Checking krishnamurthy number in python

Checking krishnamurthy number in python #Krishnamurthy Number : It is a number which is equal to the sum of the factorials of all its digits. #For example : 145 = 1! + 4! + 5! = 1 + 24 + 120 = 145 a=int(input("enter any number")) g=a fact=1 sum=0 while(a>0): r=a%10 fact=1 for i in range(1,r+1): fact=fact*i sum=sum+fact a=a//10 if(sum==g): print("krishna____ number") else: print('not')

Python Tops The List of Top 10 Programming Language Of 2017

Top 10 Programming Language Of 2017 What kind of programming skills do you need to survive in the extremely ever growing competent market always remains the burning question? IEEE Spectrum research group, a publication of The Institute of Electrical and Electronics Engineers, a technical advocacy organization, has the answer for you. According to their 2017 IEEE Spectrum ranking published recently, Python claimed the top spot as it was the highly desirable coding skill by recruiting companies. It was followed closely by C, Java, and C++. The ranking was created by the Institution of Electrical and Electronics Engineers by weighting and combining 12 metrics from 10 sources. The data chosen was based on developing languages, what companies are looking for, job postings and what’s most popular in open source. The data were collected from Google Search, Twitter, GitHub, Reddit, Hacker News, Google Trends, Stack Overflow, CareerBuilder, Dice, and its own digital library. The da

Complex Problems which can be solved in a line or two using python

1.Removing duplicate elements from list or array Example: input [1,1,1,2,2,3,4,5,6,6,1] output [1, 2, 3, 4, 5, 6] we can convert the given list into set which will remove its duplicate elements and then again convert it back to the list. >>> a= [1,1,1,2,2,3,4,5,6,6,1] >>> list(set(a)) [1, 2, 3, 4, 5, 6] 2.Using filter function to solve complex problem like extracting even numbers from list or a number greater than some number. We can use the filter method to to solve above problem. The filter() method filters the given sequence with the help of a function that tests each element in the sequence to be true or not. Extracting numbers greater than another number such as 2 Example Input:[1,2,3,4] Output:[3,4] >>> n=[1,2,3,4] >>> print ( list ( filter ( lambda x : x > 2 , n ))) [3,4] Extracting even numbers from a list Example: Input: [0,1,2,3,5,8,13]
