Question

What’s wrong in python script?

Code:

import os    
import shutil
import getpass    
os.mkdir("C:\\dtmp") 

shutil.copy("C:\\path\\to\\bb-freeze-script.py","C:\\dtmp")
os.chdir("C:\\dtmp")
shutil.copy("C:\\path\\to\\main.py","C:\\dtmp")
os.system("python bb-freeze-script.py main.py")

os.mkdir("C:\\Program Files\\Directories v0.6")
os.chdir("C:\\")
shutil.rmtree("C:\\dtmp")

print getpass.getuser()

Error:

Traceback (most recent call last):
  File "bb-freeze-script.py", line 8, in <module>

Here’s a quick walkthrough on how to read tracebacks. It’s pretty easy.

• Looking through your code, all of it is calling Python builtin modules. It’s safe to say they’re not causing the error, so the only thing left is the os.system call. Sure enough, you’re calling python through said call (why would you not just import the module you want to call?).

• The traceback confirms that the error is in the other Python you are calling:

  Traceback (most recent call last):
    File "bb-freeze-script.py", line 8, in <module>
      load_entry_point('bbfreeze==0.97.3', 'console_scripts', 'bb-freeze')()
  

• Next, read through the lines of the transcript to burrow through the call stack and find out exactly where the error occurred.

  File "C:\Python27\lib\site-packages\bbfreeze-0.97.3-py2.7-win32.egg\bbfreeze\__init__.py", line 24, in main
      f.addScript(x)
  File "C:\Python27\lib\site-packages\bbfreeze-0.97.3-py2.7-win32.egg\bbfreeze\freezer.py", line 410, in addScript
      s = self.mf.run_script(path)
  File "C:\Python27\lib\site-packages\bbfreeze-0.97.3-py2.7-win32.egg\bbfreeze\modulegraph\modulegraph.py", line 241, in run_script
      co = compile(file(pathname, READ_MODE).read()+'\n', pathname, 'exec')
  

• until you get to

  File "C:\dtmp\main.py", line 14
  IndentationError: expected an indented block
  

There you go, the error is in line 14 of main.py, where you should have had an indent but didn’t.
