If you are running a frozen python script (frozen using py2exe) from a directory and drive different from where the script is present, what is the best way to determine the path of the executing script?
Few solutions I have tried
inspect.getfile(inspect.currentframe())
Problem: Does not return the full path. It only returns the script name.
os.path.abspath( __file__ )
Problem: Doesn't work on Windows
os.path.dirname(sys.argv[0])
Problem: Returns empty string.
os.path.abspath(inspect.getsourcefile(way3))
Will not work if the drive is different from the pwd
os.path.dirname(os.path.realpath(sys.argv[0]))
Will not work if the drive is different from the pwd
Here is a minimal not-working example
D:\>path
PATH=c:\Python27\;c:\Users\abhibhat\Desktop\ToBeRemoved\spam\dist\;c:\gnuwin32\bin
D:\>cat c:\Users\abhibhat\Desktop\ToBeRemoved\spam\eggs.py
import os, inspect, sys
def way1():
return os.path.dirname(sys.argv[0])
def way2():
return inspect.getfile(inspect.currentframe())
def way3():
return os.path.dirname(os.path.realpath(sys.argv[0]))
def way4():
try:
return os.path.abspath( __file__ )
except NameError:
return "Not Found"
def way5():
return os.path.abspath(inspect.getsourcefile(way3))
if __name__ == '__main__':
print "Path to this script is",way1()
print "Path to this script is",way2()
print "Path to this script is",way3()
print "Path to this script is",way4()
print "Path to this script is",way5()
D:\>eggs
Path to this script is
Path to this script is eggs.py
Path to this script is D:\
Path to this script is Not Found

Note
@Fenikso's solution will work if the script resides on the same drive where you are executing but when its on a different drive, it will not work

Another approach which works with cxFreeze when running from another drive even using PATH:
import sys
if hasattr(sys, 'frozen'):
print(sys.executable)
else:
print(sys.argv[0])
From Python:
H:\Python\Examples\cxfreeze\pwdme.py
From command line:
D:\>h:\Python\Examples\cxfreeze\dist\pwdme.exe
h:\Python\Examples\cxfreeze\dist\pwdme.exe
Using PATH:
D:\>pwdme.exe
h:\Python\Examples\cxfreeze\dist\pwdme.exe

IMHO, code that acts differently depending from absolute paths is not a good solution. It will be probably better a relative path solution. Use dirname to know the relative directory and os.sep for cross platform compatibility.
if hasattr(sys, "frozen"):
main_dir = os.path.dirname(sys.executable)
full_real_path = os.path.realpath(sys.executable)
else:
script_dir = os.path.dirname(__file__)
main_dir = os.path.dirname(os.path.realpath(sys.argv[0]))
full_real_path = os.path.realpath(sys.argv[0])
the frozen attribute is python standard.
Take a look also at Esky : http://pypi.python.org/pypi/esky

Try this:
WD = os.path.dirname(os.path.realpath(sys.argv[0]))
That is what I use with cx_Freeze to get the directory from where the .exe is really running.
