Unable to get a pdf file from executing pyreport

Question

We have been asked to generate a report using pyreport, but anytime I run the command pyreport last.py in command prompt I get these feedback:

Traceback (most recent call last):
   File "C:\Python27\Scripts\pyreport-script.py", line 9, in <module>
     load_entry_point('pyreport==0.3.4c', 'console_scripts', 'pyreport')()
   File "C:\Python27\lib\site-packages\pyreport-0.3.4c-py2.7.egg\pyreport\pyreport.py", line 52, in commandline_call
     pyfile = open(args[0],"r")
IOError: [Errno 2] No such file or directory: 'last.py'

Please help me solve this problem. i also already have latex installed on my computer does it have anything to do with this problem?
