Detect the Python version at run time

Sometimes, if the currently running Python engine is lower than the supported version, we may not want to execute our program. To do this, you can use the following code snippet. It also prints the version of Python currently in use in a readable format.

Import sys#Detect the Python version currently in use.if not hasattr (sys, "hexversion") or sys.hexversion! = 50660080: print ("Sorry, you aren't running on Python 3.5\ n") print ("Please upgrade to 3.5.\ n") sys.exit (1) # Print Python version in a readable format.print ("Current Python version:", sys.version)

Alternatively, you can replace sys. Hexversioncodes = 50660080 with sys.version_info > = (3,5) in the above code. This is the advice of an informed reader.
