(adsbygoogle = window.adsbygoogle || []).push({}); Hi. So I've been trying to teach myself some python basics because I will be taking a class where I need to know some python beforehand....

and I keep coming across range, arange, and xrange but I haven't really noticed what the difference is between these. It seems they do the same thing?

So can someone explain to me the differences between them and why I would want to use one over another and in what circumstances?


Thank you!

The range function returns a list of numbers between the two arguments (or one) you pass it.

For example, range(2) would return -> [0, 1]
range(0, 2) would return -> [0, 1] also

The xrange function is the same but returns an object. The benefit in this is much less memory used.

For example, xrange(2) would return -> xrange object
list(xrange(2)) would return -> [0, 1]

If you use both in a for loop, the result would be the same, except xrange would use less memory.

I would not worry about arange, it is used in numpy and returns an array instead of a list. It is pretty much a range function.

uhhh wutttttt
