How do I check which version of Python is running my script?
This information is available in the sys.version string in the sys module: >>> import sys Human readable: >>> print(sys.version) # parentheses necessary in python 3. 2.5.2 (r252:60911, Jul 31 2008, 17:28:52) [GCC 4.2.3 (Ubuntu 4.2.3-2ubuntu7)] For further processing, use sys.version_info or sys.hexversion: >>> sys.version_info (2, 5, 2, 'final', 0) # or >>> sys.hexversion 34014192 To ensure a script runs with a minimal version requirement of the Python interpreter add this to your code: assert sys.version_info >= (2, 5) This compares major and minor version information. Add micro (=0, 1, etc) and even releaselevel (='alpha','final', etc) to the tuple as you like. Note however, that it is almost always better to "duck" check if a certain feature is there, and if not, workaround (or bail out). Sometimes features go away in newer releases, being replaced by others. or Use platform's python_version from the stdlib: from platform import python_version print(python_version()) # 3.9.2 https://stackoverflow.com/questions/1093322/how-do-i-check-which-version-of-python-is-running-my-script
