Implementing Photomosaics in Python
The photomosaic is a technique, where we can split our image into a grid of squares. Each square will be replaced by some other images or colors. So when we want to see the actual image from a certain distance, we can see the actual image, but if we come closer, we can see the grid of different colored blocks. In this case we are using a Python module called photomosaic. Using this module, we can easily create some photomosaics. To install it please follow this link. It will also download the scikit learn module. sudo pip3 install photomosaic ...
Read MoreHow to get synonyms/antonyms from NLTK WordNet in Python
The WordNet is a part of Python's Natural Language Toolkit. It is a large word database of English Nouns, Adjectives, Adverbs and Verbs. These are grouped into some set of cognitive synonyms, which are called synsets. To use the Wordnet, at first we have to install the NLTK module, then download the WordNet package. $ sudo pip3 install nltk $ python3 >>> import nltk >>>nltk.download('wordnet') In the wordnet, there are some groups of words, whose meaning are same. In the first example, we will see how wordnet returns meaning and other details of a word. Sometimes, if some ...
Read MoreSend mail with attachment from your Gmail account using Python
In this article, we will see how we can send email with attachments using Python. To send mail, we do not need any external library. There is a module called SMTPlib, which comes with Python. It uses SMTP (Simple Mail Transfer Protocol) to send the mail. It creates SMTP client session objects for mailing. SMTP needs valid source and destination email ids, and port numbers. The port number varies for different sites. As an example, for google the port is 587. At first we need to import the module to send mail. import smtplib Here we are also ...
Read MoreTracking bird migration using Python-3
In some Research works, Researchers uses GPS modules to track the animal behavior. They can track how they are travelling to different places in different time of a year etc. In this example we use that kind of dataset to get an idea, how Birds are moving in different places. In this dataset there are the location details from GPS module are stored. The complete dataset is in CSV form. In that file, there are different fields. The first one is Bird Id, then date_time, Latitude, longitude and speed. For this Task, we need some modules that can be used ...
Read MoreHow does “do something OR DIE()” work in Perl?
The die() function can be used to stop the script and can be used to display a message to the end user. It can be used at the right side of the OR ( || ) operator and at left side can be any expression like the eval() function. Case 1 − Using die() function with no parameter The following is the output. Now we can use $! to print the error number and a message to the user in the die() function. Case 2 − Use of $! in the die() function The following is the ...
Read MoreGenerate a graph using Dictionary in Python
The graphs can be implemented using Dictionary in Python. In the dictionary, each key will be the vertices, and as value, it holds a list of connected vertices. So the entire structure will look like Adjacency list of a graph G(V, E). We can use the basic dictionary object, but we are using default dict. It has some additional features. It has one additional writable instance variable. We are providing a text file, which contains the number of vertices, number of edges, names of vertices, and the list of edges. For undirected graph, we are providing two edges like ...
Read MoreFormatted text in Linux Terminal using Python
In this section, we will see how to print formatted texts in Linux terminal. By formatting, we can change the text color, style, and some special features. Linux terminal supports some ANSI escape sequences to control the formatting, color and other features. So we have to embed some bytes with the text. So when the terminal is trying to interpret them, those formatting will be effective. The general syntax of ANSI escape sequence is like below − \x1b[A;B;C A is the Text Formatting Style B is the Text Color or Foreground Color C is the Background ...
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 maximum of three.
Given three number a b and c, our task is that we have to find the maximum element in among in given number. Example Input: a = 2, b = 4, c = 3 Output: 4 Algorithm Step 1: input three user input number. Step2: Add three numbers to list. Step 3: Using max() function to find the greatest number max(lst). Step 4: And finally we will print maximum number. Example Code def maximum(a, b, c): list = [a, b, c] return max(list) # ...
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 ::>", ...
