Re: Same import lines again and again
Imports are generally done at the beginning of a script, are global, and don't need to be repeated. Once a module is imported it essentially increases the library of functions and classes you can create, and you can access it anywhere within your program, which makes re-importing it purely redundant. For example:
import os
#standalone
print(os.path)
#in a function
def path():
print(os.path)
path()
#in a class
class example(object):
def __init__(self):
print(os.path)
a = example()In every instance, whether its on its own, in a function, or in a class, I can use the OS module anywhere I choose without having to import it ever again beyond at the beginning of the script. In the case of the classes, you could re-initialize the classes by going "a = example()" to create an entirely new instance of that class every time, again no imports necessary.
