I am getting an error when I want to run a python script:
The error is following one:

I have already tried to install latexmk, But didn't succeed.
Can you help me about the detailed instruction of installation latexmk. I have already googled much. And for copyright thats not even my code. Its a code from stanford acm to make their own. Now I want to use to make my own.
Make sure that latexmk is accessible from your command line. You can check this by typing latexmk -version from your command line. If it is not accessible from command line then you need to add the latexmk path to environment variable.
If latexmk is not installed follow this link to properly install the latexmk.
I think following these steps might fix your problem.

I need to create a simplified version of grep in python which will print a line when a keyword is used such as using this command "python mygrep.py duck animals.txt" and getting the output, "The duck goes quack". I have a file where it contains different outputs but I'm not sure how to get it to print the line that contains the "keyword" such as the line with "duck" in it. Im suppose to only use "import sys" and not "re" since its suppose to be a simple version.
import sys
def main():
if len(sys.argv) != 3:
exit('Please pass 2 arguments.')
search_text = sys.argv[1]
filename = sys.argv[2]
with open("animals.txt", 'r') as f:
text = f.read()
for line in text:
print(line)
if __name__ == '__main__':
main()
The operator 'in' should be sufficient.
for line in text:
if search_text in line:
print(line)
Here is a an implementation of grep in python with after/before feature:
def _fetch_logs(self, data, log_file, max_result_size, current_result_size):
after = data.get("after", 0)
before = data.get("before", 0)
exceeded_max = False
result = []
before_counter = 0
frame = []
found = False
for line in log_file:
frame.append(line)
match_patterns = all(self._search_in(data, pattern, line) for pattern in data["patterns"])
if match_patterns:
before_counter = len(frame)
found = True
if not found and len(frame) > before:
frame.pop(0)
if found and len(frame) >= before_counter + after:
found = False
before_counter = 0
result += frame
frame = []
if current_result_size + len(result) >= max_result_size:
exceeded_max = True
break
if found:
result += frame
return exceeded_max, result
I'm trying to update 'alternatives' module for Ansible.
The default module can be found here : https://github.com/ansible/ansible-modules-extras/blob/devel/system/alternatives.py
I'm trying to add the remove arg for update-alternatives command.
My updated code is the following :
DEFAULT_LINK_PRIORITY = 50
def main():
module = AnsibleModule(
argument_spec = dict(
name = dict(required=True),
path = dict(required=True),
link = dict(required=False),
### Mode Added by isador999 ###
mode = dict(required=False),
)
)
params = module.params
name = params['name']
path = params['path']
link = params['link']
### Mode Added by isador999 ###
mode = params['mode']
UPDATE_ALTERNATIVES = module.get_bin_path('update-alternatives',True)
current_path = None
all_alternatives = []
(rc, query_output, query_error) = module.run_command(
[UPDATE_ALTERNATIVES, '--query', name]
)
if rc == 0:
for line in query_output.splitlines():
split_line = line.split(':')
if len(split_line) == 2:
key = split_line[0]
value = split_line[1].strip()
if key == 'Value':
current_path = value
elif key == 'Alternative':
all_alternatives.append(value)
elif key == 'Link' and not link:
link = value
if not mode or mode == "install":
if current_path != path:
try:
# install the requested path if necessary
if path not in all_alternatives:
module.run_command(
[UPDATE_ALTERNATIVES, '--install', link, name, path, str(DEFAULT_LINK_PRIORITY)],
check_rc=True
)
# select the requested path
module.run_command(
[UPDATE_ALTERNATIVES, '--set', name, path],
check_rc=True
)
module.exit_json(changed=True)
except subprocess.CalledProcessError, cpe:
module.fail_json(msg=str(dir(cpe)))
else:
module.exit_json(changed=False)
elif mode == "remove":
if current_path == path:
module.run_command(
[UPDATE_ALTERNATIVES, '--remove', name, path],
check_rc=True
from ansible.module_utils.basic import *
main()
When I use this new module, with install or remove mode, Ansible returns to me :
failed: [HOST] => {"failed": true, "parsed": false}
invalid output was:
* keychain 2.7.1 ~ http://www.funtoo.org
* Found existing ssh-agent: 2352
* Known ssh key: /path/id_rsa
FATAL: all hosts have already failed -- aborting
With remove mode, the script seems to be working, my Java links are correctly deleted, but I don't understand what Ansible is searching to have no error ...
Have you any idea ?
If your code above is copy-pasted as-is, then one problem is that you are importing from ansible.module_utils.basic after the main() function.
main() needs the definition of AnsibleModule to be available when parsed. You can see the imports happening at the very top of the original file, in comparison.

I have config file:
$ cat ../secure/test.property
#<TITLE>Connection setting
#MAIN DEV
jdbc.main.url=
jdbc.main.username=
jdbc.main.password=
#<TITLE>Mail settings
mail.smtp.host=127.0.0.1
mail.smtp.port=25
mail.smtp.on=false
email.subject.prefix=[DEV]
#<TITLE>Batch size for package processing
exposureImportService.batchSize=10
exposureImportService.waitTimeInSecs=10
ImportService.batchSize=400
ImportService.waitTimeInSecs=10
#<TITLE>Other settings
usePrecalculatedAggregation=true
###################### Datasource wrappers, which allow to log additional information
bean.datasource.query_log_wrapper=mainDataSourceWrapper
bean.gpc_datasource.query_log_wrapper=gpcDataSourceWrapper
time.to.keep.domain=7*12
time.to.keep.uncompress=1
#oracle max batch size
dao.batch.size.max=30
And function, which return line "#<TITLE>Other settings" (for example), to select "config section".
Next, need to print all lines between selected "section", and next line, startwith #<TITLE>.
How it can be realized?
P.S.
def select_section(property_file):
while True:
with open(os.path.join(CONF_DIR, property_file), 'r+') as file:
text = file.readlines()
list = []
print()
for i in text:
if '<TITLE>' in i:
line = i.lstrip('#<TITLE>').rstrip('\n')
list.append(line)
print((list.index(line)), line)
res_section = int(raw_input('\nPlease, select section to edit: '))
print('You selected: %s' % list[res_section])
if answer('Is it OK? '):
return(list[res_section])
break
And it's work like:
...
0 Connection setting
1 Mail settings
2 Batch size for package processing
3 Other settings
Please, select section to edit:
...
And expected output, if select Connection setting:
...
0 jdbc.main.url
1 jdbc.main.username
2 jdbc.main.password
Please, select line to edit:
...
If I understand the problem correctly, here's a solution that assembles the requested section as it reads the file:
def get_section(section):
marker_line = '#<TITLE>{}'.format(section)
in_section = False
section_lines = []
with open('test.property') as f:
while True:
line = f.readline()
if not line:
break
line = line.rstrip()
if line == marker_line:
in_section = True
elif in_section and line.startswith('#<TITLE>'):
break
if in_section:
if not line or line.startswith('#'):
continue
section_lines.append(line)
return '\n'.join(['{} {}'.format(i, line)
for i, line in enumerate(section_lines)])
print get_section('Connection setting')
Output:
0 jdbc.main.url=
1 jdbc.main.username=
2 jdbc.main.password=
Perhaps this will get you started.
Here's a quick solution:
def get_section(section):
results = ''
with open('../secure/test.property') as f:
lines = [l.strip() for l in f.readlines()]
indices = [i for i in range(len(lines)) if lines[i].startswith('#<TITLE>')]
for i in xrange(len(indices)):
if lines[indices[i]] == '#<TITLE>' + section:
for j in xrange(indices[i], indices[i+1] if i < len(indices)-1 else len(lines) - 1):
results += lines[j] + '\n'
break
return results
You can use it like:
print get_section('Connection setting')
Not very elegant but it works!

I am using Ubuntu 12.04 desktop version
The significant line of the error message is
File "/usr/lib/python2.7/codecs.py", line 881, in open
file = __builtin__.open(filename, mode, buffering)
IOError: [Errno 2] No such file or directory: '/usr/local/lib/python2.7/dist-packages/indicstemmer-0.1-py2.7.egg/indicstemmer/stemmer_ml.rules'
This implies that the indicstemmer modules had not been installed properly because the required file stemmer_ml.rules could not be found.
check that you do not need to set up defaults before you call gstem() and that the permissions in the python library allow you to get to the rules. Other than that the library package my need to be reinstalled. I have noticed that if different versions of python exist, sometimes packages get installed in the wrong version. However, I doubt it in this case because it got all the way to the rules file before crashing.
I am (attempting) to write a program that searches through a hex file for instances of a hex string between two values, eg. Between D4135B and D414AC, incrementing between the first value until the second is reached- D4135B, D4135C, D4135D etc etc.
I have managed to get it to increment etc, but it’s the search part I am having trouble with.
This is the code I have so far, it's been cobbled together from other places and I need to make it somehow output all search hits into the output file (file_out)
I have exceeded the limit of my Python understanding and I'm sure there's probably a much easier way of doing this. I would be very grateful for any help.

Here's a program that looks through a hex string from a file 3 bytes at a time and if the 3-byte hex string is between the given hex bounds, it writes it to another file. It makes use of generators to make getting the bytes from the hex string a little cleaner.
