In Python, write a words-per-minute(WPM) typing test. Weve provided the following functions:

• select_sentence. Returns a randomly-chosen sentence, one of the ones described above. (If you call this function multiple times, it might return the same sentence more than once; thats expected and totally fine.)

• count_word. Returns the number of words in a given sentence. It cares only about spaces to separate words.

• count_mismatches. Returns the number of word-mismatches between two sentences. Punctuation and case matter. If one sentence is Hello World! and the other is Hello World?, that is a mismatch count of one, because Hello is typed correctly but World! is not .

Youll use these functions to put together a program that does the following:

• Gives the user sentences to type, until they type DONE and then the test is over.

• Counts the number of seconds from when the user begins to when the test is over.

• Counts and prints:

  • The total number of words the user typed, and how many seconds it took them.

  • The words-per-minute that turns out to be.

  • The number of mistakes they made.

  • The adjusted words-per-minute, accounting for mistakes.

WPM and adjusted WPM... Suppose the user types 25 words and it takes them 30 seconds. That would be 50 words per minute. But if they made two mistakes, then we say they typed 23 words in 30 seconds, and so adjusted WPM is 46.

The number of mistakes is always subtracted from the total words typed, regardless of whether it was a misspelled word, an extra word, or a missing word.

Requirements:

• The number of words typed and number of mistakes made should should be integers throughout the program. The words per minute and adjusted words per minute, when reported on the terminal, should be rounded to the nearest whole number.

• The number of seconds should be rounded to the nearest 100th.

• The test must keep going, selecting sentence after sentence after sentence until the user types DONE.

• The user might type DONE at the very beginning and just get zeroes for everything.

Hints:

• Python has a time module that youll probably find useful.

• You should prompt the user to just type Enter at the beginning, and start the timer right after that.

• You should stop the timer right after they type DONE (dont worry about any extra little bits of time it took them to type DONE).
