Work Step by Step
Two versions of Python are currently coexistent: Python 2 and Python 3. The programs written in Python 3 will not run in Python 2. Python 3 is a newer version, but it is not backward-compatible with Python 2. This means that if you write a program using the Python 2 syntax, it may not work with a Python 3 interpreter. Python provides a tool that automatically converts code written in Python 2 into syntax Python 3 can use.
