#### Putting the loop inside of loop properly

```I just would like to make my previous question simpler and I bit adjusted m=
y code with help with Ulich and Chris.
The basic structure of my code is:

for c in range(5,25):

for columns in ( raw.strip().split() for raw in f ):
a.append(columns[c])
x =3D np.array(a, float)
not_nan =3D np.logical_not(np.isnan(x))
indices =3D np.arange(len(x))
interp =3D interp1d(indices[not_nan], x[not_nan], kind =3D 'nearest=
')
p =3D interp(indices)

N =3D len(p)

fpsd =3D plot_freq*PSD
f.seek(0,0)
for d in range(336):

y =3D fpsd[d]
y1 =3D y1 + [y]
m =3D np.mean(y1)
m1 =3D m1 + [m]
------------------------------------------------------------------
I just removed seemingly unnecesary lines. I expect that last loop can prod=
uce the each order values (first, second,.... last(336th)) of fpsd from for=
mer loop.
fpsd would be 20 lists. So, fpsd[0] in third loop shoul be first values fro=
m 20 lists and it expects to be accumulated to y1. So, y1 should be the lis=
t of first values from 20 fpsd lists. and m is mean of y1. I expect to repe=
at 356 times and accumulated to m1. However, it doesn't work and fpsd value=
s in and out of the last loop are totally different.
My question is clear?
Any help or questions would be really appreciated.
Isaac
```

When you're using .split() with no argument (split on any whitespace),
you don't need to use .strip() with no argument (strip any whitespace):

>>> ' foo  bar  '.strip().split()
['foo', 'bar']
>>> ' foo  bar  '.split()
['foo', 'bar']

while loop inside a for loop
Hi, can someone please tell me why "time" (t) is not updated correctly within the while loop? Please run this small code in your machine and you'll know what I'm taking about. What I want is: for t=1 run the "while loop" until iq<=(numberc-1) then t=2 run the "while loop" again until iq<=(numberc-1), and so on. Basically, this code runs through all the nonzero elements of A and attempts to divide them individually into two, once a certain time has passed. Please feel free to ask for clarifications. Many thanks in advance. A=[0 0 0 0 0 0 ...

LOOP and +LOOP
With LOOP, since the index (I) increases by 1 with each loop iteration, we can test for equality as a means to determine if it's time to exit the loop or not: : TEST 10 0 DO I . LOOP ; TEST 0 1 2 3 4 5 6 7 8 9 Here, when I gets to 10, the loop exits. It's not so easy with +LOOP, since the index can be changed by any arbitrary value on each iteration: : TEST 100 0 DO I . RANDOM +LOOP ; Here, we cannot test for equality. We have to test for crossing a boundary instead, at least as far as I can see. With that in mind, are these following results correct: : TEST 10 0 DO I . 1 +LOOP ...

Ending a while loop inside a while loop
How do I make a while loop run as long as the while loop that contains it is running? I tried wiring both conditional terminals to a stop button in the outer loop, but that doesnt seem to work? Is there another way? &nbsp; Thanks. It doesn't work because of data dependency. Once you are inside the inner loop the outer loop will not go to the next iteration until the inner loop is done. It sounds to me like you want parallel loops running, rather than one inside the other. If you open the Example Finder (Help -&gt; Find Examples), and search for "loops", open the examples...

Re: i am having a problem with while loops, i have two while loops, i have a random number generator inside the &quot;inside&quot; loop and i want to read an array outside the &quot;outer&quot;
I think I have a similar problem - I have a while loop with Flat Sequence controlled for loop that produces output. This output needs to be displayed every while loop pass, but I get no output as the while loop feeds back thru a shift register and repeats all the innner funcions without sending the ouput to form new entries in the array. &nbsp; Is there any way we could stop the while loop for a split second (but practically just for no time, so that no time is wasted when it outputs the data)? &nbsp; Or is it a bad approach altogether? &nbsp; Appreciate any advice. &nbsp; kolo...

speed up for loop inside for loop short question
Hi there, Given three column vectors x,y,z I want to calculate the probabilities: P(X<Y<Z), P(X=Y<Z), P(X<Y=Z), P(X=Y=Z). The following code gets the job done but I would like it to be faster. Is there a way of getting rid of at least one of the for loops? (I described the problem above instead of just giving the code because it might be helpful for someone to take a completely different approach, or check me (I think this is correct). Anyway if you are bored to check, any ideas regarding the speed would be more than welcome!). Thanx in advance for any answers! o...
