python - Iteration over n values -

I want to make a walk to calculate all the possibilities of a given formula. I have to write nested walk but I can not make it correct. I am not good on algorithms: (3) <3> <3> <3> <3> for the calculation of all the probabilities (% 0-% 100), 3 static {z1, z2, z3} values, I prepared:

  for z1 in A = frange (0,1.0,0.01): one in z3 for z: in z3: calculation (z1, z2, z3)    and works properly as I expect.  
 If z is a list containing n values (n can be 2-30 in my case), Which algorithm gives you suggestions that I Can I handle it? How do I create nested arrays?   
 
  The easiest way to do  itertools Product () :  
  a = frange (0,1.0,0.01) in itertools.product for z (a, repeat = n): calculation (* Z)    If  N  would actually be  30 , this would be  100 ** 30 = 10 ** 60  Values will be repeated. Be ready to wait.

visual studio 2010 - How to reinstall MVC 2 tools for VS2010? -



    I uninstalled ASP.Net MVC 2 device for Visual Studio 2010. How can I restore it? MVC2 downloads seem to include only the VS2008 device.   Whatever I said, says that MVC 2 has been included in VS2010, but the installation of an improvement did not fix it, and MVC 2 is not listed. Add VS2010 / Select a component in the Remove screen.      You will get your VS2010ToolsMVC2.msi VS2010 DVD under WCU \ ASPNETMVC - hopefully it will do!    






Git Bash script to check whether repo has any commits? -



    I have a script on which I need to work differently if there is one, which is one or more , Commits. What is the best way to do this?   Something like this will appear in the proxy code.    #! / Bin / bash if [[`git log_count`] ==" 0 "]]; Then there is no commodity for this repo. # What goods ... and echo are "one or more committed!" # What are the other things?    Any ideas?      you can    git rev-parse -verify HEAD    (after :)     This is a pipeline command, and its behavior vs. "  git diff " There is very little possibility to change   I find it more pronounced  rev-parse -verify  means "is this a valid object name?"    This is your  show-ref .  You ask "Is there anything in this safe / head in the safe?"  I ask, "what current  head  exists?"   In practice, both of these are fair tests, because once you have a branch, so to achieve the  HEAD , some mock values will indicate manually lack of editing It is very diffic...
