 Reading ints safely Reading ints safely Objectives improving the student's skills in defining functions; using exceptions in order to provide a safe input environment. Scenario Your task is to write a function able to input integer values and to check if they are within a specified range. LAB Sandbox The function should: accept three arguments: a prompt, a low acceptable limit, and a high acceptable limit; if the user enters a string that is not an integer value, the function should emit the message Error: wrong input, and ask the user to input the value again; if the user enters a number which falls outside the specified range, the function should emit the message Error: the value is not within permitted range (min..max) and ask the user to input the value again; if the input value is valid, return it as a result. Test data Test your code carefully. This is how the function should react to the user's input: Enter a number from -10 to 10: 100 Error: the value is not within per...

 Find a Word in a Combination of Characters Find a word game Objectives improving the student's skills in operating with strings; using the find() method for searching strings. Scenario Let's play a game. We will give you two strings: one being a word (e.g., "dog") and the second being a combination of any characters. Your task is to write a program which answers the following question: are the characters comprising the first string hidden inside the second string? For example: if the second string is given as "vcxzxduybfdsobywuefgas", the answer is yes; if the second string is "vcxzxdcybfdstbywuefsas", the answer is no (as there are neither the letters "d", "o", or "g", in this order) Hints: you should use the two-argument variants of the pos() functions inside your code; don't worry about case sensitivity. Test your code using the data we've provided. Test data Sample input: donor Nabucodonosor Sample output:...

 The Digit of Life The digit of life Life Path Number Calculator To know your life path number, You need to enter your birth date as numbers only to calculate your life path number. You should add the digits of the month, day, and year until you arrive at a single digit number. How digit of life  is calculated Let's see the lab question. Objectives improving the student's skills in operating with strings; converting integers into strings, and vice versa. Scenario Some say that the Digit of Life is a digit evaluated using somebody's birthday. It's simple - you just need to sum all the digits of the date. If the result contains more than one digit, you have to repeat the addition until you get exactly one digit. For example: 1 January 2017 = 2017 01 01 2 + 0 + 1 + 7 + 0 + 1 + 0 + 1 = 12 1 + 2 = 3 3 is the digit we searched for and found. Your task is to write a program which: asks the user her/his birthday (in the format YYYYMMDD, or YYYYDDMM, or MMDDYYYY - actually, the ...

 Anagrams Anagram Listen = Silent [1] An anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once.[1] For example, the word binary into brainy and the word adobe into abode. The original word or phrase is known as the subject of the anagram. Any word or phrase that exactly reproduces the letters in another order is an anagram. Now, lets see the lab question. Scenario An anagram is a new word formed by rearranging the letters of a word, using all the original letters exactly once. For example, the phrases "rail safety" and "fairy tales" are anagrams, while "I am" and "You are" are not. Your task is to write a program which: asks the user for two separate texts; checks whether, the entered texts are anagrams and prints the result. Note: assume that two empty strings are not anagrams; treat upper- and lower-case letters as equal; spaces are not taken into acc...

Python: Check If a String is a Palindrome Palindrome Objectives improving the student's skills in operating with strings; encouraging the student to look for non-obvious solutions. Scenario Do you know what a palindrome is? It's a word which look the same when read forward and backward. For example, "kayak" is a palindrome, while "loyal" is not. Your task is to write a program which: asks the user for some text; checks whether the entered text is a palindrome, and prints result. Note: assume that an empty string isn't a palindrome; treat upper- and lower-case letters as equal; spaces are not taken into account during the check - treat them as non-existent; there are more than a few correct solutions - try to find more than one. Test your code using the data we've provided. Test data Sample input: Ten animals I slam in a net Sample output: It's a palindrome Sample input: Eleven animals I slam in a net Sample output: It's not a palindrome So...
