Which of these locations will Python search for packages by default?

Which of the following statements is true?

To which package manager do the statements apply? pip, conda, neither or both?

"Non-Python packages available by default"

"Tightly integrated with its own virtual environment feature"

"Built-in third-party package repositories"

"Installs new Python executable into env by default"

"Automatically installs dependencies for requested package"

"Requires you to specify package version"

What should you always do before you optimize your code's performance? (Hard to implement).

Which index varies fastest in a row-major layout, which varies fastest in a column-major layout? (Hard to implement).

Which ordering do NumPy arrays have by default? More than one answer may be correct.

Consider the following code. What does each print statement output? Could be an error. Treat all print statements independently.

x = np.zeros(5) y = np.zeros((3, 5) z = np.zeros((5, 3, 1))

print((x + y).shape)

print((x + z).shape)

print((y + z).shape)

print(y[:2, :2].shape)

print(y[:2].shape)

print((y[:2] + x[:2]).shape)

print((y[..., np.newaxis] + z).shape)

print((y.ravel() + x[0]).shape)

	Anything that is in $PYTHONPATH
	Anything in your home
	Preconfigured Site Packages
	The current working directory

	venv comes with Python
	Virtual environments always go to ~/.virtualenvs
	Each virtual env always has its own Python instance
	The activate script has to be source-d to activate the venv
	The deactivate script has to be source-d to deactivate the venv
