# SoloLearn Python Core: celsius to fahrenheit converter code project answer

Code project answer of  SoloLearn mobile Application and project celsius to fahrenheit converter code from Python Core course. celsius = int(input()) def conv(c):      celsius = c f = 9/5 * celsius + 32 return f fahrenheit = conv(celsius) print(fahrenheit) In this code we just need to declare a variable, we can name it as 'f' and assign values of equation of Fahrenheit to Celsius convertor equation (9/5 * Celsius + 32), and return that variable f and print it. What is happening here is. In the first line we take one 'int' or 'whole number' as input and then we call the function 'conv' which returns converted value f. Then we simply take or copy that return variables data to our new variable called 'fahrenheit', and then we are going to print it.

# How to count walking steps accurately in smartphones

In smart phone padometer or counting walking steps application is easily available on their platform specific app store i.e On android it is called playstore. Most of the time when we think about this walking exercise we choose to purchase specific wearable exercise gadgets. i.e Expensive smart watch or fitness belt. you might not  aware that we can track and trace physical activity on smartphone like android and apple also. In smartphone, same sensor named accelerometer and gyroscope utilized to accomplish this task. How to position smartphone to track and trace walking steps accurately: Smartphone position to count walking steps 1. Download application, mostly one of named "Padometer"or "StepCounter on your smartphone. 2. First manually count(counting without smartphone) max 100 steps walking distance for calibration. 3. Now turn on the application. 4. In most of the application go to settings and set the sensory sensitivity to nearest to 50% 5. Hold perfect tight you

# Sololearn Python Core code project FizzBuzz answer

FizzBuzz is a well known programming assignment, asked during interviews.The given code solves the FizzBuzz problem and uses the words "Solo" and "Learn" instead of "Fizz" and "Buzz". It takes an input n and outputs the numbers from 1 to n. For each multiple of 3, print "Solo" instead of the number. For each multiple of 5, prints "Learn" instead of the number. For numbers which are multiples of both 3 and 5, output "SoloLearn".  You need to change the code to skip the even numbers, so that the logic only applies to odd numbers in the range. Ans. for x in range(1, n , 2): if x % 3 == 0 and x % 5 == 0: print("SoloLearn") continue elif x % 3 == 0: print("Solo") continue elif x % 5 == 0: print("Learn") continue else: print(x)
