Shallow Copy and Deep Copy

Copy in python

Copy in python : Shallow Copy and Deep Copy  In Python programming, many times we need to make a copy of variable(s). In orders to make copy different methods are available in the Python programming.  Let’s take the example of the integer. >>> a = 10 >>> b = 10 >>> id(a) 140730625348928 >>> id(b) 140730625348928 >>> >>> x = 257 >>> y = 257 >>> id(x) 2067355160528 >>> id(y) 2067355160432 >>> If an integer value is less than 256

Python Threading – Part 2

Python threading

Python Threading In the previous article, you have seen the threading methods. In this article, you will see daemon threads and locks. Daemon Thread: So far, we have created the non-daemon thread. What is the daemon thread? When the main thread exits, it attempts to terminate all of its daemonic child threads. Consider an example of GUI as shown below Consider, by GUI input some calculation is being performed in the background and the calculation is taking its time. If you

Python Thread – Part 1

Python Thread

Python Thread A Python thread is like a process, and may even be a process, depending on the Python thread system. In fact, Python threads are sometimes called “lightweight” processes, because threads occupy much less memory, and take less time to create than do processes. Threads allow applications to perform multiple tasks at once. Multi-threading is important in many applications. In python, threading module is used to create the threads. In order to create threads, threading modules can be used

What is Python Enumerate?

Python Enumerate

Python Enumerate : python enumerate() is basically a python built in function. During certain situations where we deal with lot of iterators we also need to keep count of iterations, in these type of situations python built in function Enumerate comes handy. It helps to add counter to the iterable and returns an enumerate object. The basic syntax :- enumerate(iterable, start=0) The enumerate() function takes two parameters namely : iterable – It is a sequence, an iterator or objects which

Python modules related to datetime

python datetime

Python datetime modules: In this article, we will see the Python datetime module. We will learn how to create current time, how to calculate the time gap and how to produce time difference?According to Python docs “The python datetime module supplies classes for manipulating dates and times in both simple and complex ways”. So,python datetime modules contains several classes. Let us discuss one by one. Python datetime Modules – The Datetime.datetime Let us discuss the useful methods of datetime.datetime class.
