Python Internet String Preparation
To identify different things in the internet, it is necessary to compare different identification for equality. The comparison procedure depends on the application domain. For an example, some things are case-insensitive etc. To check these kind of information stringprep is used. The RFC 3454 defines the procedure to prepare the Unicode strings before transmitting through the wire. After going through the preparation procedure, they have a certain normalized form. The RFC defines a set of tables; these tables can be combined into profiles. For an example there is a profile of stringprep is nameprep. In the nameprep, there are internationalized ...
Read MorePython program to find Intersection of two lists?
Intersection operation means, we have to take all the common elements from List1 and List 2 and all the elements store in another third list. List1::[1, 2, 3] List2::[2, 3, 6] List3::[2, 3] Algorithm Step 1: input lists. Step 2: first traverse all the elements in the first list and check with the elements in the second list. Step 3: if the elements are matched then store in third list. Example code #Intersection of two lists def intertwolist(A, B): C = [i for i in A if i in B] ...
Read MoreSecond most repeated word in a sequence in Python?
The string is given, our task is to find out the second repeated word. Here we Counter(iterator) for creating dictionary which contains word as key and its frequency as value. Algorithm Step 1: Create user define list. Step 2: Then convert list into a dictionary. Step 2: Next get the values and sort them in descending order. Step 3: Then the second element is the second largest value. Step 4: Next again traverse whole dictionary and display key whose value is equal to second largest element. Example code # To print Second most repeated word in a ...
Read MorePython Completion function for GNU readline
Unix readline module has tab completion mechanism. To get these features, we have to use rlcompleter module. It can be used in python’s interactive mode. To use this module, we should import it using − import rlcompleter There is a class called Completer class − Method Completer.complete(text, state) This method is used to return the tab completion output. If there is a ‘.’ in the text, then it will try to get all related members of that command. When there is no dot ‘.’ it will just complete the text. Example Code import rlcompleter import sys ...
Read MorePrint powers using Anonymous Function in Python?
Here we used anonymous (lambda) function inside the map() built-in function. In Python, anonymous function is defined without name, its defined using lambda keyword. Algorithm Step 1: input n Step 2: input p Step 3: use anonymous function. Step 4: display result. Example Code # To display the powers of any number using anonymous function n = int(input("Enter how many terms want to display??")) p = int(input("Enter the number want to calculate power ::")) # use anonymous function cal = list(map(lambda i: p ** i, range(n))) # display the result print("The total terms is ::>", ...
Read MoreFind average of a list in python?
Python provides sum function for calculating n number of element. Here we use this function and then calculate average. Algorithm Step 1: input “size of the list” Step 2: input “Element” Step 3: using sum function calculate summation of all numbers. Step 4: calculate average. Example code # Average of a list A=list() n=int(input("Enter the size of the List ::")) print("Enter the number ::") for i in range(int(n)): k=int(input("")) A.append(int(k)) sm=sum(A) avg=sm/n print("SUM = ",sm) print("AVERAGE = ",avg) Output Enter the size of the List ::5 Enter the number:: 10 20 30 40 50 SUM = 150 AVERAGE = 30.0
Read MorePython Program to crawl a web page and get most frequent words
Our task is to crawl a web page and count the frequency of the word. And ultimately retrieving most frequent words. First we are using request and beautiful soup module and with the help of these module creating web-crawler and extract data from web page and store in a list. Example code import requests from bs4 import BeautifulSoup import operator from collections import Counter def my_start(url): my_wordlist = [] my_source_code = requests.get(url).text my_soup = BeautifulSoup(my_source_code, 'html.parser') for each_text in my_soup.findAll('div', {'class':'entry-content'}): ...
Read MorePython program to create a sorted merged list of two unsorted list
Here two user input list is given, the elements of two lists are unsorted. Our task is to merged these two unsorted array and after that sort the list. Example Input: A [] = {100, 50, 150} B [] = {200, 30, 20} Output: Merge List:{20, 30, 50, 100, 150, 200} Algorithm Step 1: first we create two user input list. Step 2: Final merge list size is (size of the first list + the size of the second list). Step 3: then sort two list using sort() method. Step ...
Read MorePython Program to Cyclic Redundancy Check
For detecting errors in digital data CRC is used, this is a good technique in detecting the transmission errors. In this technique mainly binary division is applied. In these technique, cyclic redundancy check bits are present which is a sequence of redundant bits, these bits are appended to the end of data unit so that the resulting data unit becomes exactly divisible by a second which is predetermined binary number. At the destination side, the incoming data is divided by the same number, if there is no remainder then assumed that data is correct and it’s ready to accept. A ...
Read MoreC++11 features in Visual Studio 2015
C++11 is a version of standard C++ language. It was approved by International Organization for Standardization (ISO) on 12 August 2011 then C++14 and C++17. C++11 makes several additions to the core language. Visual C++ implements the vast majority of features in C++11. Some of the following C++11 features in Visual Studio 2015 − nullptr − In the previous nullptr, zero used to be the value and it had a drawback ofimplicit conversion to integral value. The null pointer literal is represented by std::nullptr_t. In this nullptr, no implicit conversion exists. Lambdas − The lambda expression allows to ...
