GKE cluster using gitbash tool

I have my python3.7 installed on following path on my windows - C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Python 3.7

I am trying to connect GCP GKE cluster using GitBash and when i run below gcloud command to connect GKE cluster i am getting an python not found error.

$ gcloud container clusters get-credentials appcluster --region us-east4 --project dev /c/Users/surendar/AppData/Local/Google/Cloud SDK/google-cloud-sdk/bin/gcloud: line 181: exec: python: not found

Any suggestion's please to resolve the error?

Below is the Google/Cloud SDK/google-cloud-sdk/bin/gcloud file

181 line points to below declaration which is last line of the file

exec "$CLOUDSDK_PYTHON" $CLOUDSDK_PYTHON_ARGS "${CLOUDSDK_ROOT_DIR}/lib/gcloud.py

You will need to point the environment variable CLOUDSDK_PYTHON at your Python executable (e.g. python.exe). To find the Python executable, you should be able to right-click on "Python 3.7" in the start menu and look at "Target".

In my case, the Python executable is located at C:\Users\g_r_s\AppData\Local\Programs\Python\Python37\python.exe

Using Git Bash, you can export CLOUDSDK_PYTHON

$ export CLOUDSDK_PYTHON=/c/Users/g_r_s/AppData/Local/Programs/Python/Python37/python.exe
$ gcloud version
Google Cloud SDK 344.0.0
beta 2021.06.04
bq 2.0.69
core 2021.06.04
gsutil 4.62

NOTE: You can also try installing the bundled Python when you install the SDK on Windows as well.
