Theory package
What is the package?
Comes in a __init__. Py folder, the package can also be imported
and may import all modules together under the package Why use packages? Package management module can help us, there is a __init__ in the package. Py, by its management module to help us how to use the package? import the package. module name from the package import module name from the package. module name import module name what happens when introduced into the package 1. When the package is introduced, will package the __init__. Py generates a name space 2 . then the __init__ performed. py, will the __init__. All py names are added to the name space 3. next will package under the names of all modules loaded into the __init__. namespace generated py 4. introduced pointing module namespace is actually __init__. namespace py generated
