Stdin redirection from Python -

I have a program that can be read by the name of some_binary :

  few_languages ​​< Input   
 Where  input  is usually a file in the disk. 
 
 
 
 
  
   
  
 / Code> Usually a file containing the following content I have this in Python:  
  0 0.2 0 0.4 1 0.2 0 0.3 0 0.5 1 0.7   
 I do this in Python like this:  < Import as pre>  np # np # random binary numbers first_column = np.random.random_integers (0,1, (6,)) random number between # 0 and 1 second_column = np .random.random ( (6,))   
 How can I feed the combination of  some_binary to  first_column  and  second_column   As I  some_binary & lt;   , Cwd = None, my_input): retVal = subprocess.Popen (cmd, shell = true, stdout = subprocess.PIPE, stdin = my_input, cwd = cwd); RetVal = retVal.stdout.read (). Strip ('\ n'); Retval;   
 But I'm not sure I'm going in the right direction.   
 
 
 Yes, you are going in the right direction.  
 You can use Python  subprocess.check_output ()  function which is a feature wrapper around the  subprocess. Popen () .  Popen  needs more infrastructure  
 something like  
 when something happens  
  
 < / P> 
  
 <>  Output = Subprances Checkout ([CMD], stdin = my_input)   
 should work in your case.
