“ python main.py”和“ python /home/work/main.py”运行是否不同

Question

I run a python script with "python main.py" in the shell under the main.py directory, it reports an errors and stops.But when I run the same script with full path like "python /home/work/main.py" under the same circumstance, It is blocked until I interrupt it with "Ctrl+C", a error is reported when it is interrupted.But it seems go the same and normally if no errors exist.

I don't know why, can somebody tell me ?

the errors:

^CTraceback (most recent call last):
  File "/home/work/video/fe/tvservice/main.py", line 17, in <module>
    from conf.settings import DATABASE_TV, WEB_SERVER_CONFIG, DATABASE_TV_MASTER,DATABASE_TV_LOG_MASTER, ZOOKEEPER_CONFIG
  File "/home/work/video/fe/tvservice/conf/settings.py", line 1
    hello world
              ^

settings.py hello world

If you are executing it from exactly the same directory, and you are executing exactly the same file, most should be the same. The difference that you could possibly think about is value of:

sys.argv[0]  # will be either '/home/work/main.py' or 'main.py'

Just make sure that:

• you are executing the same file,
• you are using the same virtual environment (or not using it in both cases),
• you are executing the command from the same directory,

Results for the following should be exactly the same:

# Imports, so the commands will not fail
import os
import sys

# These should be the same in both cases - print them/log/whatever and compare
os.getcwd()
sys.path
