pattern = re.compile(r"^\D+?_\D+?_(.+?)_") def sort_on_TS(a, b): return cmp(pattern.match(a).group(1), pattern.match(b).group(1)) for item in sorted(file_list, sort_on_TS): print item
...Code:def sort_on_TS(a,b): return cmp(a.split("_")[2], b.split("_Leave a comment:

Here is another possibility:
Code:window.grab_release() window.withdraw() # do stuff here # restore the window window.deiconify() window.grab_set()

You are welcome. Sometimes the obvious solution is the hardest to see.Leave a comment:

Move your first guess under the while statement. Initialize tries to 0. I modified your code for Python 2.7:
...Code:import random print "Welcome to guess my number game!!!" print "Please enter the number between 1 and 100" number = random.randint(1, 100) print number max_guess = 5 tries = 0 while True: guess = int(raw_input("Take a guess:Leave a comment:

You are iterating over the lines in the file twice. Try eliminating one of them. It is possible OrderedDict may be slower than a for loop. I don't know one way or the other. You can use module timeit to check different methods.Leave a comment:

No, write to the file outside of the for loop:
Code:outFile.write("\n".join(log)) inputFile.close() outFile.close()Leave a comment:

The error is self explanatory. Try fixing the indentation error in that file.Leave a comment:

One way is to create a StringVar and assign it to the entry field textvariable option. Use the StringVar object's method set to assign a value. Use a lambda in the browse button command assignment so you can pass the StringVar as an argument for reassignment. You should not need a global variable.

Try writing to the file one time.

The interpreter is attempting to execute the except clause because of an error and it is finding a NameError in the except clause. Idetifier "socket" is not defined. Try removing "socket.err or" and run again to see what the error actually is.Leave a comment:

Use a for loop and conditionally append to a list.
...Code:data = """Jan 1 02:32:40 hello welcome to python world Jan 1 02:32:40 hello welcome to python world Mar 31 23:31:55 learn python Mar 31 23:31:55 learn python be smart Mar 31 23:31:56 python is good scripting language Jan 1 00:00:01 hello welcome to python world Jan 1 00:00:02 hello welcome to python world Mar 31 23:31:55 learn

Built-in funcation eval: Python documentation for eval
The function could potentially evaluate malicious code, therefore its use if sometimes frowned upon. A regex solution could potentially be a more robust but complicated solution.

There may be a better way.
Code:>>> my_string = '(1, 2) (3, 4)' >>> eval(my_string.replace(") (", "),(")) ((1, 2), (3, 4)) >>> a,b = eval(my_string.replace(") (", "),(")) >>> a (1, 2) >>> b (3, 4) >>>Leave a comment:

You knew the upper and lower values in your original post. How did you know them? If you are dealing with dates and times instead of strictly formatted data, look into using the time and datetime modules. Example of creating a datetime object from the date/time string:
From there...Code:>>> datetime.datetime.strptime("Jun 6 17:58:13", "%b %d %H:%M:%S") datetime.datetime(1900, 6, 6, 17, 58, 13) >>>Leave a comment:

To achieve the output you need, use re to determine an integer representing the seconds and compare to the lower and upper boundaries. Here's an example:
...Code:import re data = """Jun 6 17:58:13 other strings Jun 6 17:58:13 other strings Jun 6 17:58:14 other strings Jun 6 17:58:14 other strings Jun 6 17:58:15 other strings Jun 6 17:58:15 other strings Jun 6 17:58:15 other

You could do something like this:
...Code:import Tkinter top = Tkinter.Tk() def FstartCallBack(): top.grab_release() top.withdraw() # run your script here B.pack_forget() L = Tkinter.Label(top, text="Activated") L.pack() top.title("Action Complete") top.minsize(width=250, height=20) top.wm_deiconify()Leave a comment:

In your original post, you stated you wanted to display the highest score.
enumerate is a built-in function. i and item are identifiers of the values returned by enumerate. From Python help:
"enumerate(sequ ence[, start=0])...
Return an enumerate object. sequence must be a sequence, an iterator, or some other object which supports iteration. The next() method of the iterator returned by enumerate() returns a tuple containingLeave a comment:

Is this what you want to do?
Code:>>> results = [["Ben", 15, 18,25, 6, 9], ["George", 25, 35, 85, 12, 9], ["Evie", 2, 54, 84, 62,18]] >>> for i, item in enumerate(results): ... results[i] = [item[0], max(item[1:])] ... >>> sorted(results) [['Ben', 25], ['Evie', 84], ['George', 85]] >>>
