Python's "in" and "not in" Operators: Check for Membership
The first call to is_member() returns True because the target value, 5, is a member of the list at hand, [2, 3, 5, 9, 7].The second call to the function returns False because 8 isn't present in the input list of values.. Membership tests like the ones above are so common and useful in programming that Python has dedicated operators to perform these types of checks.
operator — Standard operators as functions
In-place Operators¶. Many operations have an "in-place" version. Listed below are functions providing a more primitive access to in-place operators than the usual syntax does; for example, the statement x += y is equivalent to x = operator.iadd(x, y).Another way to put it is to say that z = operator.iadd(x, y) is equivalent to the compound statement z = …
What's New In Python 3.8 — Python 3.12.1 documentation
To embed Python into an application, a new --embed option must be passed to python3-config --libs --embed to get -lpython3.8 (link the application to libpython). To support both 3.8 and older, try python3-config --libs --embed first and fallback to python3-config --libs (without --embed ) if the previous command fails.

Using Exponents in Python | Python Central
To raise an imaginary number using pow (), you simply provide the base and exponent as you would with real numbers: result = pow (1j, 2) print (result) This, again, would give the output: (-1+0j) For more intricate calculations involving both real and imaginary parts, you can proceed similarly: complex_base = 2 + 3j result = pow (complex_base ...
