Python (1) Prompt the user to enter a string of their choosing. Store the text in a string. Output the string.Ex:Enter a sample text: we'll continue our quest in space. there will be more shuttle flights and more shuttle crews and,yes; more volunteers, more civilians, more teachers in space. nothing ends here; our hopes and our journeyscontinue! You entered: we'll continue our quest in space. there will be more shuttle flights and more shuttle crewsand, yes; more volunteers, more civilians, more teachers in space. nothing ends here; our hopes and our journeyscontinue!(2) Implement the print_menu() function to print the following command menu.Ex:MENU c - Number of non-whitespace characters w - Number of words f - Fix capitalization r - Replace punctuations - Shorten spaces q -Quit(3) Implement the execute_menu() function that takes 2 parameters: a character representing the user's choice andthe user provided sample text. execute_menu() performs the menu options, according to the user's choice, by callingthe appropriate functions described below.(4) In the main program, call print_menu() and prompt for the user's choice of menu options for analyzing/editingthe string. Each option is represented by a single character.If an invalid character is entered, continue to prompt for a valid choice. When a valid option is entered, execute theoption by calling execute_menu(). Then, print the menu and prompt for a new option. Continue until the user enters'q'. Hint: Implement Quit before implementing other options.Ex:MENU c - Number of non-whitespace characters w - Number of words f - Fix capitalization r - Replace punctuations - Shorten spaces q - Quit Choose an option:(5) Implement the get_num_of_non_WS_characters() function. get_num_of_non_WS_characters() has a stringparameter and returns the number of characters in the string, excluding all whitespace. Callget_num_of_non_WS_characters() in the execute_menu() function, and then output the returned value.Ex:Enter a sample text: we'll continue our quest in space. there will be more shuttle flights and more shuttle crews and,yes; more volunteers, more civilians, more teachers in space. nothing ends here; our hopes and our journeyscontinue! You entered: we'll continue our quest in space. there will be more shuttle flights and more shuttle crewsand, yes; more volunteers, more civilians, more teachers in space. nothing ends here; our hopes and our journeyscontinue! MENU c - Number of non-whitespace characters w - Number of words f - Fix capitalization r - Replacepunctuations - Shorten spaces q - Quit Choose an option: c Number of non-whitespace characters: 181(6) Implement the get_num_of_words() function. get_num_of_words() has a string parameter and returns thenumber of words in the string. Hint: Words end when a space is reached except for the last word in a sentence. Callget_num_of_words() in the execute_menu() function, and then output the returned value. Ex:Number of words: 35(7) Implement the fix_capitalization() function. fix_capitalization() has a string parameter and returns an updatedstring, where lowercase letters at the beginning of sentences are replaced with uppercase letters. fix_capitalization()also returns the number of letters that have been capitalized. Call fix_capitalization() in the execute_menu()function, and then output the number of letters capitalized followed by the edited string. Hint 1: Look up and usePython functions.islower() and .upper() to complete this task. Hint 2: Create an empty string and use stringconcatenation to make edits to the string.Ex:Number of letters capitalized: 3 Edited text: We'll continue our quest in space. There will be more shuttle flights andmore shuttle crews and, yes; more volunteers, more civilians, more teachers in space. Nothing ends here; our hopesand our journeys continue!(8) Implement the replace_punctuation() function. replace_punctuation() has a string parameter and two keywordargument parameters exclamation_count and semicolon_count. replace_punctuation() updates the string byreplacing each exclamation point (!) character with a period (.) and each semicolon (;) character with a comma (,).replace_punctuation() also counts the number of times each character is replaced and outputs those counts. Lastly,replace_punctuation() returns the updated string. Call replace_punctuation() in the execute_menu() function, andthen output the edited string. (3 pts)Ex:Punctuation replaced exclamation_count: 1 semicolon_count: 2 Edited text: we'll continue our quest in space. therewill be more shuttle flights and more shuttle crews and, yes, more volunteers, more civilians, more teachers in space.nothing ends here, our hopes and our journeys continue.(9) Implement the shorten_space() function. shorten_space() has a string parameter and updates the string byreplacing all sequences of 2 or more spaces with a single space. shorten_space() returns the string. Callshorten_space() in the execute_menu() function, and then output the edited string.Ex:Edited text: we'll continue our quest in space. there will be more shuttle flights and more shuttle crews and, yes;more volunteers, more civilians, more teachers in space. nothing ends here; our hopes and our journeys continue!

Question

Python

(1) Prompt the user to enter a string of their choosing. Store the text in a string. Output the string.
Ex:
Enter a sample text: we'll continue our quest in space. there will be more shuttle flights and more shuttle crews and,
yes; more volunteers, more civilians, more teachers in space. nothing ends here; our hopes and our journeys
continue! You entered: we'll continue our quest in space. there will be more shuttle flights and more shuttle crews
and, yes; more volunteers, more civilians, more teachers in space. nothing ends here; our hopes and our journeys
continue!
(2) Implement the print_menu() function to print the following command menu.
Ex:
MENU c - Number of non-whitespace characters w - Number of words f - Fix capitalization r - Replace punctuation
s - Shorten spaces q -
Quit
(3) Implement the execute_menu() function that takes 2 parameters: a character representing the user's choice and
the user provided sample text. execute_menu() performs the menu options, according to the user's choice, by calling
the appropriate functions described below.
(4) In the main program, call print_menu() and prompt for the user's choice of menu options for analyzing/editing
the string. Each option is represented by a single character.
If an invalid character is entered, continue to prompt for a valid choice. When a valid option is entered, execute the
option by calling execute_menu(). Then, print the menu and prompt for a new option. Continue until the user enters
'q'. Hint: Implement Quit before implementing other options.
Ex:
MENU c - Number of non-whitespace characters w - Number of words f - Fix capitalization r - Replace punctuation
s - Shorten spaces q - Quit Choose an option:
(5) Implement the get_num_of_non_WS_characters() function. get_num_of_non_WS_characters() has a string
parameter and returns the number of characters in the string, excluding all whitespace. Call
get_num_of_non_WS_characters() in the execute_menu() function, and then output the returned value.
Ex:
Enter a sample text: we'll continue our quest in space. there will be more shuttle flights and more shuttle crews and,
yes; more volunteers, more civilians, more teachers in space. nothing ends here; our hopes and our journeys
continue! You entered: we'll continue our quest in space. there will be more shuttle flights and more shuttle crews
and, yes; more volunteers, more civilians, more teachers in space. nothing ends here; our hopes and our journeys
continue! MENU c - Number of non-whitespace characters w - Number of words f - Fix capitalization r - Replace
punctuations - Shorten spaces q - Quit Choose an option: c Number of non-whitespace characters: 181
(6) Implement the get_num_of_words() function. get_num_of_words() has a string parameter and returns the
number of words in the string. Hint: Words end when a space is reached except for the last word in a sentence. Call
get_num_of_words() in the execute_menu() function, and then output the returned value.

Ex:
Number of words: 35
(7) Implement the fix_capitalization() function. fix_capitalization() has a string parameter and returns an updated
string, where lowercase letters at the beginning of sentences are replaced with uppercase letters. fix_capitalization()
also returns the number of letters that have been capitalized. Call fix_capitalization() in the execute_menu()
function, and then output the number of letters capitalized followed by the edited string. Hint 1: Look up and use
Python functions.islower() and .upper() to complete this task. Hint 2: Create an empty string and use string
concatenation to make edits to the string.
Ex:
Number of letters capitalized: 3 Edited text: We'll continue our quest in space. There will be more shuttle flights and
more shuttle crews and, yes; more volunteers, more civilians, more teachers in space. Nothing ends here; our hopes
and our journeys continue!
(8) Implement the replace_punctuation() function. replace_punctuation() has a string parameter and two keyword
argument parameters exclamation_count and semicolon_count. replace_punctuation() updates the string by
replacing each exclamation point (!) character with a period (.) and each semicolon (;) character with a comma (,).
replace_punctuation() also counts the number of times each character is replaced and outputs those counts. Lastly,
replace_punctuation() returns the updated string. Call replace_punctuation() in the execute_menu() function, and
then output the edited string. (3 pts)
Ex:
Punctuation replaced exclamation_count: 1 semicolon_count: 2 Edited text: we'll continue our quest in space. there
will be more shuttle flights and more shuttle crews and, yes, more volunteers, more civilians, more teachers in space.
nothing ends here, our hopes and our journeys continue.
(9) Implement the shorten_space() function. shorten_space() has a string parameter and updates the string by
replacing all sequences of 2 or more spaces with a single space. shorten_space() returns the string. Call
shorten_space() in the execute_menu() function, and then output the edited string.
Ex:
Edited text: we'll continue our quest in space. there will be more shuttle flights and more shuttle crews and, yes;
more volunteers, more civilians, more teachers in space. nothing ends here; our hopes and our journeys continue!
