Hi: Python3.6 and python3.7 After the code removes some common values “python”, we compare “3.6” and “3.7” origin_version = “3.6”, python_version=”3.7”
I'm going to change it to if [[ "$origin_version" < "$python_version" ]]; then Any question, please let me know. Thanks.

Thanks. You might want to extract the major and minor values and compare them separately then. The "<" operator in bash does a string comparison, which I'm not sure is what's wanted here?
