How to save Pandas data into Excel multiple sheets?
To save Pandas DataFrames into multiple excel sheets, we can use the pd.ExcelWriter() method. Make sure you have the openpyxl package installed before using ExcelWriter().StepsCreate a two-dimensional, size-mutable, potentially heterogeneous tabular data, df1.Print the input DataFrame, df1.Create another DataFrame, df2, and print it.Use ExcelWriter() method to write the given formatted cells into an Excel sheet.Exampleimport pandas as pd df1 = pd.DataFrame( [[5, 2], [4, 1]], index=["One", "Two"], columns=["Rank", "Subjects"] ) df2 = pd.DataFrame( [[15, 21], [41, 11]], index=["One", "Two"], columns=["Rank", ...
Read MoreHow to write text in subscript in the axis labels and the legend using Matplotlib?
To write text in subscript in the axis labels and the legend, we can take the following steps −Create x and y data points using NumPy.Plot x and y data points with a super subscript texts label.Use xlabel and ylabel with subscripts in the text.Use the legend() method to place a legend in the plot.Adjust the padding between and around subplots.To display the figure, use the show() method.Exampleimport numpy as np import matplotlib.pyplot as plt plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True x = np.linspace(1, 10, 1000) y = np.exp(x) plt.plot(x, y, label=r'$e^x$', c="red", lw=2) plt.xlabel("$X_{axis}$") plt.ylabel("$Y_{axis}$") plt.legend(loc='upper left') plt.show()Output
Read MoreHow to resize an Entry Box by height in Tkinter?
An Entry widget in a Tkinter application supports singleline user inputs. You can configure the size of an Entry widget such as its width using the width property. However, tkinter has no height property to set the height of an Entry widget. To set the height, you can use the font('font_name', font-size) property. The font size of the text in an Entry widget always works as a height of the Entry widget.ExampleLet us take an example to understand this more clearly. Follow the steps given below −Import the required librariesCreate an Entry widget, set its width and height by specifying ...
Read MoreRandom Replacement of words using Python
Introduction to Random Replacement of Word In this article, we are going to learn about the random replacement of words. Random word replacement means that we will randomly select a word from the input text and replace that word with the word that we will select randomly from the list of strings. This process helps us introduce variation and generates different text versions. As we know python is a free, open-source programming language, which provides us with a range of tools and functionalities by the help of which we could perform random replacement of words. We are going to use ...
Read MorePython - Product and Inter Summation dictionary values
Introduction This article will help us to understand the dictionary and how we can get its values with the help of its key. In Python, the dictionary is a collection of key, value pairs. We are going to learn about calculating the product and summation of dictionary values using the values() method. To calculate the sum of dictionary values we are going to use a loop to traverse through each value present in the dictionary and add it to the result variable(initially which is 0) and keep on updating it with each value until all the values of the dictionary ...
Read MoreHow to Produce K evenly spaced float values in Python?
Introduction to Produce K evenly spaced float values in Python This article will focus on how to produce k evenly spaced float value using Python. As we know python is an open-source, flexible programming language that offers a huge number of functions for manipulating data and analysis. In this article, we will understand how to produce k evenly spaced float values in Python, where k would be the number of values that has to be printed. The method to find evenly-spaced float values is used in many real-life applications such as in scientific computing, data visualization, and in mathematical operations. ...
Read MoreHow to Print the Last Word in a sentence using Python?
Introduction This article will be focusing mainly on how to print the last word in a sentence using Python. We will be using a simple technique to achieve the task. Python is an open-source, flexible, powerful programming language that provides us with various modules and functionalities that helps us to manipulate strings easily. For printing the last word in a sentence, we will use Python’s built-in string functions. Our approach is that we will first break down the input sentence i.e., given input string into a list of words and access the last element of the list to obtain the ...
Read MoreHow to Print a Heart Pattern Using Python?
Introduction In this article, we are going to focus on how to print a heart pattern using Python. We will look into the syntax of the function that is going to be used in the code. We will also learn about the method definition and the arguments that the method will take and their purpose. As we all know python is an open-source versatile programming language that provides a huge number of modules and functionalities to accomplish our task. with Python's simplicity and readability, we can transform our computer screen into a canvas with just a few lines of code. ...
Read MoreStatistical Simulation in Python
Statistical simulation is the task of making use of computer based methods in order to generate random samples from a probability distribution so that we can model and analyse complex systems which exhibit random behaviour. In this article we are going to see how to make use of this powerful tool in Python to make predictions, generate insights as well as evaluate the performance of statistical algorithms. There are different types of statistical simulations, which are as follows: Monte Carlo simulations − Generation of random samples from a probability distribution in order to estimate the expected value of a ...
Read MoreNetwork Analysis in Python
A network is a collection of nodes and edges that represent the relationships or connections between those nodes. The nodes can represent various entities, such as individuals, organizations, genes, or websites, while the edges represent the connections or interactions between them. Network analysis is the study of the relationships between these entities are node represented as a network. In this article, we are going to see how to implement network analysis using python. It involves the use of many mathematical, statistical and computational techniques. Network analysis can provide insights into the behaviour of complex systems and help to make ...
