As yet, you have not needed to group statements, but that will change in the next tutorial with the introduction of control structures. Until then, be aware that leading whitespace matters.Conclusion This tutor

Two ways to do this are with ARGV and optparse. The ARGV structure is a list containing the name of the program and all the arguments that were passed to the application on the command line. This uses the sys module. The other option is the optparse module. This gives more options for...
This course introduces the dictionary data structure and user-defined functions. You’ll learn about local and global variables, optional and keyword parameter-passing, named functions and lambda expressions. You’ll also learn about Python’s sorted function and how to control the order in which ...

The overall structure of your program is the same, but the highlighted lines indicate the changes you needed to make. On line 20, you created an instance of the ThreadPoolExecutor to manage the threads for you. In this case, you explicitly requested five workers or threads. Note: How do ...

NumPy is a scientific computing library for Python. It offershigh-level mathematical functions and a multi-dimensional structure (know asndarray) for manipulating large data sets. While NumPy on its own offers limited functions for data analysis,many other libraries that are key to analysis—such ...
