Phrase extraction in String using Python
Phrase extraction in Python is the process of identifying meaningful words from a text context. In this, the text is divided into sentences, phrases, words etc. and these phrases are displayed with full meaning. This process is useful in areas such as text analysis, machine learning, and supply-demand identification (information retrieval). Phrase extraction can be used in normal language processing (NLP) tasks to separate phrases from sentences. It can help to recognize words that are known as phrases and can be used for translation, summarising etc. Here we have some method to phrase extraction. Method 1 Using list slicing, enumerate(), ...
Read MoreHow to pass multiple arguments to a map function in Python?
The map function is an in−built function in Python, which applies a given function to each and every element in an iterable (list, tuple, etc.) and returns an iterator of the result in the list. We can also use multiple arguments in the map function. Syntax This syntax is used in all the following examples − map(function, argument1, argument2, .....) Method 1: Use multiple arguments with map function Example write a program to add two list elements with the help of map function. def add(a, b): return a + b # Create two lists list1 ...
Read MoreHow to Concatenate Column Values in a Pandas DataFrame?
Pandas is a powerful library for data manipulation and analysis in Python. It provides a variety of functions and tools for handling and transforming data, including the ability to concatenate column values in a Pandas DataFrame. In a Pandas DataFrame, columns represent variables or features of the data. Concatenating column values involves combining the values of two or more columns into a single column. This can be useful for creating new variables, merging data from different sources, or formatting data for analysis. To concatenate column values in a Pandas DataFrame, you can use the pd.Series.str.cat() method. This method concatenates two ...
Read MoreHow to Collapse Multiple Columns in Python Pandas?
Pandas is a popular data manipulation library in Python that is widely used for working with structured data. One of the common tasks when working with data is to clean and transform it in order to prepare it for analysis. Sometimes, the data might contain multiple columns that have similar information or are related to each other. In such cases, it might be useful to collapse these columns into a single column for easier analysis or visualization. Pandas provides several methods to collapse multiple columns into a single column. In this tutorial, we will explore these methods in detail and ...
Read MoreCircle of Squares using Python Turtle
The Circle of Squares is a fascinating geometric pattern that can be created using Python's turtle graphics library. This pattern consists of a circle of squares that are evenly spaced around its circumference, with each square rotated at an angle relative to the previous square. This creates a mesmerizing visual effect that can be customized to suit any color scheme or size. In this tutorial, we will explore how to create the Circle of Squares pattern using Python's turtle library, step by step. We will also discuss different customization options that can be applied to create unique variations of the ...
Read MorePython | Measure similarity between two sentences using cosine similarity
Introduction Natural Language Processing for finding the semantic similarity between sentences, words, or text is very common in modern use cases. There are numerous ways to calculate the similarity between texts. One such popular method is cosine similarity. It is used to find the similarity between two vectors that are non-zero in value and measures the cosine of the angle between the two vectors using dot product formula notation. Through this article let us briefly explore cosine similarity and see its implementation using Python. Cosine similarity – Finding similarity between two texts Cosine Similarity is defined as the cosine of ...

Read MoreHow to Find Factors of Number using Python?
In order to find factors of a number, we have to run a loop over all numbers from 1 to itself and see if it is divisible.Examplenum=int(input("enter a number")) factors=[] for i in range(1,num+1): if num%i==0: factors.append(i) print ("Factors of {} = {}".format(num,factors))If i is able to divide num completely, it is added in the list. Finally the list is displayed as the factors of given numberOutputenter a number75 Factors of 75 = [3, 5, 15, 25, 75]
Read MoreHow to create Python dictionary by enumerate function?
Python enumerate() function takes any iterable as argument and returns enumerate object using which the iterable can be traversed. It contains index and corresponding item in the iterable object like list, tuple, or string.Such enumerate object with index and value is then converted to a dictionary using dictionary comprehension.>>> l1=['aa','bb','cc','dd'] >>> enum=enumerate(l1) >>> enum >>> d=dict((i,j) for i,j in enum) >>> d {0: 'aa', 1: 'bb', 2: 'cc', 3: 'dd'} Learn Python with our step-by-step Python Tutorial.
