Cannot access imported functions in django shell by pipeline command

[Cheng-Hung Hsueh]

It is a python script `tshi3.py` :

在此輸入代碼...

    import csv
    def li2ho2():
        print(csv)
    li2ho2()

I copied this code and pasted it in `python manage.py shell`. It works.

But I ran `python manage.py shell < tshi3.py`. Got `NameError: name 'csv' is not defined.`

Why?

Enviroment:

在此輸入代碼...

    Linux Mint 18.1
    Python 3.4.1 (default, Sep  3 2014, 08:45:22) 
    Django==1.11.4

Wild guess: Different default directory.

Try setting PYTHONPATH, or add "os.chdir('some/dir')" to top of script...

I don't know if the 'manage.py shell' command supports what you are doing. I would instead write a management command to run arbitrary code from the command line.
