The following code: import numpy as p myarr=[[0,1],[0,6],[0,1],[0,6],[0,1],[0,6],[0,1],[0,6],[0,1],[0,6],[0,1],[0,6],[0,1],[0,6],[0,1],[0,6],[0,1],[0,6]]
Let say I have complete Image of Newspaper front page i want it make asp.net or winform application so user can slice this page and then link this page to another image...
I have a 2D numpy array, FilteredOutput, that has 2 columns and 10001 rows, though the number of rows is a variable.
Array ( [university] => 57 [iit] => 57 [jee] => 44 [application] => 28 [study] => 26 [college] => 23
practising some python, which is a pretty easy language to grab up. I have >>> L = [1,2,3,4] >>> L[1:1] = [1,2,3]
This is pretty simple but I\'d love a pretty, pythonic way of doing it. Basically, given a dictionary, return the subdictionary that contains only those keys that start with a certain string.
Can I ask what the difference is开发者_运维百科 between string object slice() and substr() in JavaScript?They have different signatures, .slice() is:
var nums = new[]{ 1, 2, 3, 4, 5, 6,开发者_StackOverflow社区 7}; var pairs= /* some linq magic here*/ ;
This seems simple (and is trivial to write a three-line loop for), b开发者_如何学Gout how can I use numpy slicing make a list of the index locations of the upper diagonal of a numpy array? I.e.
I want to slice a NumPy nxn array. I want to extract an arbitrary selection of m rows and columns of that array (i.e. without any pattern in the numbers of rows/columns), making it a new, mxm array. F
