Python: run a python script inside the git-bash environment

Question

I having problems to run a python script inside the git-bash environment. My app is running (for now) from an exe-container (py2exe) and it should just execute another python script, but inside the git-bash environment.

The app and the git-bash.exe are inside the same directory (the entire portable version of git is extracted into this folder). The second script I want to run is in a subfolder named scripts.

Here the python file, which will be compiled as the self executable: import os

try:
    root = os.path.dirname(__file__)
except: 
    root = os.path.dirname(sys.argv[0])

git       = os.path.join(root,"git-bash.exe")
gitScript = os.path.join(root,"scripts","git_deploy.py")

I was trying different variations, but without any success:

# 1st try:
subprocess.Popen(["python", gitScript], executable=git)

# 2nd try:
subprocess.Popen(["python %s"%gitScript], shell=True, executable=git)

# 3rd try:
subprocess.Popen(["-c", "python", gitScript], executable=git)

# 4th try:
subprocess.Popen([git, "python", gitScript])

# 5th try:
subprocess.Popen([git, "-c", "python", gitScript])

Any idea what I doing wrong here?

Thanks

I've given the following a quick test and it seems to work. A couple of things:

You have to ensure C:\Program Files (x86)\Git\bin is in your System's PATH environment variable
You'll have to fix the paths yourself to match your system's configuration.
Any slashes in paths need to be escape (i.e. "double slashes").
The path to your git_deploy.py will need to be wrapped in double quotes, which means you'll have to escape those quotes with a double back-slash: \\"<path_to_git_deploy.py>\\"

The example code:

import os, shlex, subprocess
from subprocess import Popen, PIPE, STDOUT

gitScript = 'C:\\Users\\MYUSERNAME\\Downloads\\scripts\\git_deploy.py'
command = '"C:\\Program Files (x86)\\Git\\bin\\sh.exe" --login -i -c "python \\"' + gitScript + '\\""'
command_args = shlex.split(command)
process = Popen(command_args, stdout=PIPE, stderr=STDOUT)
output, err = process.communicate()
print output

THX, but I use a portable version of Git, so I setup the environment for the system variables on the fly.. works fine
