Lets say you have an multidimensional array a = np.array([[1, 2], [3, 5], [4,5], [9,5]]) I want all the possible combinations of two arrays given the multidimensional array "a" so that: [[1, 2],[3, 5]] , [[1, 2],[4,5]] … I have no idea how to due this. Does someone have some suggestions and tips? >Solution :… Read More Make all possible combinations of arrays
I need to do a regex using python and SQL respectively. If I have 3 strings like: aaa bbb 1234 cc d e ff fji1223 345 aaa bbb feij sdkj 434343 458iui3 48 aaa bbb 1234 fjie skfj The above are three strings. I want to delete the combinations of numbers and letters, or just… Read More How to use python and SQL to delete the combination of numbers and letters at the end but keep the numbers in other place?
right now I have a code that shows all the possible outcomes with 3 food items only thing is that I want it to do it with a budget that I give with readline it needs to display something like this • 6 worsten, 100 hamburgers, 75 frikandellen • 6 worsten, 160 hamburgers, 25 frikandellen… Read More showing all possible options with a budget for food items in php

from itertools import permutations,product,combinations_with_replacement colours = [‘r’,’g’,’b’] y = list(product(colours,repeat =2 )) x = list(combinations_with_replacement(colours,2)) print(y) print(x) I understand permutation of a set of objects is an ordering of those objects. When some of those objects are identical, the situation is transformed into permutations with repetition. >Solution : This may provide some insight: colours =… Read More What is the relationship between the product function and the concept of permutations with repetitions?
A list of variables with assigned values. I want to return all the possible combinations from each pair (every two of them). The print-out is the names of the pair, and sum of them. For example: (Mike, Kate) 7 I’ve tried below. The result comes out, but not the names of pairs: import itertools Mike… Read More Output variable names when summing a tuple
Let’s say we have four columns: Column1, Column2, Column3, ind import pandas as pd tbl = { ‘Column1’:[‘Spark’,10000,’Python’,’35days’], ‘Column2′ :[500,’PySpark’,22000,30000], ‘Column3′:[’30days’,’40days’,’35days’,’pandas’], ‘ind’:[1,2,1,3] } df = pd.DataFrame(tbl) Does anyone know is there a way to add a new column without loop that will gather values from first 3 columns based on index stored in ‘ind’ column?… Read More Pick a column value based on column index stored in another column (Pandas)
I have the following data: ID Site 2 NULL 2 32 3 6 4 7 8 12 8 13 9 14 9 14 Result should be: ID Site 2 NULL 2 32 8 12 8 13 Note that the result find unique combinations of ID and Site that repeat more than once for a given… Read More Return distinct results that appear more than once
I have an object: { a: 1, b: "2", c: "3", // … } I want to get an array with all possible combinations, as objects, of each key/value pair like this: [ { a: 1 }, { b: "2" }, { c: "3" }, { a: 1, b: "2", c: "3" }, { a:… Read More How can I get an array of all possible combinations of an object's key/values
I would like to create a python function, that can take in letters and output a pairwise comparison of the letter given. So for example, if my function is named pairwise_letters(), then it should behave as follows: >>> pairwise_letters(‘AB’) AB >>> pairwise_letters(‘ABC’) AB BC AC >>> pairwise_letters(‘ABCD’) AB BC CD AC BD AD >>> pairwise_letters(‘ABCDE’)… Read More function to output pairwise of passed letters
