thanks for your guidance. RE is one of the hardest topic to understand in python.

sorry for confusion. i tried to understand your code by doing a print. for eg:

Code:

p=re.compile('   " *(.*) \((.*), (.*), (.*), (.*)\)," &.*') 
print p

which printed:
<_sre.SRE_Mat ch object at 0x02B5C800>

and

Code:

    m=p.match(line)
    print m

wow only a few lines of codes. i dont get it regular expression, it is hard.
dont understand:
1)p=re.compile( ' " *(.*) \((.*), (.*), (.*), (.*)\)," &.*')
2)m=p.match(lin e), what does match line mean?
3)m.group(i), what does it group?
i tried to print but it only print address.

thanks

apologies for confusion.
general rules:
1) the first line inside input.txt (as attached in the first post):
-- num cell port function safe [ccell disval rslt]
i just need num cell port function safe ccell
however my script below couldnt get this so i skip the line. it will be great if you can show me.

2) i'm trying to convert the line inside the input.txt
"17 (BC_1, CLK, input, X),"...

hi, thanks for your f/back.
would like to check whether the last line print is a typo? and also in the for loop, there is a print, ?
i was thinking of doing:

Code:

for line in lines:
    a=line.split('-')[0]
    print a
    for b in a: 
        print b,
    print

i found it but the leading zeroes are being truncated.
i want it to be: 0x0000001800000 400000000000000 000000000000000 000000000000000 000000L

>>> array0='0000001 800000400000000 0000000000'
>>> array1='0000000 000000000000000 0000000000'
>>> array=array0+ar ray1
>>> a=int(array,16)
>>> print a

thanks for your advice. :)

i notice the code extracts until 128x4=512. there are 8 characters being truncated. total there are 520. how do i resolve this? tq

sorry i didnt mention that i'm using Python 2.5 and Win XP. would like to check whether next() work for Python 2.5, i thought i read it somewhere it doesnt. anyway, i tried the code, it didnt complain any error. so i guess it works on Python 2.5 too..
i have a more complex data file as attached and i modified the code to be:

Code:

f = open("test2.txt") 
f.next() 
dataList = [] 
strList = [] 
for

maximus tee · Feb 13 '11, 12:24 AM

the code seems to give wrong result from what i expect.
result:
{'ROW1': '1X1 ', 'ROW2': 'XXX0', 'ROW3': '0X X', 'ROW4': '1XX0'}

but i'm expecting:
ROW1=01X1
ROW2=XXXX
ROW3=00X1
ROW4=11XX

pls advise. tq

thanks. btw, do you have any advice on a better s/w to use to debug python script. i'm only using IDLE and sometimes i get traceback error and not sure how to debug it except to that line.

here's the code:

Code:

def main():

    new_rows = {}
    values = []
           
    f=open('test.txt')
    for line in f:
        
        values.append(line.rstrip('\n')[-1])

thanks. i installed matplotlib, numpy, scipy and when running this code there was error:

Code:

import numpy as np 
from numpy import cos 
from scipy import * 
from pylab import plot, show, ylim, yticks 
from matplotlib import * 
from pprint import pprint 
 
n1 = 1.0 
n2 = 1.5 
 
#alpha, beta, intensity 
data = np.array([ 
    [10,    22,     4.3],

...

thanks for your advice. can you pls elaborate a bit on the purpose of cnt and how the for loop works?
i also added and else statement:

Code:

   if "-1" in dd[key]: 
        print "Line number %s failed at column %s" % (key, dd[key].index("-1")+1)
    else:
        print "All lane PASS"

However, this code reads each line and if it can't find -1, it'll print All lane PASS....

maximus tee · Jan 9 '11, 12:31 AM

the code i had written so far didn't work in cases like when there are more than one Lane having -1. any advice on how to edit the code so that it will display all lanes fail when there is -1 value. thanks.
