Hi -
I am writing now my second script ever in python and need some help with
'while'. I am reading text from a set of files and manipulating the data
somehow. I use 'while 'word' not in line' to recognize words in the
texts. Sometimes, the files are empty, so while doesn't find 'word' and
runs forever. I have two questions:
1) how do I overcome this, and make the script skip the empty files?
(should I use another command?)
2) how do I interrupt the code without closing Python? (I have ActivePython)
I do know that the strings I am searching for are within the first say
50 lines.
Thanks!
Code:
|while 'PRIMARY' not in line:
line = f.readline()[:-1]
# copy scores
while 'es' not in line:
line = f.readline()[:-1]
out_file.write(line)
out_file.write(' ')
print
out_file.write('\n')
f.close()
out_file.close()
For example, 'PRIMARY' and 'es' do not exist when the file I am reading
(f) is empty.
