Python Answers

Temperature Conversion:-

You are given the temperature T of an object in one of Celsius, Fahrenheit, and Kelvin scales.

Write a program to print T in all scales viz Celsius, Fahrenheit, and Kelvin.

Formula to convert from Fahrenheit F to Celsius C is C = (F - 32) * 5 / 9.

Formula to convert from Kelvin K to Celsius C is C = K - 273.

Here "C", "F", "K" represent that the temperature scale is in Celsius, Fahrenheit and Kelvin scales respectively.

The input contains the temperature (a number) and the unit of the temperature scale (C, F, K) without any space.

The output contains temperature in Celsius, Fahrenheit and Kelvin scales in each line in the format similar to input and the value of the temperature is rounded to 2 decimal places.

Largest Palindrome

You are given an integer

N. Find the largest palindrome which is less than N.Input

The input contains a single integer

N.Output

The output should be a single integer which is the largest palindrome that is less than the given input.

Explanation

Given

N = 45.44 is the largest number which is a palindrome that is less than 45.

Write a program to count Vowels and Consonants in string.

Given a string, write a program to return the sum and average of the digits of all numbers that appear in the string, ignoring all other characters.

Given an integer N as a starting number and K as input, write a python program to print a number pyramid of K rows as shown

In the example, the given starting number is

10, and the number of rows in the pyramid is 5.So, the output should be

10

11 12

13 14 15

16 17 18 19

20 21 22 23 24

Build an algorithm to parse and process the dynamic expression based on the dictionary

provided. The expression basically consists of Operators, Variables, and Parentheses.

Parentheses have higher precedence (i.e the subexpression in the parentheses should be

executed first)

Basically, the algorithm should support two operators - AND (concatenates the two variables) &

OR (provides first variable value if it is available. Otherwise, go for the second variable)

The algorithm should parse the given expression and apply the respective dictionary values on

the expression and provides the respective computed results.
