visual studio 2010 - python script to build multiple .msbuild files -

i new in python apologise rookie mistakes :)

i need write python script sets environment visual studio, creates temporary workspace, checks out latest version tfs , runs multiple .msbuild files under single directory , saves output log file.

i came script not working:

import subprocess command = "cmd.exe /c dir c:\\"  all_logs = []  def run_cmd(command):     """run command , print output"""     print 'running: "%s"' % command     print 'working dir: %s' % os.getcwd()     print 'env params: %s' % os.environ     p = subprocess.popen(command, shell=true, stdin=subprocess.pipe, stdout=subprocess.pipe, stderr=subprocess.stdout)     out, err = p.communicate()     print 'output: %s' % out     print 'error: %s' % err     all_logs.append(out)  def set_env_params():     os.environ['path'] = os.environ['path'] + r';c:\program files (x86)\microsoft visual studio 10.0\vc'  def run_tasks():     #get variables     #set env parameters     set_env_params()     #source code checkout     #script     run_cmd('tf c:\users\username\documents\tfs /recursive')     run_cmd('msbuild.exe   c:/users/username\documents\tfs\buildscripts/msbuild/libraries.msbuild')     run_cmd('msbuild.exe   c:\users\username\documents\tfs\buildscripts/msbuild/pex.msbuild')     run_cmd('msbuild.exe   c:\users\username\documents\tfs\buildscripts/msbuild/dhsati.msbuild')     run_cmd('msbuild.exe   c:\users\username\documents\tfs\buildscripts/msbuild/dhbati.msbuild')     run_cmd('msbuild.exe   c:\users\username\documents\tfs\buildscripts/msbuild/view.msbuild')     run_cmd('msbuild.exe   c:\users\username\documents\tfs\buildscripts/msbuild/datafeed.msbuild')     run_cmd('msbuild.exe   c:\users\username\documents\tfs\buildscripts/msbuild/apps.msbuild')     run_cmd('msbuild.exe   c:\users\username\documents\tfs\buildscripts/msbuild/misc.msbuild')     run_cmd('msbuild.exe   c:\users\username\documents\tfs\buildscripts/msbuild/sdp.msbuild')     run_cmd('msbuild.exe   c:\users\username\documents\tfs\buildscripts/msbuild/unittests.msbuild')   def main():     print '### starting tasks ###'     run_tasks()     print '### finished tasks ###'   if __name__ == '__main__':     #to run if python script executed directly     main()  

the main issues have are: 1) setting env variables gor vs2010 not enough. in order cmd understand 'tf' commands need run vcvarsall.bat file.

2) if add 'start "c:\program files (x86)\microsoft visual studio 10.0\vc\vcvarsall.bat"' command, cmd opening, correct environment commands follow, in script, cannot inserted in new cmd.

i tried writing bat file, run script had same issue cmd processes.

questions:

1) there way run commands under single process?

2) best way me this?
