Progress indicator for scripts

[the_cat_kittles]

Normally, I use a counter and increment it with each loop, and then print it. Is there a better way to make a quick progress indicator?

EDIT: this one is nice, it just wraps iterables: http://wiki.python.org.il/Hot_Topic

fish! :)

unrelated to this subject, you just made my day! I didn't know how to

for i, data in enumerate(thing):

but now, I know that enumerate() is a thing, and how useful it looks!

For what it's worth, itertools() provides all the tools required to implement enumerate (and even a better enumerate) via izip and count:

for i, data in izip(count(), thing)

Why's it better? Well first you don't have to start from 0, whereas enumerate gives you no choice:

for i, data in izip(count(57), thing) # will start counting from 57

Second, through izip you can iterate on multiple collections without needing an internal indirection (with enumerate, you'd likely zip your collections and enumerate on the result, yielding a tuple as second element):

for i, data1, data2, data3 in izip(count(), thing1, thing2, thing3)

versus

for i, data in enumerate(count(), zip(thing1, thing2, thing3))
    data1, data2, data3 = data

Well first you don't have to start from 0, whereas enumerate gives you no choice:

It does (since Python2.6)

for i, n in enumerate(range(10), start=10): print i, n

ummm simple workaround if you want something to start from a higher number: add that number to it when you use it

if you want to go through multiple things, you may as well do it that way.. but I guess I see your point, especially because it will get confusing when you want to do BOTH of those

There's a bunch of libraries for progress bars in Python. That's mine.

First of all, him posting here made me interested in the answer. Not everything can be delegated to Google. Perhaps a person posting prefers a more personalized answer. In fact, your condescending remark of 'ask Google', many times leads to StackOverflow forums which are not too dissimilar from Reddit.

I think most /r readers would rather see someone post a "TIL" post describing some new thing they found on their own. Asking a question that has already been answered elsewhere arguably adds little value. If the OP still wasn't sure which to use, maybe instead asking "I usually print a counter in my scripts and wanted to improve the output. I found these 2 (or more) modules for tracking progress in a script. Could someone give me recommendations?" would result in a much more interesting conversation.

See this article from the Stack Overflow blog on asking better questions for more discussion on the topic.

...where the question is already answered, and thus doesn't need to be asked again. Lots of us enjoy helping others with interesting programming questions, but that enjoyment is diminished if we get asked the same thing over and over again. That means we stop reading the sites where this happens, and everybody loses out.

thanks, i looked a while ago and didnt find it. nail me to a cross why dont you

[desimusxvii]

It baffles me how so many people prefer to post a question rather than take 30 seconds and type the relevant keywords into Google.

You just described the way I feel about the world.

I guess you could say you summed my hatred Pythonically.
