The objective of this question is to generate and read files that contain a list of random numbers. Write a function that generates a file with following parameters: def fillFile(fileSize, fileName): The function should be called to generate files in the following sizes: fileSizes = [1000, 5000, 10000, 25000, 50000, 100000, 200000] The generated files can have names file1000, file5000, file10000, file25000, file50000, file100000, file200000. Each file should have serial numbers from 0 to size of file. By using one tenth of file shuffle numbers among themselves. For example, if your file 100 numbers, choose 10 numbers randomly and shuffle these numbers. You can use random.randint(0,fileSize+1000) to generate a random number. Write another function that reads numbers inside of a file and returns a list. def readFile(fileName): The returned list contains the numbers stored in the file. At each call of fillFile and readFile, record the times before and after the function call as in following example (import time) : start = time.time() fillFile(fileSize, “file” + str(fileSize)) finish = time.time() runTime = finish – start Record the run times of functions into a file named “fileStats.txt”. The “fileStats.txt” file should contain entries for run times as follows: fillFile n1, n2, n3, n4, n5, n6, n7 readFile n1, n2, n3, n4, n5, n6, n7 where n1, n2, n3, n4, n5, n6 and n7 are execution times for file sizes 1000, 5000, 10000, 25000, 50000, 100000, 200000. Submit your program code and filleStats.txt in ZIP file together with the solutions of other programs.
The objective of this question is to generate and read files that contain a list of random numbers. Write a function that generates a file with following parameters:
def fillFile(fileSize, fileName):
The function should be called to generate files in the following sizes:
fileSizes = [1000, 5000, 10000, 25000, 50000, 100000, 200000]
The generated files can have names file1000, file5000, file10000, file25000, file50000, file100000, file200000. Each file should have serial numbers from 0 to size of file. By using one tenth of file shuffle numbers among themselves. For example, if your file 100 numbers, choose 10 numbers randomly and shuffle these numbers.
You can use random.randint(0,fileSize+1000) to generate a random number.
Write another function that reads numbers inside of a file and returns a list.
def readFile(fileName):
The returned list contains the numbers stored in the file.
At each call of fillFile and readFile, record the times before and after the function call as in following example (import time) :
start = time.time()
fillFile(fileSize, “file” + str(fileSize))
finish = time.time()
runTime = finish – start
Record the run times of functions into a file named “fileStats.txt”. The “fileStats.txt” file should contain entries for run times as follows:
fillFile n1, n2, n3, n4, n5, n6, n7
readFile n1, n2, n3, n4, n5, n6, n7
where n1, n2, n3, n4, n5, n6 and n7 are execution times for file sizes 1000, 5000, 10000, 25000, 50000, 100000, 200000.
