I am new to python. How can I compare if 2 files has duplicate entries
in python?
Is there an example for that? What if the files are big and I don't
want to read the whole file in memory.
Thank you.

Now that's definitely what I'm looking for! Thanks!
By the way, was this line
In [5]: C = repeat(B, [1,2,1], axis=-1)
supposed to have a positive 1 value for axis? It works either way, I
see. Is it like a lookup, where an index of -1 returns the last value?
If that were true, I supposed the eval

Hey Gerard,
Thanks for the suggestion! It took me a while to figure out how to get
this to work. Two things were important: I needed to use the
matrixmultiply() function, and the order of the two matrices being
multiplied is critcial. Here's how I got the example to work.
>>> from Numeric import

Hello Pythonistas!
I'm looking for a way to duplicate entries in a symmetrical matrix
that's composed of genetic distances. For example, suppose I have a
matrix like the following:
ABC
A 0.00 0.50 1.00
B 0.50 0.00 0.50
C 1.00 0.50 0.0
Thanx Mike, My problem solved !! I loaded the entire file contnets into
list and my job was a piece of cake after that.

Hi there, I'm just curious to know as to how the changes you have
suggested will solve the problem. Instead of appending (what I was
doing), now we are opening and storing the files in 'binary' format.
All the other entries in my file will be gone when I write into the
file again.
What I actuall n

Now, my problem is after finding the entry in the file, I want to make
changes to the 'values' under the searched '

Dear Python Gurus:
I am a very new Python user, would really appreciate your help.
I used Python to write a web form for users to enter. The underlined database is Oracle. One validation needs to enforce to eliminate duplicates entries. For example: one customer ID can only be entered only on
16 matches
