In this post we will discuss about bigram formation from a given list in python programming language. We will discuss two methods for creating bigrams. When we are dealing with text classification, sometimes we need to do certain kind of natural language processing and hence sometimes require to form bigrams of words for processing. In … Read more
Given a list of integers, write a Python program to convert a list of multiple integers into single integer. Input : [1, 2, 3] Output: 123 Input : [55, 32, 890] Output: 5532890 There are multiple approaches possible to convert the given list into a single integer. Let’s see each one by one. Approach #1 … Read more
Here we will write a program to solve quadratic equation in Python, so first lets understand how to solve a quadratic equation. The standard form of a quadratic equation is: ax 2 + bx + c = 0, where a, b and c are real numbers and a ≠ 0 The value of a, b … Read more
Given a list of strings, write a Python program to convert case of all string from lowercase/uppercase to uppercase/lowercase. Input : [‘PrO’, ‘pROG’, ‘RAMmInG’] Output: [‘pro’, ‘prog’, ‘ramming’] Input : [‘fun’, ‘Foo’, ‘BaR’] Output: [‘FUN’, ‘FOO’, ‘BAR’] Method #1 : Convert Uppercase to Lowercase using map function out = map(lambda x:x.lower(), [ ‘PrO’, ‘pROG’, ‘RAMmInG’]) … Read more
Method Resolution Order : Method Resolution Order(MRO) it denotes the way a programming language resolves a method or attribute. Python supports classes inheriting from other classes. The class being inherited is called the Parent or Superclass, while the class that inherits is called the Child or Subclass. In python, method resolution order defines the order … Read more
In this article, we’ll learn about operator overloading in Python with examples. We all know what are operators (+, -, <=). In python, operators work for built in classes, but some operator behaves differently with different types. For example ‘+’ operator can add two numbers and also can concatenate two strings. Program: Program: a = … Read more
