Using regular expression, return the last four digits in a phone number. Create a function to demonstrate how you would go about doing this (pass the phone number as the function parameter)

Objectives Practice defining functions with parameters. Practice manipulating strings. Implement your own version of Python string methods The provided file string_functions.py defines several string functions, but does not include the code for them. Add code to implement functions that are equivalent in behavior to the corresponding built-in Python string function. Every function MUST return a value. Use loops to implement your functions. You cannot use built-in string methods, string functions, or string-operators to implement your functions. Each function is worth a maximum of 10 points. 1. cs110_upper: Takes a string as a parameter and returns it as a string in all uppercase. Hint: Use the ord () function to get the ASCI value of a character. For example, ord ('a') returns the integer 97. You will also need to use the chr (value) function that returns a string of one character whose ASCII code is the integer valus. For example, chr (97) returns the string 'a'. You cannot use the…

I need help solving this in PYTHON

Add a function to get the CPI values from the user and validate that they are greater than 0. 1. Declare and implement a void function called getCPIValues that takes two float reference parameters for the old_cpi and new_cpi. 2. Move the code that reads in the old_cpi and new_cpi into this function. 3. Add a do-while loop that validates the input, making sure that the old_cpi and new_cpi are valid values. + if there is an input error, print "Error: CPI values must be greater than 0." and try to get data again. 4. Replace the code that was moved with a call to this new function. - Add an array to accumulate the computed inflation rates 1. Declare a constant called MAX_RATES and set it to 20. 2. Declare an array of double values having size MAX_RATES that will be used to accumulate the computed inflation rates. 3. Add code to main that inserts the computed inflation rate into the next position in the array. 4. Be careful to make sure the program does not overflow the array. - Add a…

C++ question You work with emergency services in Britain and the emergency number just changed: Yikes! That’s a big change. What if the number changes again? Let’s build a function that prints out the current emergency number, whatever it is from now on. Above main(), define a voidfunction get_emergency_number()that accepts one parameter: a string with the name emergency_number

Please tell me where I get wrong.

Describe how to pass an array as a parameter to a function.

Python Programming: Write a program using unittest.TestCase methods to confirm that the addition and subtraction of date and timedelta objects produce correct results.  Important notes: Use the unittest module to create a TestCase to test that the addition and subtraction of date and timedelta objects produce correct results... For example I could create a TestCase with a function that tests the addition of date and timedelta objects; a function that tests the subtraction of date and timedelta and then call unittest's main method at the end. When you run this program, it should tell us whether the text was successful or not. See attached image for what the output should look like.
