Show start value of trange as initial value

Currently if we use trange(a,b), it shows a progressbar starting from 0 with total b-a steps. But intuitively I expect a progressbar starting from a with total b steps. That is trange(a,b) should be equivalent to tqdm(initial=a, total=b). Does this make sense?

You can do trange(a, b, initial=a)...

[cmpute]

Oh cool, didn't think of that

[cmpute]

But actually it's equivalent to trange(a, b, initial=a, total=b)... Isn't this too redundant?

[casperdcl]

Arguably both inital and total are redundant in your use case, but I don't think they should be inferred from a and b by default.

If we auto-infer then everyone using trange(a, b) will also get a bar starting at a/(b-a)*100% complete which is not usually what people want

[cmpute]

Maybe add an option for auto-infer is great, like trange(a, b, infer_start=True)

trange(a, b, initial=a, total=b) is what I need. Thanks!

Where can I find the full parameters document?
