This blocking function will start a process and wait until the new process exits before moving on. The documentation recommends using run() for all cases that it can handle. For edge cases where you need more control, the Popen class can be used. Popen is the underlying class for the ...
In the previous sections, you have seen a lot of examples already of how you can call a function. Calling a function means that you execute the function that you have defined - either directly from the Python prompt or through another function (as you will see in the section “Nested Func...
