You can check the version of Python that is running a program, at runtime.
First you need to import the
sys module from the standard library:
Then check the content of the
This property returns the Python version as a tuple.
>>> sys.version_info sys.version_info(major=3, minor=9, micro=0, releaselevel='final', serial=0)
Python lets you compare tuples, so you can check for example if the current Python version is 3.7.0 or higher:
sys.version_info >= (3, 7)
You can add this check in a conditional then, to quit the program when a Python version is too old:
if sys.version_info < (3, 7): print('Please upgrade your Python version to 3.7.0 or higher') sys.exit()
