Are you using a UNIX based OS such as Linux? If so, add a shebang line to the very top of your script:

#!/usr/bin/python

Underneath which you would have the rest of the code (xx.py in your case) that you already have. Then run that same command at the terminal:

$ python xx.py

This should then work fine, as it is now interpreting this as Python code. However when running from the terminal this does not matter as python tells how to interpret it here. What it does allow you to do is execute it outside the terminal, i.e. executing it from a file browser.

It s not an issue related to authentication at the first step  Your import is not working  So  try writing this on first line      usr bin python   and for the time being run using   python xx py   For you here is one explanation    gt  gt  gt  abc    Hei Buddy   gt  gt  gt  print   s   abc Hei Buddy  gt  gt  gt     gt  gt  gt  print   s   xyz  Traceback  most recent call last     File   lt pyshell 6 gt    line 1  in  lt module gt      print   s   xyz NameError  name  xyz  is not defined   At first  I initialized abc variable and it works fine  On the otherhand  xyz doesn t work as it is not initialized

If you run a script directly e g     xx py and your script has no shebang such as    usr bin env python at the very top then your shell may execute it as a shell script  POSIX says      If the execl   function fails due to an error equivalent to the    ENOEXEC  error defined in the System Interfaces volume of   POSIX 1-2008  the shell shall execute a command equivalent to having a   shell invoked with the pathname resulting from the search as its first   operand  with any remaining arguments passed to the new shell  except   that the value of   0  in the new shell may be set to the command   name  If the executable file is not a text file  the shell may bypass   this command execution  In this case  it shall write an error message    and shall return an exit status of 126    Note  you may get ENOEXEC if your text file has no shebang   Without the shebang  you shell tries to run your Python script as a shell script that leads to the error  import  command not found   Also  if you run your script as python xx py then you do not need the shebang  You don t even need it to be executable   x   Your script is interpreted by python in this case    On Windows  shebang is not used unless pylauncher is installed  It is included in Python 3 3

It s about Shebang    usr bin python   This will tell which interpreter to wake up to run the code written in file

When you see  import  command not found  on the very first import  it is caused by the parser not using the character encoding matching your py file   Especially when you are not using ASCII encoding in your py file   The way to get it right is to specify the correct encoding on top of your py file to match your file character encoding      usr bin env python3   - - coding  utf-8 - - import os

I ve experienced the same problem and now I just found my solution to this issue      usr bin python  import sys import os  os system  meld   s    s      sys argv 2   sys argv 5      This is the code 1  for my case  When I tried this script I received error message like       import  command not found   I found people talks about the shebang  As you see there is the shebang in my python code above  I tried these and those trials but didn t find a good solution   I finally tried to type the shebang my self      usr bin python   and removed the copied one   And my problem solved     I copied the code from the internet 1    And I guess there had been some unseeable    unseen special characters in the original copied shebang statement   I use vim  sometimes I experience similar problems   Especially when I copied some code snippet from the internet this kind of problems happen   Web pages have some virus special characters   I doubt   -   Journeyer  PS  I copied the code in Windows 7 - host OS - into the Windows clipboard and pasted it into my vim in Ubuntu - guest OS  VM is Oracle Virtual Machine    1  http   nathanhoad net how-to-meld-for-git-diffs-in-ubuntu-hardy
