In this coding challenge, you will be retrieving email usernames from a string. You will write a function named get_usernames () that takes in a string as it's input parameter, and returns a list of email usernames in the string. The input strings will contain 0 or more emails in the format and the '@' symbol will only appear in the context of an email. The order of usernames should match the order in the input text. username@domainname, For example: EXAMPLE 1 text: "If you need help on an assignment, email help@ucsd.edu or support@gmail.com" return: ['help', 'support'] EXAMPLE 2 text: "Good morning!

Write a function called generate_initials() which takes a string as input, where the string represents someone's full name. The function should return a string containing the initials of that person. The initials are simply the first letter of each part of the name that is separated by a space. If the input string does not contain any space characters, then it is not possible to generate initials. In this case, the function should raise a ValueError with the error message "ERROR: Invalid name!". Note: You *must* use 'raise' in your solution. For example: Test Result print(generate_initials ('Paul Denny')) PD try: ERROR: Invalid name! print(generate_initials(' Paul')) except ValueError as e: print(e) Answer: (penalty regime: 0, 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 %)
Questions P17 and P18 are related to the code skeleton of the function below. The function readPeople() below takes a string fname as an argument, which is the name of a file containing information about people on each line. The function returns a dictionary containing all of the information contained in the file. Each line of the file contains three items of information about a person: ID number, name, and age. The information stored in each dictionary entry should be the name and age of a person, and it should be associated with a key which is the ID number of that person. def readPeople(fname): infile = open(fname, "r") pDict = {} _______[P17]_______ ldat = l.split() _______[P18]_______ return(pDict) An example file is shown below.example.txt1234 Joe 242345 Jane 353456 Pete 22Assume that the ID numbers are unique for each person.

Write a function validate_date(date_string) which takes in a datestring and checks if the datestring is valid. If the string is valid, we want to return a tuple containing True and the date_string itself. If the string is invalid for a specific reason, we want to return a tuple containing False and the error code explaining what was wrong with the date string passed in. Below is the error codes for reasons why a string can be invalid (based on criteria on validity, read above): -1 --> date_string does not separate the day, month, and year with slashes. -2 --> day, month, or year are not numeric. -3 --> month out of range (not between 1 and 12) -4 --> day is out of range (not between 1 and last day of the month) For instance, if validate_date(date_string) is called with "01/12/2022" as the argument, the return value is (True, "01/12/2022") because "01/12/2022" is a valid string. If validate_date(date_string) is called with "01/44/2022" as the argument, the return value is…
Write a function which will take 2 arguments. They are: • Sentence • position Your first task is to take these arguments as user input and pass these values to the function parameters. Your second task is to implement the function and remove the characters at the index number which is divisible by the position (Avoid the index number 0 as it will always be divisible by the position, so no need to remove the index 0 character). Finally, add the removed characters at the end of the new string. Return the value and then finally, print the new string at the function call. Input: "I love programming." 3 Function call: function_name("I love programming.", 3) Output: I lveprgrmmngo oai. Input: "Python is easy to learn. I love python." 6 Function call: function_name("Python is easy to learn. I love python.", 6) Output: Pythonis eay to earn.l lov pythn. sl eo
Write a function, named randomPassword, that generates a random password that takes no parameter. It will return the randomly generated password as its ONLY result. Display the randomly generated password in the main program. Password Criteria: o The password should have a random length of between 7 and 10 characters. o Each character should be randomly selected from positions 33 to 126 from the ASCII table You must import randint function directly and inline within the random package and it must be the first line of code in your program, after your program header comment. o Declaring and using FOUR constants. Constants must be named appropriately and intuitively. o You must use the chr built-in function within your randomPassword function: o Declaring the main function and invoking randomPassword function. o Logical approach to problem solving, computation, and displaying appropriate output.
Complete the check_character() function which has 2 parameters: A string, and a specified index. The function checks the character at the specified index of the string parameter, and returns a string based on the type of character at that location indicating if the character is a letter, digit, whitespace, or unknown character. Ex: The function calls below with the given arguments will return the following strings: check_character('happy birthday', 2) returns "Character 'p' is a letter"check_character('happy birthday', 5) returns "Character ' ' is a white space"check_character('happy birthday 2 you', 15) returns "Character '2' is a digit"check_character('happy birthday!', 14) returns "Character '!' is unknown" use python please def check_character(word, index): # Type your code here. if __name__ == '__main__': print(check_character('happy birthday', 2)) print(check_character('happy birthday', 5)) print(check_character('happy birthday 2 you', 15))…
You are asked to write a python code that can translate a word from English to French of the following words: English French the le the la book livre apple pomme Thus, you need to write a function named Translation that translates a word from English to French. The function will take two parameters as input a dictionary and the English word, and It will return a (possibly empty) french word. The program should create a dictionary that represents the table above and then show that the Translation function works correctly when it returns multiple keys, a single key, and no keys. Example: • The French words for 'the' are: ['le', 'la'] • The French word for 'apple' is: ['pomme'] • The French word for 'asdf' is: [] Note: The use of a large number of if/elif/else conditions is not allowed.
Complete the process_name() function that takes a single string parameter name. You can assume that the name will always be in the format first name surname with a single space character between the first name and the surname. The function returns a string consisting of the first letter of the first name followed by the first three letters of the surname. All of the characters in the returned string should be in lowercase. Some examples of the function being used are shown below: For example: Test Result print(process_name("Damir Azhar")) dazh print(process_name("Ann Cameron")) acam Answer: (penalty regime: 0 %) Reset answer 1v def process_name (name): 2
Write a function that takes two arguments: stock and ingr (short for ingredients) and returns the missing ingredients in stock. stock is a dictionary containing (key,value) pairs in the form of ("potato", 5). The key is the name of an ingredient, and the vlaue is its existing amount. ingr is a list of tuples, where each tuple represents the required amount of an ingredient. For example, ("cheese", 3) means we need 3 units of cheese for this recipe. Your function checks whether we have enough of each item in the stock. If an item is missing or not enough then your function returns the missing amount within a list of all such items. If all items are in stock, then you return an empty list. For example: stock = {"salt":100, "sugar":100, "flour":50, "apple":3, "cream":10} ingr = [("sugar",50), ("flour", 120), ("apple",5)] checkStock(stock, ingr) should return [("flour",70), ("apple",2)] which means we need 70 more units of flour and 2 more apples for this recipe. Note that it is possible…
