url = "http://localhost/TestFile.zip" # Specify Desired Url from
file_name = url.split('/')[-1]
u = urlopen(url)
f = open(file_name, 'wb')
meta = u.info()

bufferSize = 9192
count = fielSize = 0
while True:
buffer = u.read(bufferSize)
if not buffer:
break
fielSize += len(buffer)
f.write(buffer)
per = (fielSize * 100 / totalFileSize)
status = "[%3.2f%%]" % per + "." * (int)(per/2)
if count > 200:
count = 0
print (status)
else:
print (status, end="\r")
count += 1
f.close()

python print is used to display the output to a user. It will calculate how much file is downloaded and how much is remaining to download using buffer.
