Question

Create a script that take a directory path from the user. What I want you to do is figure out the total size of all files in the directory. You will need to import the os module for this.

• dirs=os.listdir(DIRECTORY) where DIRECTORY is the direction you want to look at will return a list of all files in that directory.
• You can then use a for loop to go through dirs much like you went through a range in the previous examples you saw. Start by doing this and printing out the name of each file found.
• Once you have that working create a total variable and use os.path.getsize(FILE) where FILE is the file's size you want to add the file size to total.
• Print out the total size for all files in the directory. Note that the result is in bytes.
• Use an if statement to print the total out in KB if the total is over 1024. If it is not, simply print the total in bytes.
• Finally add to your program to also calculate the average size of a file in the given directory.

BELOW IS THE SOLUTION TO YOUR PROBLEM:

import os
path=input("Please enter path: ")
dirs = os.listdir(path) #it will return list of names of files in given directory
noOffiles=int(0) #counting number of files
totalSize=int(0) #for calculation of total size of file
for file in dirs: #looping through dirs
print(file) #printing files in directory

for file in dirs:
   if os.path.isfile(file): #checking if given file name is existing file
       totalSize+=os.path.getsize(file)   #calculating file size and adding it in totalSize
       noOffiles+=1 #counting number of files

if(totalSize>1024): # as mentioned in reqirment if size is more than 1024 then convert it in kb
   inKB=totalSize/1024
   print("Total size: {0:.2f} KB".format(inKB))
else:
   print("Total size: "+str(totalSize)+" bytes");

avg=totalSize/noOffiles #calculation avg file size
if(avg>1024):
   inKB=avg/1024
   print("Average size of file: {0:.2f} KB".format(inKB))
else:
   print("Average size: "+str(avg)+" bytes");
