Question
Transcribed Image Text:Instructions
The python "try" keyword is very powerful in that it can, among other things, prevent a program from ending abnormally because of
invalid numeric input.
Write a python program with two functions/modules that does the following:
.main() accepts input and calls a function to test if the input is a number and displays a message regarding the result of that
numeric test
• numTest() is passed an input string, tests to see if the string is numeric and returns the necessary information to main()
. a NULL input (just pressing the enter key) ends the program
. DO NOT USE THE BUILTIN PYTHON FUNCTION FOR NUMERIC TESTING
Be sure to use clear prompts/labeling for input and output.

- PYTHON Question 3: Rain or Shine Part 1: Alfonso will only wear a jacket outside if it is below 60 degrees or it is raining. Write a function that takes in the current temperature and a boolean value telling if it is raining and it should return True if Alfonso will wear a jacket and False otherwise. Try solving this problem with a single line of code. def wears_jacket(temp, raining): """ >>> wears_jacket(90, False) False >>> wears_jacket(40, False) True >>> wears_jacket(100, True) True """ *** YOUR CODE HERE *** Note that it should either return True or False based on a single condition, whose truthiness value will also be either True or False. Part 2: Rewrite the above function with a lambda expression.arrow_forwardA header of a C-language function is: void recurs(int current_level, int max_level ) The keyword "void" here signifiesarrow_forwardIn Python how would you return a value from a function?arrow_forward
- C++ - No library functions like atoi Write a machine language program to output your first name on the output device. Submit your "machine code" followed by a 'zz.' An example of the machine code to output "hello" is shown below. This is an example of what a machine language submission would look like: 50 00 48 50 00 65 50 00 6c 50 00 6c 50 00 6f 00 zzarrow_forwardWould these be equivalent?

Sample run: Even or Odd Checker Enter an integer: 33 This is an odd number. Specifications Store the code that gets user input and displays output in the main function. Store the code that checks whether the number is even or odd in a separate function. validate the use inputs, only integers accepted, give the user an option to enter again, ask the user if wants to try again.arrow_forwardin c programing with User-Defined Functions Remove all non-alphabetic characters Write a program that removes all non-alphabetic characters from the given input. Assume the input string will not exceed 50 characters. Ex: If the input is: -Hello, 1 world$! the output is: Helloworld The program must define and call a function named RemoveNonAlpha that takes two strings as parameters: userString and userStringAlphaOnly. userString is the user specified string from the program input. Function RemoveNonAlpha() then assigns userStringAlphaOnly with the user specified string without any non-alphabetic characters.void RemoveNonAlpha(char userString[], char userStringAlphaOnly[])arrow_forward
