I am able to create structured json in expected format but extra slashes coming in JSON records and also json records shows as a string object. Please elaborate the solution or let me know where is the missings? Also please let me know any other approach to achieve the expected result. Source: Python-3x..

I have a csv file called sample.csv that I have converted into a record, this record is set up with an string value and a integer value like so: [Name,10] [Name1,12] [Name2,14] I would like to be able to sort these records into descending order and then eventually print the names and scores of the ..

I am trying to learn NumPy basic concepts but unable to wrap my head around few things. I am following this NumPy documentation Scalars Python defines only one type of a particular data class (there is only one integer type, one floating-point type, etc.). This can be convenient in applications that donâ€™t need to be ..

I have multiple arrays of equal size, and I want to concatenate the values in each cell to produce an output array of the same size, but where each element is a list. How can I do this? Example. Input: a = [[1,2], [3,4]] b = [[5,6], [7,8]] Desired output: c = [[[1,5],[2,6]], [[3,7],[4,8]]] How ..

I’m trying to filter a Json array using Python based on multiple conditions. My Json is similar to this (no root name): { "id": "123455", "outter": { "inner": [ { "nox": "abc:6666", "code": "1329", } ], }, "topic": { "reference": "excel" }, "date1": "1990-07-28T03:52:44-04:00", "finalDate": "1990-07-28T03:52:44-04:00" } { "id": "123435", "outter": { "inner": [ { ..

If I place dcc.Graph elements hardcoded in the layout: app.layout = html.Div( html.Div([ dcc.Graph(id=’graph-hammer’), dcc.Graph(id=’graph-saw’), dcc.Interval(id=’interval-component’, interval=1000, n_intervals=0)])) I get my desired result of 2 graphs plotted without problems. But if I create a list of dcc.Graph elements using append: list_graphs = [] for t in tools: list_graphs.append(html.Div(dcc.Graph(id=’graph-‘ + t))) app.layout = html.Div( html.Div([ list_graphs, ..

I’ve been working on optimizing some Euclidean distance transform calculations for a program that I’m building. To preface, I have little formal training in computer science other than some MOOCs I’ve been taking. I’ve learned through empirical testing in Python that assigning values to individual variables and performing operations on them is faster than performing ..

I’m looking for a way to calculate the average absolute difference between neighboring elements in a NumPy array. Namely, given an array like [[1, 2, 3], [4, 5, 6], [7, 8, 9]] The value for the middle square will be 2.5 (aka (4+3+2+1+1+2+3+4)/8). I know with SciPy’s correlate2d you can compute the average difference, but, ..

I have 3 arrays of X values, Y values, and probabilities. I’m trying to do two things but they’re practically the same coding wise I imagine. I want to find all the X values that are the same, and add up the corresponding probabilities into another array. (So if my X values are [3,7,4,7] and ..

I am trying to convert an image into an array where, for example, if I have an image of 20×20 pixels I would like to have an array of 20 rows and 20 columns. I would like to have each unique colour to be represented by a number. So basically this code but with unique ..
