does the order in which the modules are placed in a file matters ?

The order of the import statements is the order the modules will get
loaded up. As a general rule this won't matter; when it comes to
standard library modules, you can generally assume that you can put
them in any order without it making any difference. It's common to
order them in some aesthetically-pleasing way (maybe alphabetical
order, or maybe sort them by the length of the name - whatever you
like).

There is a broad convention that standard library modules get imported
first, and modules that are part of the current project get imported
afterwards. But even that doesn't usually matter very much.
