Understanding the Enumerate Function in Python The enumerate function in Python is a built-in function that is useful when you want to have a counter along with the values while iterating over some kind of sequence such as a list or a string. When using enumerate, it returns an iterable, ...
Python decorated_func=decorator(decorated_func) Here’s an example of how to build a decorator function to add new functionality to an existing function: Python >>>defadd_messages(func):...def_add_messages():...print("This is my first decorator")...func()...print("Bye!")...return_...
Here's a fun project attempting to explain what exactly is happening under the hood for some counter-intuitive snippets and lesser-known features in Python.While some of the examples you see below may not be WTFs in the truest sense, but they'll reveal some of the interesting parts of ...
Python tends to try to abstract away implementation details like memory addresses from its users. Python often focuses on usability instead of speed. As a result, pointers in Python don’t really make sense. Not to fear though, Python does, by default, give you some of the benefits of usin...
Python 2.7 adds a dictConfig() function that uses a dictionary to configure logging. There are many ways to produce a dictionary from different sources: construct one with code; parse a file containing JSON; or use a YAML parsing library if one is installed. For more information see Configura...

Call variable outside function Calling 'Get-Counter' remotely throws error 'Unable to connect to the specified computer or the computer is offline'...
In seeing the various solutions being added it doesn't seem worth the effort. Also, Python can make quick work of the 'heavy lifting' portion of things in generating the permutations: importitertoolslist(itertools.permutations([1,2,3,4],3)) ...
The Setup The problem is simple. Given a 'cost matrix', assign tasks to workers to minimize total cost needed to complete the tasks. Workers may not perform more than 1 task. Assignment p... Really Interesting Problem!! My approach is similar to yours - generate all the permutations...
'Input string was not in a correct format' when linking a view 'object' does not contain a definition for 'id' 'System.Array' does not contain a definition for 'FirstOrDefault' 'System.Char' does not contain a property with the name 'ID'. 'System.Data.DataException' occurred in Entity...
The Pythonenumerate()function takes a data collection and returns an enumerate object. The enumerate object contains a counter as a key for each item the object contains. Theenumerate()function does so by assigning each item a count. This count corresponds to the number of iterations the functio...
