Python program to compare two Pandas series
In this program, we will declare two Pandas series and compare their elements. Before we solve the problem, we need to import the Pandas library into our local IDE. This can be done by installing Pandas on our local machine. The command for installing Pandas is −pip install pandasInputSeries1 = [2,4,6,8,10]Series2 = [1,3,5,7,9]AlgorithmStep 1: Define two Pandas series using the Series() function of Pandas library.Step 2: Compare the series using greater than, less than, and equal-to operators.Example Codeimport pandas as pd series1 = pd.Series([2,4,6,8,10]) series2 = pd.Series([1,3,5,7,9]) print("Greater Than: ",series1>series2) print("Less Than: ",series1
Read MoreHow to maximize a plt.show() window using Python?
Using plt.get_current_fig_manager() and mng.full_screen_toggle() methods, we can maximise a plot.StepsAdd a subplot to the current figure, where nrow = 1, ncols = 1 and index = 1.Create a pie chart using list [1, 2, 3] and pie() method.Return the figure manager of the current figure, using get_current_fig_manager() method. The figure manager is a container for the actual backend-depended window that displays the figure on the screen.Create an abstract base class to handle drawing/rendering operations using the full_screen_toggle() method.Use plt.show() to show the figure.Exampleimport matplotlib.pyplot as plt plt.subplot(1, 1, 1) plt.pie([1, 2, 3]) mng = plt.get_current_fig_manager() mng.full_screen_toggle() plt.show()Output
Read MoreSaving images in Python at a very high quality
To save the images in Python with very high quality, you need to follow the steps given below −Create fig and ax variables using subplots method, where default nrows and ncols are 1.Plot the lines using plot() method.We can add axes labels using ylabel() and xlabel().To get a high-quality image, we can use .eps image format.You can increase the dot per inch value, i.e., dpi.Using savefig() method, we can save the image locally.To show the figure, use plt.show().Exampleimport matplotlib.pyplot as plt fig, ax = plt.subplots() plt.plot([0, 5], [0, 5]) plt.ylabel("Y-axis ") plt.xlabel("X-axis ") image_format = 'eps' ...
Read MorePalindrome in Python: How to check a number is palindrome?
What is a palindrome?A palindrome is a string that is the same when read from left to right or from right to left. In other words, a palindrome string is the one whose reverse is equal to the original string.For example, civic, madam are palindromes.Cat is not a palindrome. Since its reverse is tac, which is not equal to the original string (cat).Write a program to find whether the input string is a palindrome or not.Method 1 - Find Reverse of the stringThe main thing required in the program is to find the reverse of the string.The reverse can be ...

Yes, Python is a scripting language.Scripting language v/s Programming languageThe first question which strikes into the mind is, what is the difference between programming and scripting language. The only difference which exists is that the scripting language does not require any compilation, it is directly interpreted.For example, the programs written in a language such as C++ are compiled before execution whereas the programs written in scripting languages such as Python or JavaScript are directly interpreted and are not compiled.Why is Python a scripting language?A scripting language is one that is interpreted. Python is an interpreted language. Python uses an interpreter ...
Read MoreHow to print pattern in Python?
Patterns in Python can be printed using nested for loops. The outer loop is used to iterate through the number of rows whereas the inner loop is used to handle the number of columns. The print statement is modified to form various patterns according to the requirement.The patterns can be star patterns, number patterns, alphabet patterns. The patterns can be of different shapes, triangle, pyramids, etc.ExampleAll these patterns can be printed with the help of for loops with modified print statements which forms these different patterns.The basic idea between the printing of these patterns is the same with slight differences.We ...
