In this article, we will learn about What is the Python Global Interpreter Lock (GIL).This is a lock or hindrance that resistant the availability of the Python interpreter to multiple threads simultaneously. GIL is identified as a fault/issue in Python 3.x. Or earlier as it doesn’t allow multithreading in a multi-threaded architecture.Why is it introduced?Python supports the concept of automatic garbage collection. As soon as the reference count of an object reaches zero the memory is cleaned and free for usage.>>> import sys >>> var = {} >>> print(sys.getrefcount(ar)) >>> 2 >>> v=var >>> print(sys.getrefcount(v)) >>> 3Of in this case ...

In this article, we will learn about vectorization and various techniques involved in implementation using Python 3.x. Or earlier.What is Vectorization?Vectorization is a technique to implement arrays without the use of loops. Using a function instead can help in minimizing the running time and execution time of code efficiently. Various operations are being performed over vector instead of arrays such as dot product of vectors which is also known as scalar product as it produces single output, outer products which results in square matrix of dimension equal to (length X length) of the vectors, Element wise multiplication which products the ...

In this article, we will learn about isprintable() in Python and its application.Is printable() is a built-in method used for the purpose of string handling. The isprintable() methods return “True” when all characters present in the string are of type printable or the string is empty, Otherwise, It returns a boolean value of “False”.Arguments − It doesn’t take any argument when calledList of printable characters include digits, letter, special symbols & spaces.Let’s look at this illustration to check that whether the characters of string are printable or not.Example Live Demo# checking for printable characters st= 'Tutorialspoint' print(st.isprintable()) # checking if ...

In this tutorial, we will learn how to reverse an array upto a given position. Let's see the problem statement.We have an array of integers and a number n. Our goal is to reverse the elements of the array from the 0th index to (n-1)th index. For example, Input array = [1, 2, 3, 4, 5, 6, 7, 8, 9] n = 5 Output [5, 4, 3, 2, 1, 6, 7, 8, 9]Procedure to achieve the goal. Initialize an array and a number Loop until n / 2. Swap the (i)th index and (n-i-1)th elements.Print the array you will get the result.Example## initializing array and ...

In this tutorial, we are going to write a program which removes leading zeros from the Ip address. Let's see what is exactly is. Let's say we have an IP address 255.001.040.001, then we have to convert it into 255.1.40.1. Follow the below procedure to write the program.Initialize the IP address.Split the IP address with. using the split functionConvert each part of the IP address to int which removes the leading zeros.Join all the parts by converting each piece to str.The result is our final output.Example## initializing IP address ip_address = "255.001.040.001" ## spliting using the split() functions parts = ip_address.split(".") ## ...

In this tutorial, we are going to learn how to combine two dictionaries in Python. Let's see some ways to merge two dictionaries.update() methodFirst, we will see the inbuilt method of dictionary update() to merge. The update() method returns None object and combines two dictionaries into one. Let's see the program.Example## initializing the dictionaries fruits = {"apple": 2, "orange" : 3, "tangerine": 5} dry_fruits = {"cashew": 3, "almond": 4, "pistachio": 6} ## updating the fruits dictionary fruits.update(dry_fruits) ## printing the fruits dictionary ## it contains both the key: value pairs print(fruits)If you run the above program, Output{'apple': 2, 'orange': 3, ...

This article teaches you how to write a python program to find all duplicate characters in a string. Characters that repeat themselves within a string are referred to as duplicate characters. When we refer to printing duplicate characters in a string, we mean that we shall print every character, including spaces, that appears more than once in the string in question. Input-Output Scenarios Following is the input-output scenario to find all the duplicate characters in a string − Input: TutorialsPoint Output: t, o, i As we can see, the duplicate characters in the given string "TutorialsPoint" are "t" with ...
