如何删除特定于文件的消息？ 蟒蛇

Question

This is my CODE:

old_stdout = sys.stdout
pymol.finish_launching()
log_file=open('loops.log', "w")
sys.stdout = log_file

def myfunc(resi):
    print '%s' % (resi)

file= '%s'%model_initial
x= pymol.cmd.load (file, 'r')

myspace = {'myfunc': myfunc}
d= pymol.cmd.iterate('(ss l)', 'myfunc(resi)', space=myspace)
print d

pymol.cmd.quit()
sys.stdout = old_stdout
log_file.close()

old_stdout = sys.stdout
pymol.finish_launching()
log_file=open('list.log', "w")
sys.stdout = log_file

infile = 'loops.log'
outfile = 'loops1.log'

try:

delete_list = [ "Adjusting settings to improve performance for Intel cards."]
    fin = open(infile)
    fout = open(outfile, "w+")
    for line in fin:
        for word in delete_list:
            line = line.replace(word, "")
        fout.write(line)
    fin.close()
    fout.close()

    outfile = infile

except:
    infile = infile


with open(INFILE) as f:
    lines = f.read().splitlines()
    lines = lines
    lines=lines[:-1]
    lines=map(int, lines)  #Convert str list to int list
    lines=lines[:-1]
    lines=map(int, lines)  #Convert str list to int list

def group_runs(li,tolerance=2):
    out = []
    last = li[0]
    for x in li:
        if x-last > tolerance:
            yield out
            out = []
        out.append(x)
        last = x
    yield out

print list(group_runs(lines))

sys.stdout = old_stdout
log_file.close()

old_stdout = sys.stdout
pymol.finish_launching()
log_file=open('list.log', "w")
sys.stdout = log_file

fhand=open('list.log')
for lines in fhand:
    print lines

for k, g in groupby(enumerate(lines), lambda (i,x):i-x):
            ranges = []
            group = map(itemgetter(1), g)
            ranges.append((group[0], group[-1]))
            print ranges

sys.stdout = old_stdout
log_file.close()

the file loops.log, is a file with many numbers (select them of model initial, and the function principal of this CODE is group them for example:

1

2

3

4

8

9

11

15

group them:

(1,4)

(8,9)

(11, 11)

(15, 15)

This CODE works, but, when file have many many numbers, I have this message :

Traceback (most recent call last):
  File "./automaticvF.py", line 232, in <module>
    lines=map(int, lines)  #Convert str list to int list
ValueError: invalid literal for int() with base 10: 'Adjusting settings to improve performance for Intel cards.

and the log is white. I Think that is more easy remove the message of my file loops.log, and change name of file. this only happens when have many many many numbers to group, but when I have 80 numbers for example, no problem. so What can I change in this CODe, for use the variable infile, depending if the message is or not is in the infile old?

Can somebody help me please?

Thanks

Instead of redirecting the standard output of your process to a file by changing sys.stdout, you need to write your data to the file directly. You can do it, for example, like this:

print >> log_file, '%s' % (resi)

Or like this:

log_file.write(str(resi))

This will ensure that your file will not contain random unrelated data that happens to be printed to the standard output.
