Write a Python program to find numbers between 100 and 400 (both included) where each digit of a number is an even number. The numbers obtained should be printed in a comma-separated sequence. Click me to see the sample solution 17. Alphabet Pattern 'A' Write a Python program to print ...

You could create 26 variables, one for each letter of the alphabet. Then you could traverse the string and, for each character, increment the corresponding counter, probably using a chained conditional. You could create a list with 26 elements. Then you could convert each character to a numbe...

A Caesar cipher shifts each letter by a number of letters. For example, if you shift the letter a by three, then you get the letter d, and so on.If the shift goes beyond the end of the alphabet, then you just need to rotate back to the beginning of the alphabet. In the case ...
Write a Python program to find the missing numbers in a sequence of digits where a complete range is expected. Write a Python program to identify the missing letters from a string that should contain every letter of the alphabet. Write a Python program to determine which vowels are absent fro...
