ZYBOOOKS CODE

$(1)$ Prompt the user to enter a string of their choosing. Store the text in a string. Output the string. $(1$ pt$)$

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. $(1$ pt$)$

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. $(1$ pt$)$

$(4)$ 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 $\text{'}$q$\text{'}.$ Hint: Implement Quit before implementing other options. $(1$ pt$)$

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. $(4$ pts$)$

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 punctuation

s $-$ 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. $(3$ pts$)$

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. $(3$ pts$)$

Ex:

Number of letters capitalized: $3$

Edited text: We'll continue our quest in space. There will be more shuttle flights
