Learn how to package your Python code for PyPI. Numpy User Guide. Enumerate() method adds a counter to an iterable and returns it in a form of enumerate object. This also examines some of the simple effects from the pygame example, arraydemo.py. Description. For contributors: Numpy developer guide. reversed Returns a reverse iterator over a sequence. for loops are traditionally used when you have a block of code which you want to repeat a fixed number of times. Python documentation Documents some Python1 tips and tricks Contents 1 How to process command line arguments 1 2 Return value of enumerate 1 3 Enumerate in reverse 2 4 Convert a string to an integer 2 5 Convert an integer to a string 2 6 Launch an external process 2 6.1 … Since you are using enumerate hence your i is actually the index of the key rather than the key itself.. For a brief introduction to the ideas behind the library, you can read the introductory notes. Documentation for Python's standard library, along with tutorials and guides, are available online. This is the documentation for Numpy and Scipy. It applies a rolling computation to sequential pairs of values in a list.
