#os.mkdir("hello")
os.chdir("hello")
#os.mkdir("hello1")
f=open("hello1.txt","w")
f.write("hello world")
f.close()
os.remove("hello1.txt")
#os.rmdir("hello1")
print(os.getcwd())
#print(os.listdir("c:"))
print(os.listdir())
location = 'd:/c/'
for file in os.listdir(location):
   # if file.endswith(".c"):
        print(os.path.join(location, file))



Assignment of os module:-

1)  WAP to count total folder in the computer, drive, max size folder, total image for the particular director, total video on the directory, total python program in the computer.
