Problem 48 Project Euler solution with Python

Self powers

The series, 11 + 22 + 33 + ... + 1010 = 10405071317.
Find the last ten digits of the series, 11 + 22 + 33 + ... + 10001000.


A very simple program. I think there is no need for explaining anything in this program.

Program

# http://radiusofcircle.blogspot.com
import time
# time at the start of program execution
start = time.time()
# solution variable
sol = 0
# for loop to loop till 1000
for i in xrange(1, 1001):
sol += i**i
# printing the last 10 digits
print str(sol)[-10:]
# time at the end of program execution
end = time.time()
# printing the total time for execution
print end - start

Summary

I don't have any words to talk about this problem. A direct and simple solution. I think even a very beginner of python can write a very fast and optimized solution. As you can see the program executes in less time and I am satisfied with the solution. One can think in mathematical point of view to improve the performance.

 As always you can comment in the comment box below, if you have any doubt or didn't understand anything. I will be glad to help you.

 Please do comment in the comment box, if you have found any typo or have a better program or different program. Please do comment if you have any suggestion. I will be very happy to view each of them.

 You can also contact me.

 Thank you. Have a nice day😃!

Add/Embed SVG to Blogger website

If not please see S calable V ec tor G raphics Recently when I tried to embed a SVG image for a post on pygal, I tried uploading the SVG file and blogger Image uploader came up with an error, because of which I had to find some other way.  SVG File upload Error in Blogger  I started sea rc hing Google " Embed SVG in Blogger " . I found blogorrhea , w h ich gave some i nformatio n on add ing SVG directly as a markup , which worked , but I faced another problem using this . Also th is guy has used lot of Javascript which was confusin g for me, being new to using SVG.   So I first t houg ht of learning on h ow to embed SVG in HTML and t his on e worked out. Actually we can embed SVG in HTML i n following ways: Using Object tag Using Iframe tag Using embed...

Problem 60 Project Euler Solution with python

Prime pair sets The primes 3, 7, 109, and 673, are quite remarkable. By taking any two primes and concatenating them in any order the result will always be prime. For example, taking 7 and 109, both 7109 and 1097 are prime. The sum of these four primes, 792, represents the lowest sum for a set of four primes with this property. Find the lowest sum for a set of five primes for which any two primes concatenate to produce another prime. This problem is j u st a brute force problem. If you have come here because you don't know the limit upto which you will h ave to gener ate the prime numbers t hen go ahe ad and t r y with 10,000 . When I first start ed solving the problem I chose 1 million(beca use most of the problem s on project E uler have this limit ), but it took very long for the computer to fin d the solution. After searching on the internet then I found many people choosing 10, 000 so I have changed my in put f rom 1 million to 10000 and the output was f ast. He...

Making a quiz web app with python and flask

Edit : When you are creating a web app with h tml templates, then y ou will have to sa ve the html file in templates folder in the Current Wor ki ng Directory( CWD). If you save the file in the C W D directl y you will get a TemplateNotFound error. Thank you Udhay for pointing it out.   In this post we will create a quiz website using python . I will be using the flask framework . After reading this tutorial you will learn form submission , flask templates , python code in flask templates , shuffling the questions and options with the random module and few others.  Please note that this tutorial is not big as it seems to be. Some of the code has been rewritten to maintain consistency and also font size is somewhat big so that your eyes won't get stressed reading this tutorial. Also the content has not occupied the full width of the page. In this tutorial I am assuming that you are having a very basic understanding of the flask framework . Please refer the documenta...
