Hello NG,
probably this is a basic question, but I'm going crazy... I am unable
to find an answer. Suppose that I have a file (that I called "Errors.txt")
which contains these lines:
MULTIPLY
'PERMX' @PERMX1 1 34 1 20 1 6 /
'PERMX' @PERMX2 1 34 21 41 1 6 /
'PERMX' @PERMX3 1 34 1 20 7 14 /
'PERMX' @PERMX4 1 34 21 41 7 14 /
'PERMX' @PERMX5 1 34 1 20 15 26 /
'PERMX' @PERMX6 1 34 21 41 15 26 /
'PERMX' @PERMX7 1 34 1 20 27 28 /
'PERMX' @PERMX8 1 34 21 41 27 28 /
'PERMX' @PERMX9 1 34 1 20 29 34 /
'PERMX' @PERMX10 1 34 21 41 29 34 /
'PERMX' @PERMX11 1 34 1 20 35 42 /
'PERMX' @PERMX12 1 34 21 41 35 42 /
'PERMX' @PERMX13 1 34 1 20 43 53 /
'PERMX' @PERMX14 1 34 21 41 43 53 /
'PERMX' @PERMX15 1 34 1 20 54 61 /
'PERMX' @PERMX16 1 34 21 41 54 61 /
/
I would like to replace all the occurrencies of the "keywords" (beginning
with the @ (AT) symbol) with some floating point value. As an example, this
is what I do:
# --- CODE BEGIN
import re
import string
# Set Some Dummy Parameter Values
parametervalues = range(1, 17)
# Open And Read The File With Keywords
fid = open("Errors.txt","rt")
onread = fid.read()
fid.close()
# Find All Keywords Starting with @ (AT)
regex = re.compile("[EMAIL PROTECTED]", re.IGNORECASE)
keywords = regex.findall(onread)
counter = 0
# Try To Replace The With Floats
for keys in keywords:
pars = parametervalues[counter]
onread = string.replace(onread, keys, str(float(pars)))
counter = counter + 1
# Write A New File With Replaced Values
fid = open("Errors_2.txt","wt")
fid.write(onread)
fid.close()
# --- CODE END
Now, I you try to run this little script, you will see that for keywords
starting from "@PERMX10", the replaced values are WRONG. I don't know why,
Python replace only the "@PERMX1" leaving out the last char of the keyword
(that are 0, 1, 2, 3, 4, 5, 6 ). These values are left in the file and I
don't get the expected result.
Does anyone have an explanation? What am I doing wrong?
Thanks to you all for your help.
Andrea.
