Percent groovy list slicing - groovy

my code:
def originalList = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100]
def newList = orginalList.percent(0.05,0.95) //I have no idea what I'm doing here
println newList
I have an original list of numbers, they are 1 - 100 and i want to make a new list from the original list however the new list must only have data that belongs to the sub-range 5%- 95% of the original list
so the new list must be like [5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18....95]. How do i do that? i know my newList code is wrong


You mean like:
originalList[ 4..94 ] // zero starting pos
Or do you need percentages?
You could do:
originalList[ (originalList.size() * 0.05 - 1)..<(originalList.size() * 0.95) ]
You could also use the metaClass:
List.metaClass.percent { double lower, double upper ->
int d = lower * delegate.size() - 1
int t = upper * delegate.size()
delegate.take( t ).drop( d )
}
originalList.percent( 0.05, 0.95 )

How to divide data in excel into 4 columns whose sum is almost equal to 1/4 of the sum of all values/

I have this set of numbers.
74, 15, 60, 5, 61, 56, 4, 23, 47, 66, 20, 54, 39, 9, 34, 37, 45, 93, 85, 79, 4, 76, 85, 51, 78, 60, 95, 50, 79, 62, 21, 75, 18, 5, 79, 46, 76, 92, 11, 100, 51, 39, 80, 92, 95, 20, 62, 1, 22, 69, 65, 45, 34, 42, 40, 8, 29, 82, 38, 9, 100, 78, 22, 11, 57, 71, 38, 35, 37, 32, 19, 58, 91, 90, 91, 26, 38, 85, 96, 3, 80, 18, 32, 74, 97, 60, 65, 85, 92, 38, 12, 31, 37, 76, 84, 9, 17, 33, 20, 19
I would like to divide this set of numbers into 4 parts/columns in excel so that their sum is as close as possible to 1/4 of the value of all numbers

Total of all numbers is 5049. 1/4 equals 1262.25 .
Is the sort of thing you're after?
All those numbers, sorted numerically, then added to columns, the totals almost matching to a quarter of the total...

I have a list of integers that is called numbers in this code Print every number that is greater than 90 in python?

Here's my code :
numbers = [76, 83, 16, 69, 52, 78, 10, 77, 45, 52, 32, 17, 58, 54, 79, 72, 55, 50, 81, 74, 45, 33, 38, 10, 40, 44, 70, 81, 79, 28, 83, 41, 14, 16, 27, 38, 20, 84, 24, 50, 59, 71, 1, 13, 56, 91, 29, 54, 65, 23, 60, 57, 13, 39, 58, 94, 94, 42, 46, 58, 59, 29, 69, 60, 83, 9, 83, 5, 64, 70, 55, 89, 67, 89, 70, 8, 90, 17, 48, 17, 94, 18, 98, 72, 96, 26, 13, 7, 58, 67, 38, 48, 43, 98, 65, 8, 74, 44, 92]
while numbers>=90:
print(numbers)
Here the Output :
Traceback (most recent call last): File "main.py", line 3, in while numbers>=90: TypeError: '>=' not supported between instances of 'list' and 'int'

numbers = [76, 83, 16, 69, 52, 78, 10, 77, 45, 52, 32, 17, 58, 54, 79, 72, 55, 50, 81, 74, 45, 33, 38, 10, 40, 44, 70, 81, 79, 28, 83, 41, 14, 16, 27, 38, 20, 84, 24, 50, 59, 71, 1, 13, 56, 91, 29, 54, 65, 23, 60, 57, 13, 39, 58, 94, 94, 42, 46, 58, 59, 29, 69, 60, 83, 9, 83, 5, 64, 70, 55, 89, 67, 89, 70, 8, 90, 17, 48, 17, 94, 18, 98, 72, 96, 26, 13, 7, 58, 67, 38, 48, 43, 98, 65, 8, 74, 44, 92]

Generate 2 random integer list of different size

I am trying to generate 2 list with different size consisting with random numbers. I can generate 2 list with random numbers, but how to achieve 2 different length of lists?
import random
list1 = random.sample(xrange(100), 10)
list2 = random.sample(xrange(100), 10)
print(list1)
print(list2)
Need to generate the lists with 2 random different sizes as well, as if both the lists are completely random.

Try the below code. Hope this would help.
If you want to create random number list of two different sizes. Then you can explicitly, pass the size of the list as a second argument, as given below.
import random
list1 = random.sample(xrange(100), 100)
list2 = random.sample(xrange(100), 10)
print(list1)
print(list2)
Ouput will be :
[46, 73, 13, 89, 44, 23, 74, 8, 19, 79, 36, 80, 85, 42, 82, 39, 61, 15, 27, 68, 67, 30, 11, 21, 86, 16, 63, 95, 17, 90, 37, 81, 20, 71, 93, 99, 40, 6, 47, 92, 58, 35, 12, 2, 10, 98, 87, 50, 51, 97, 70, 65, 78, 22, 72, 45, 59, 0, 52, 14, 1, 84, 43, 24, 54, 31, 18, 69, 7, 75, 53, 25, 57, 94, 83, 66, 3, 5, 88, 32, 4, 28, 29, 55, 9, 77, 60, 62, 41, 76, 48, 56, 34, 91, 33, 96, 49, 38, 26, 64]
[82, 58, 74, 61, 21, 77, 53, 35, 44, 59]
Now if you want to randomly decide the size of the list, the pass a random number as a second argument, by using randint function
import random
list1 = random.sample(range(100), random.randint(1,101))
list2 = random.sample(range(100), random.randint(1,101))
print(list1)
print(list2)
Output would be:
[93, 60, 82, 53, 16, 42, 0, 68, 88, 11, 89, 62, 38, 14, 27, 8, 45, 25, 83, 97, 94]
[30, 5, 19, 11, 14, 6, 7, 86, 16, 53, 71, 12, 90, 32]

You can try something like this, which would randomly generate the size between 1 and 10.
import random
list1 = random.sample(range(100), random.randint(1,10))
list2 = random.sample(range(100), random.randint(1,10))
print(list1)
print(list2)
This will generate random length of the lists. Hope it helps !

You need to randomize the second Parameter as well to become lists of random size:
import random
list1 = random.sample(range(100), random.randint(1,10))
list2 = random.sample(range(100), random.randint(1,10))
print(list1)
print(list2)

Identifying edges in a connected component - Python

I have a set of connected components obtained from a tree Tas follows.
To get all the connected components, I'm using the following code sample:
connectedcomponents = sorted(nx.connected_components(T), key = len,reverse=True)
This is what I'm getting;
[{66, 98, 68, 37, 7, 8, 73, 75, 44, 47, 81, 51, 19, 23, 55, 56, 58, 62, 63}, {97, 3, 6, 71, 39, 11, 77, 17, 60, 95}, {99, 5, 10, 43, 15, 20, 90, 92, 93}, {96, 4, 76, 80, 84, 53, 52}, {34, 74, 46, 18, 24, 61, 30}, {36, 9, 41, 83, 88, 57}, {65, 69, 40, 78, 21, 54}, {1, 2, 12, 13}, {89, 26, 70, 31}, {0, 42, 28, 79}, {32, 85, 86}, {59, 45, 94}, {82, 50, 22}, {64, 72}, {33, 14}, {16}, {87}, {48}, {91}, {49}, {67}, {29}, {35}, {25}, {38}, {27}]
I need to get the edges in each of these components. For an example, for the first component {66, 98, 68, 37, 7, 8, 73, 75, 44, 47, 81, 51, 19, 23, 55, 56, 58, 62, 63} I need a separate list of edges as [(37,47),(47,7),(7,62),...].
I tried it as follows:
def nodes_connected(u, v):
if u in T.neighbors(v):
return True
else:
return False
for i in connectedcomponents:
print(i)
for u,v in i:
nodes_connected("u", "v")
edges.append((u,v))
But didn't work!!!
Can someone please help me with this?

I've had to guess at where the line breaks fall in your data but I think I have it right.
The repeated data is because you are initializing list3 in the wrong place. It should be after if line.startswith('ALLOWED_VLAN'):
With that fix, your program does this:
interface port-channel
[2, 27, 4, 5, 6, 30, 38, 41, 48, 49]
[74, 678, 1101, 1201]
interface port-channel
[37, 2001, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 75, 1051]
interface port-channel
[10, 37, 39, 18, 51, 75, 901]
[3204, 3305, 2901]
which is close to what you want. You just need to combine the lists of integers before printing them. Combine the values of vnlanallowed in the if part of the loop, then print it out and reinitialize it in the elif part.
To get the exact format of the output you want, you need to wait until you know you have all of the lists of port-channel numbers before printing them. You only know that when you see a new list start, or you reach end-of-file.
