I've just tried it, creating the 50,000 text files took 17 seconds on
my not
very fast machine. Python is certainly not the bottleneck here.
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
You're creating 500000 processes, 500000 shells, just to call 'echo' (!)
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
with open(FName, "w") as f:
for i in range(10):
f.write(FName)
