Running Terminal within a Python Script -


I am trying to run a command in the terminal via a Python script. The command, which only takes three arguments, works perfectly when executed in the terminal. What is entered in the command line here: 

  gpmetis input file number offset   
 Ask  inputfile  anywhere, desktop, < Code> outputfile  is executed in the same place after  gpmetis  (it is named as  inputfile.part.numberOfSections ).  gpmetis  works only in the terminal, but for condensing purposes, I want to use it in the middle of the Python script to save time. (I can already alter the files from terminal and python and almost)  
 But this is where I get problems ... this and it gives a useful signal that how the terminal in Python To be executed, I'm still not getting  outputfile  when I run Python code It seems that the output is suppressed or the way I call the terminal is faulty.  
 I am currently saying terminal:  
  def terminal (inputfile, numberparts): osystem ("gpmetis inputfile numparts") outputfile = "inputfile.part." + NumParts comes back to outputfile   
 And I have not received any error from this, but I have not found any output files What am I missing here and if you know that you can explain it? I am trying to learn dragon, so whatever I want to screw will be greatly appreciated.  
  os  has been imported. In my mistake I am doing "back"  outputfile , but I do not see a  outputfile  on my desktop, which should be dealt with first problem (one One step in time!)  
 Note: I found that it is related, but will it help me? I'm having trouble understanding this.   
 
 
 First of all, you have  os.system < / Code>. A zero-zero return value usually indicates that an error has occurred.  
 It looks like you are trying to use the parameter in your command, in that case it should look like:  
  def terminal (inputfile, numberparts): command = 'GPTIS' + inputfile + '' + str (nampperes) OSSystem (command) outputfile = inputfile + '.part.' + Str (NumParts) Return output file   
 Finally, depending on the answer, it seems that you can be better by using the  subprocess  module You can execute only one command:  
  Subprocess subprocess import coal (['gpmetis', inputfile, strip (newpoints)])

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
