• To use python from windows command line, you need to set environmental variable PATH: settingEnvironmentVariableWindows

  • To directly install library packages to python. Extract the folder pyserial-2.5 from the downloaded tarball to C:\Python27\Lib\site-packages. Then, install from the directory: C:\Python27\Lib\site-packages\pyserial-2.5 by running python setup.py install

  • Input output file handling from command line python. If you are the only one to use the program and don’t need any defensive programming use this technique.

#command line: python posCreate.py spheres.text output.pos
import sys

#for arg in sys.argv:    #shows input arguments
#    print arg

print 'Input file:'+ sys.argv[1]
print 'Output file:'+ sys.argv[2]

inputFile = open(sys.argv[1], "r+") # files are in your python environment to play with
outputFile = open(sys.argv[2], "r+")
