   • What is Python's default logging formatter?

     Top Answer

     Answered Jul 18, 2024 · 91 votes

     The default format is located here which is:

     BASIC_FORMAT = "%(levelname)s:%(name)s:%(message)s" -

     The section on formatting in the python docs will tell you how you can customize it. Here is one example on how you can customize it.

     import sysimport logging-logging.basicConfig( level=logging.DEBUG, format="[%(asctime)s] %(levelname)s [%(name)s.%(funcName)s:%(lineno)d] %(message)s", datefmt="%d/%b/%Y %H:%M:%S", stream=sys.stdout)-logging.info("HEY")-

     Which results in:

     [26/May/2013 06:41:40] INFO [root.<module>:1] HEY-

   • What is Python's heapq module?

     Top Answer

     Answered Jan 08, 2019 · 113 votes

     The heapq module maintains the heap invariant, which is not the same thing as maintaining the actual list object in sorted order.

     Quoting from the heapq

     documentation:

     Heaps are binary trees for which every parent node has a value less than or equal to any of its children. This implementation uses arrays for which heap[k] <= heap[2*k+1] and heap[k] <= heap[2*k+2] for all k, counting elements from zero. For the sake of comparison, non-existing elements are considered to be infinite. The interesting property of a heap is that its smallest element is always the root, heap[0].

     This means that it is very efficient to find the smallest element (just take heap[0]), which is great for a priority queue. After that, the next 2 values will be larger (or equal) than the 1st, and the next 4 after that are going to be larger than their 'parent' node, then the next 8 are larger, etc.

     You can read more about the theory behind the datastructure in the Theory section of the documentation. You can also watch this lecture from the MIT OpenCourseWare Introduction to Algorithms course, which explains the algorithm in general terms.

     A heap can be turned back into a sorted list very efficiently:

     def heapsort(heap): return [heapq.heappop(heap) for _ in range(len(heap))]-

     by just popping the next element from the heap. Using sorted(heap) should be faster still, however, as the TimSort algorithm used by Python’s sort will take advantage of the partial ordering already present in a heap.

     You'd use a heap if you are only interested in the smallest value, or the first n smallest values, especially if you are interested in those values on an ongoing basis; adding new items and removing the smallest is very efficient indeed, more so than resorting the list each time you added a value.

   • What is the correct way of configuring Python's logging.FileHandler?

     Top Answer

     Answered Mar 01, 2012 · 6 votes

     So, apparently I can use Python expressions inside the configuration file:

     [handler_fileHandler] <snip>args=(os.path.join(sys.path[0],'echi_export.log'), 'a',)-

     This results in the logfile being created in the same directory the script resides in.

     (os.path.dirname(__file__) resolves to /usr/lib/python2.7/logging/ on my system, which is probably where the logging module resides).

   • What is the difference between Python's Module, Package and Library?

     In this article, we will see the difference between Python’s Module, Package, and Library. We will also see some examples of each to things more clear.

     What is Module in Python?

     The module is a simple Python file that contains collections of functions and global variables and with having a .py extension file. It is an executable file and to organize all the modules we have the concept called Package in Python. 

     Examples of modules:

     • Datetime
     • Regex
     • Random etc.

     Example: Save the code in a file called demo_module.py 

     Python3

     def myModule(name):    print("This is My Module : "+ name)-

     Import module named demo_module and call the myModule function inside it. 

     Python3

     import demo_module demo_module.myModule("Math")

     Output:

     This is My Module : Math

     What is Package in Python?

     The package is a simple directory having collections of modules. This directory contains Python modules and also having __init__.py file by which the interpreter interprets it as a Package. The package is simply a namespace. The package also contains sub-packages inside it. 

     Examples of Packages: 

     • Numpy 
     • Pandas

     Example:

     Student(Package)init .py Constructor...

   The logging module lets you track events when your code runs so that when the code crashes you can check the logs and identify what caused it. Log messages have a built-in hierarchy – starting from debugging, informational, warnings, error and critical messages. You can include traceback information as well.
