I think there's an easy explanation for that, which is that eryksun
probably just created a variable "s" but didn't show the co

Believe it or not, a change in two characters should make this even faster. :)
Change the line:
file_list = [i[:-1] for i in my_list.readlines()]
to:
file_list = {i[:-1] for i in my_list.readlines()}
The change is to use a "set comprehension" instead of a "list
comprehension". Sets
It is probably better to store your key file in memory
then loop over the large data file and check the
line against each key. Better to check 2000 data
keys in memory for one loop of the data file.
That way you only read the key file and data file
once each - 502,000 reads instead of a billion.
Hi Alan,
I had done what you suggested here, I also tried creating another file for
that snipet of the code to see if that section works. The other file works,
but I am not able to figure out why the original one doesn't work.
The variable here is entrynumberspeciesvar
Code:
from Tkinter import *

Hi,
I am trying to create a label and an entry widget. I am not able to
understand as to how to access the value input by the user in the entry
widget.
Label(frame1, text = "Number of species:").grid(row=0, column = 1, sticky=W)
entrynumberspecies = Entry(frame1)
entrynumberspecies.grid(row=0, co
