Comments (7) on “HackerRank Python If-Else problem solution”

bro give me explanation of this line N = int(raw_input().strip())

the line means we are going to take an string as an integer input and then strip it means remove the white space around the string and then convert it into the integer variable.

if name=='durga': print('hello durga,good evening') print('how are you') else: print('hello durga,good evening') print('Who are you') why there is error comming in else

name = "durga" if name =="durga": print("hello durga,good evening") print("How are you?") else: print("hello durga,good evening") print("Who are you?")

if __name__ == '__main__': n = int(input().strip()) if n % 3 == 0: print ('Weird') elif n%2 == 0 and 2 >= n <= 5: print ( 'Not Weird') elif n%2 == 0 and 6 >= n <= 20: print ('Weird') elif n%2 == 0 and n>20 :

print ('Not Weird')

when i take 24 it is not printing " not weird " , why?

There might be an error while submitting for 4, for this in python3

#!/bin/python3

import math import os import random import re import sys

if __name__ == '__main__': n = int(input().strip())

if n%2 != 0: print("Weird") elif n == 4: print("Not Weird") else: if n>=2 and n<=5: print("Not Weird") if n>=6 and n<=20: print("Weird") else: print("Not Weird")

nms=[] choice='yes'

while choice=='yes': n=input ('enter a name') nms.append(n) choice=input('do you want to continue?') else: print(nms) Why is the error coming in this??

Solutions to HackerRank Coding Challenges in Python

One of the best ways to absorb and retain new concepts that I have learnt about coding in Python is through documentation! As part of my journey to future-proof my data career and also to improve my proficiency in the python language, I have spent some of my free time to solve coding challenges on HackerRank . In this blog post, I shared the solutions to some of the practice challenges which I have completed and successfully passed the code in the compiler on HackerRank . Do click on Read More or the title of this blog post for the Python 3 solutions which I have created.

Arithmetic Operators

Print function, write a function, python introduction (easy) questions.

Given an integer, n , perform the following conditional actions:

• If n is odd, print Weird
• If n is even and in the inclusive range of 2 to 5 , print Not Weird
• If n is even and in the inclusive range of 6 to 20 , print Weird
• If n is even and greater than 20 , print Not Weird

Input Format: A single line containing a positive integer, n .

Constraints:

• 1 <= n <= 100

Output Format: Print Weird if the number is weird. Otherwise, print Not Weird .

The provided code stub reads two integers from STDIN, a and b . Add code to print three lines where:

• The first line contains the sum of the two numbers.
• The second line contains the difference of the two numbers (first - second).
• The third line contains the product of the two numbers.

Print the following:

Input Format: The first line contains the first integer, a . The second line contains the second integer, b .

Output Format: Print the three lines as explained above.

Sample Input 0

Sample Output 0

The provided code stub reads two integers from STDIN, a and b . Add logic to print two lines. The first line should contain the result of integer division, a//b . The second line should contain the result of float division, a/b .

No rounding or formatting is necessary.

• The result of the integer division 3//5 = 0 .
• The result of the float division is 3/5 = 0.6 .

Input Format

The first line contains the first integer, a . The second line contains the second integer, b .

Output Format

Print the two lines as described above.

The provided code stub reads and integer, n , from STDIN. For all non-negative integers i < n , print i**2 .

The list of non-negative integers that are less than n = 3 is [0,1,2] . Print the square of each number on a separate line.

Input Format: The first and only line contains the integer, n .

Constraints: 1 <= n <= 20

Output Format: Print n lines, one corresponding to each i .

The included code stub will read an integer, n , from STDIN.

Without using any string methods, try to print the following: 123 . . . n

Note that “…” represents the consecutive values in between.

Example n=5

Print the string 12345 .

Input Format: The first line contains an integer n .

Constraints: 1 <= n <= 150

Output Format: Print the list of integers from 1 through n as a string, without spaces.

Python Introduction (Medium) Questions

An extra day is added to the calendar almost every four years as February 29, and the day is called a leap day. It corrects the calendar for the fact that our planet takes approximately 365.25 days to orbit the sun. A leap year contains a leap day.

In the Gregorian calendar, three conditions are used to identify leap years:

• The year can be evenly divided by 100, it is NOT a leap year, unless:
• The year is also evenly divisible by 400. Then it is a leap year. This means that in the Gregorian calendar, the years 2000 and 2400 are leap years, while 1800, 1900, 2100, 2200, 2300 and 2500 are NOT leap years.

Given a year, determine whether it is a leap year. If it is a leap year, return the Boolean True , otherwise return False .

Note that the code stub provided reads from STDIN and passes arguments to the is_leap function. It is only necessary to complete the is_leap function.

Input Format: Read year , the year to test.

Constraints

1900 <= year <= 10 ** 5

Output Format: The function must return a Boolean value (True/False). Output is handled by the provided code stub.

Explanation 0

1990 is not a multiple of 4 hence it’s not a leap year.

HackerRankGPT is a software you can use on your PC, Mac, or Linux. When you're doing a coding challenge on a site like HackerRank, it quietly takes a picture of the problem you're working on. Then, it sends this picture to GPT-4 to get the answer. After that, it sends the solution to another device you've set up, like a tablet, phone, or another computer. This way, if you get stuck, you can look at the solution on this other device for help.

HackerRankGPT supports all languages and frameworks that GPT-4 is familiar with, practically covering a wide range. This includes Python, SQL, Java, C, C++, JavaScript, TypeScript, as well as logical and database problem solving. Additionally, it supports Ruby, Swift, PHP, Go, Kotlin, R, MATLAB, Perl... This comprehensive compatibility ensures users can tackle a diverse range of coding challenges across different platforms.

By default, HackerRankGPT is configured to work with HackerRank coding tests. However, if you are interested in using this tool on other platforms, please contact us at [email protected] . We will provide you with a version that is compatible with the platform of your choice.

Definitely NOT . HackerRank cannot detect that you are using this tool. HackerRankGPT operates entirely at the system level on your PC, Mac, or Linux, separate from your web browser. This makes it invisible to HackerRank’s cheat detection systems. Furthermore, the solution to your coding challenge is displayed on a separate device, like a mobile phone, tablet, or another computer, which prevents any screen-sharing issues during interviews. 

Since you manually type out the solution from another device, there's no suspicious clipboard activity or tab-switching that could be flagged by HackerRank's anti-cheat mechanisms. Your HackerRank window remains the active window throughout the test, further ensuring that the tool’s usage remains undetectable.

To ensure secure and undetectable operation during your coding test. The second device lets you view solutions without screen sharing them during a test, helps avoid behaviors like clipboard use and tab switching that might trigger cheat detection, and keeps the test window focused on your main device. This setup allows for discreet reference to solutions and maintains the integrity of your primary testing environment.

Yes, the tool is compatible with Windows, Mac, and Linux operating systems. It operates at the system level, ensuring functionality across these different platforms.
