Question

1. Write a python3 function random_setence to implement a sentence comprised of length <=7 randomly generated words. Have this be implemented 5 times. Then let the user try and type out the sentence as fast as they can. After each successful copy of the sentence by the user, have the program sleep for a few seconds and generate a new random sentence while the user waits. Then repeat the previous 2 steps for 5 times. Finally write a function called write_results to record the time it takes the user to correctly copy the sentence every time, and output the results to a file called “times.txt”,

with the each sentence and the time to complete each and finally calculate the average time. The format should look similar to this:

Sentence                        Time to complete             

“….”                                 “time”                                   

“….”                                 “time”                                   

“….”                                 “time”                                   

“….”                                 “time”                                   

“….”                                 “time”                       

Average: average time

Here is the answer for your question in PYTHON programming language.

CODE:

#importing required modules import random import time #creating two lists to store sentences and time_taken for each sentences = [] time_took = [] #random_sentence method that returns a randomly generated senence def random_sentence(): #################################################### #Words to create a sentnece articles = ("The","A","The","A") nouns = ("dog","cat","mouse","rabbit") verb = ("is","was","was","is") adv = ("fastly","slowly","hungrily","fastly") verbs = ("running","walking","searching","jumping") prep = ("towards","on","for","on") inter = ("corridor","wall","cheese","bushes") ###################################################### #Number generated randomly between 0 and 4 #I took the random range as 0 to 4 because there are four possible words in each parts of speech num = random.randrange(0,4) #As you asked for sentence with <=7 words I choose 7 words as my choice #You can choose whatever the length of sentence you want #Choosing word at random number index from all parts of spech and storing it in the sentence sentence = articles[num] + " " + nouns[num] + " " + verb[num] + " " + adv[num] + " " + verbs[num] + " " +prep[num]+ " " + inter[num] #returing the generated sentece return sentence #j variable initialised to 0 for loop requirement j = 0 #write_results function that takes two lists sentences and time_took lists as arguments def write_results(list_sentence , time_taken): #Statements to be printed for unserstanding print("\n---------\t\t\t\t\t\t\t ----------------") print("Sentnece \t\t\t\t\t\t\t Time to complete") print("---------\t\t\t\t\t\t\t ----------------") #Initially the average and time_taken are set to 0.00 average = 0.00 total_time = 0.00 #loop to repeat for 5 times for j in range(5): #Printing jth element of list_sentence and jth element of time_take converting it to string print(list_sentence[j] + "\t\t\t\t\t\t\t " + str(time_taken[j])) #Adding time_taken to total_time at each iteration total_time = total_time +time_taken[j]; #Finally the average is total_time by 5 average = total_time/5; #Rounding avaerage to 2 decimal points average = round(average ,2) #Printing average time taken print("\nAverage time taken is :"+str(average)) #Creating variable i an initialising it to 1 i = 1 #loop that repeats for 5 times while i <=5: #Each iteration calls random_sentence() and stores the resulted sentence in sentence variable sentence = random_sentence() #Printing the sentence print(sentence) #Calculating start time from which user starts typing start = time.time() #Prompting user for input enter_sent = input("Rewrite the sentence\n") #Calculating end time when user completes end = time.time() #calculating time _taken time_taken = end - start #rounding it to 2 decimals time_taken = round(time_taken,2) #loop that repeats until the user types the same sentence while 1: #If same sentence is typed the sentence is added to sentences list #and time taken is added to time_took list #printing the time_taken and exiting the while loop if sentence == enter_sent: sentences.append(sentence) print("Time taken" +str(time_taken)) time_took.append(time_taken) break #Else asking the user for retype the sentence again else: print("Typed Wrong \n") #calculating starting and ending time start = time.time() enter_sent = input("Rewrite the sentence\n") end = time.time() time_taken = end - start #incrementing i value for each iteration i = i+1 #calling wrte_results function finally write_results(sentences,time_took)
