Help! Please use the python code to do it. Thank you.

Question:

(1) Complete the get_num_of_characters() function, which takes a string as parameter and returns the number of characters in the user's string. We encourage you to use a for loop in this function.

(2) Implement the output_without_whitespace() function. output_without_whitespace() takes a string as parameter and outputs the string's characters except for whitespace (spaces, tabs). Note: A tab is '\t'.

(3) Write a function get_acronym() that returns the acronym for a phrase, e.g. acronym for random access memory is RAM, acronym for central processing unit is CPU.

(4) Create a main() function that first prompts the user to enter a sentence, outputs the string, and calls functions in (1) and (2) to get character counts as well as output without whitespaces; then prompts user again for a phrase and output the acronym.

(4) call the main function to run the program.

A sample input/output dialog

Enter a sentence or phrase: The only thing we have to fear is fear itself.

You entered: The only thing we have to fear is fear itself.

Number of characters: 46

String with no whitespace: Theonlythingwehavetofearisfearitself.

Enter a phrase to generate an acronym: random access memory

The acronym is: RAM

Your program structure should look like:

def get_num_of_characters(inputStr):

#your code here

return

def output_without_whitespace(inputStr) :

#your code here

return

def get_acronym (inputStr) :

#your code here

return

def main () :

#your code here

return

if __name__ == '__main__':
