Read the first 7 Modules, Libraries & Debugging flashcards as text
Which statement correctly imports only the `sqrt` function from the `math` module?
Answer: from math import sqrt
The `from module import name` syntax imports a specific name directly into the current namespace.
What does `sys.argv[0]` contain when running a Python script?
Answer: The name of the script file
`sys.argv[0]` always holds the script's filename (or an empty string in interactive mode).
What is the purpose of the `__all__` list defined inside a module?
Answer: Controls what is exported when `from module import *` is used
`__all__` explicitly declares which names are exported during a wildcard import.
Which built-in function returns a list of names defined in the current namespace or a given object?
Answer: dir()
`dir()` returns a sorted list of names in the current scope or the attributes of the passed object.
In the `logging` module, which level is HIGHER in severity than WARNING?
Answer: ERROR
The logging severity order is DEBUG < INFO < WARNING < ERROR < CRITICAL.
What exception is raised when you try to import a module that does not exist?
Answer: ModuleNotFoundError
`ModuleNotFoundError` (a subclass of `ImportError`) is raised when Python cannot locate the specified module.
Which `pdb` command prints the value of a variable while debugging?
Answer: print / p
In pdb, the `p expression` command evaluates and prints the value of an expression.
