- Cyclops numbersdef is_cyclops(n):A nonnegative integer is said to be a cyclops number if it consists of an odd number of digits so that the middle (more poetically, the “eye”) digit is a zero, and all other digits of that number are nonzero. This function should determine whether its parameter integer n is a cyclops number, and return either True or False accordingly n Expected result 0 True 101 True 98053 True 777888999 False 1056 False 675409820 FalsecapCount.py make a program called capCount.py that has a function that takes in a string and prints the number of capital letters in the first line, then prints the sum of their indices in the second line.

- ATM machines allow 4 or 6 digit PIN codes and PIN codes cannot contain anything but exactly 4 digits or exactly 6 digits. Your task is to create a function that takes a string and returns true if the PIN is valid and false if it's not. Examples validatePIN("1234") ➞ true validatePIN("12345") ➞ false validatePIN("a234") ➞ false validatePIN("") ➞ false Notes ● Some test cases contain special characters. ● Empty strings must return false.In C programming language Question (Strings) Write a function find_Substring() that finds a substring into a string. Pass array s1 and s2 to this function and prints if the substring is present or not. Expected Output 1: Enter string This is a javascript Enter substring script The substring is present Expected Output 2: Enter string This is a javascript Enter substring Jscript The substring is not present3. Complete the function count_digits. This function takes one parameter - a string (s). It should return the number of digits in s. For example, if s is "25 or 6 to 4 is a song by Chicago" then count_digits should return 4. count_digits should not print the result- it should return it. Do not change anything outside count_digits.

- A spoonerism is when the first letters / sounds of two words are transposed onto one another. Create a function that takes a two-word string and performs a spoonerism on the phrase. Examples spoonerise ("history lecture") "listory hecture" spoonerise("loud noises") → "noud loises" spoonerise("chow mein") → "mow chein" spoonerise ("edabit rules!") Notes → "redabit ules!" • Only two words will be parsed into the function. Don't worry about handling more than two. • You won't always just have to swap the first letters, take care to notice which letters have been switched in the examples (notice the difference between vowel-starting and consonant-starting words).Topics: User-defined functions, list, string, docstringProblem Statement: This program finds the unique letters from a given string and printsthe unique letters and their count. For example: word ‘LITTLE’ has ‘L’, ‘I’, ‘T’, ‘E’ are theunique letters.Lab Scenario:The program repeats until hits ‘n’. The program takes a user input of a string. The programfinds the unique letters in the string, add them in a list and displays the list and their count.Consider the following important points:1) You need to design a user-defined function named count_unique_letters whichtakes user word as parameter and returns the list of unique letters calledunique_letters in the given word.a. Hint: Iterate over each letter in user word, check if the letter is in the list, if notadd it to the list, otherwise continue to the next letter. A ‘in’ keyword can helpto determine if a character in the unique_letters list.b. You need to write a simple docstring for this function.2) Your program must have a main()…please code in pythonis_phone_num: This Boolean function takes a string and returns True if it is in the formatddd-ddd-dddd, where d is a digit, False otherwise. Example calls:is_phone_num('123-456-7890') --> Trueis_phone_num('123-4556-7890') --> Falseis_phone_num('(123)456-7890') --> False
- When you pass null as an argument to the Split function of a string object, what characters are used as delimiters?capCount.py by using "sys.argv" ● Create a program called capCount.py that has a function that takes in a string and prints the number of capital letters in it.def swap_text(text): Backstory: Luffy wants to organize a surprise party for his friend Zoro and he wants to send a message to his friends, but he wants to encrypt the message so that Zoro cannot easily read it. The message is encrypted by exchanging pairs of characters. Description: This function gets a text (string) and creates a new text by swapping each pair of characters, and returns a string with the modified text. For example, suppose the text has 6 characters, then it swaps the first with the second, the third with the fourth and the fifth with the sixth character. Parameters: text is a string (its length could be 0)Return value: A string that is generated by swapping pairs of characters. Note that if the Examples: swap_text ("hello") swap_text ("Party for Zoro!") swap_text ("") def which_day(numbers): → 'ehllo'→ 'aPtr yof roZor!' → '' length of the text is odd, the last character remains in the same position.
