Everyone Gets THIS Wrong In Python At Least Once

Everyone gets this wrong in Python at least once. #python #code #programming

[Lol-iluc]

happened to me once , spent half an hour trying to find where the bug was

[xzex]

in most programing languages and specially in the python the rule is that the first argument is inclusive and the second one is exclusive.

Bro, you made my days! Keep uploading!

Start, Stop, Step. Have this memorize.

My maths lecturer would get absolutely peeved that you called 0 <= k <= n a positive range.

[hawaiihiker]

negative = range(-3, 1)
print(list(negative))

[humanrightsadvocate]

Why isn't the step implicitly -1 when the second argument is smaller than the first?

[ParkYongwooAmi]

It’s not direction. It’s number of step

[available]

Minor detail, 0 is not positive (nor negative)

how to print 15 to 0

I use:
a = 15
for I in range(15) :
print(a)
a -= 1

[abhishankpaul]

I always write (0, n, 1) even in the case of positive numbers

[DrDeuteron]

Map(operator.neg, reversed(range(0, 3))) ?

[kartikeyachoudhary]

Be on the safer side and always use step argument

[Pawlo]

I was thinking that (0, -3) will cause error

[XdekHckr]

but why it doesn't have -3 and 3? it doesn't make sense. Also 0 is not positive or negative

[niaei]

Range's first two arguments are lower boundary and higher boundary. So put the lower value first and higher value next. range(-3, 0)

[saturdaysequalsyouth]

Is there a channel like this but for C programming?

[transientaardvark]

so here is a question - is the '3 how many, or is it the limit. because if it is how many, then it should be 3 (positive) in both cases and if it is the limit then the last value should be +/- 3. There no other logical answer. So yet again, Python is broken.

The main thing beginners mess up is to learn python...

why are people coding in python again ?
