Really...!!!! I just can't beleive it. I am running my scirpt on an
INTEL Core2duo CPU machine with 2GB of RAM. I've started it two hours
back, but still it is running. This is how my code looks like
def createFiles(path):
m.write(strftime("%Y-%m-%d %H:%M:%S") +" Creating files in the
folder "+path+"\n")
global c
global d
os.chdir (path)
k = 1
for k in range (1,1001):
p = "%.2d"%(k)
FName = "TextFile"+c+"_"+d+"_"+p+".txt"
l =1
for l in range(1 , 11):
os.system ("\"echo "+FName+" >> "+FName+"\"")
l = l +1
k = k+1
MainPath = "C:\\Many_50000_1KB"
try:
os.mkdir (MainPath)
m.write(strftime("%Y-%m-%d %H:%M:%S") +" Created the base directory
\n")
except:
m.write(strftime("%Y-%m-%d %H:%M:%S") +" base directory already
exists\n")
os.chdir (MainPath)
for i in range (1 , 6):
j = 1
c = "%.2d"%(i)
FolderName ="Folder"+c
try:
os.mkdir (FolderName)
m.write(strftime("%Y-%m-%d %H:%M:%S") +" Created the folder
"+FolderName+"\n")
except:
m.write(strftime("%Y-%m-%d %H:%M:%S") +" Folder "+FolderName+"
already exists \n")
os.chdir (FolderName)
path = os.getcwd ()
#createFiles(path)
for j in range ( 1 , 11):
d = "%.2d"%(j)
FolderName = "Folder"+c+"_"+d
try:
os.mkdir (FolderName)
m.write(strftime("%Y-%m-%d %H:%M:%S") +" Created the
folder "+FolderName+"\n")
except:
m.write(strftime("%Y-%m-%d %H:%M:%S") +" the folder
"+FolderName+" exists \n")
os.chdir (FolderName)
path = os.getcwd ()
createFiles(path)
os.chdir ("..")
j = j + 1
os.chdir ("..")
i = i + 1
Can you please let me know where do I have to modify it, to make it
faster.
Thank you,
