Python – Ternary operator

Programming languages derived from C usually have following syntax:

(condition) ? (expression1) : (expression2)

The Python BDFL (creator of Python, Guido van Rossum) rejected it as non-Pythonic, since it is hard to understand for people not used to C. Moreover, the colon already has many uses in Python. So, when PEP 308 was approved, Python finally received its own shortcut conditional expression:

(expression1) if (condition) else (expression2)
e.g. reuse_appliances = True if use_existing_systems == 'True' else False
