# This is a helper script for detecting Python executables in the PATH. It is intended to be used for determining
|
||
|
|
# which Python should be used with idf_tools.py for installing tools and exporting environment variables.

|

|
|
# 1. The script will set variable ESP_PYTHON to "python" if it is of version 3.
|
||
|
|
# 2. Otherwise, "python3" will be exported if it exists.
|
||
|
|
# 3. The script will fall-back to "python" as the last resort and fail if it doesn't exist.
