This is a really simple question, but I didnt find the answer. How to call an element in an numpy array?
import numpy as np arr = np.array([[1,2,3,4,5],[6,7,8,9,10]]) print arr(0,0) The code above doesn't work.

You can access an array element by referring to its index number. The indexes in NumPy arrays start with 0, meaning that the first element has index 0, and the second has index 1 etc.
To refer to multiple elements of an array, use the colon ':' operator, which allows you to specify a range of elements using the form 'start:end'. The colon alone, without start or end values, specifies all the elements in that dimension.
We can access elements of an array using the index operator [] . All you need do in order to access a particular element is to call the array you created. Beside the array is the index [] operator, which will have the value of the particular element's index position from a given array.
To access an individual element of an array, use the name of the array name followed by the index of the element in square brackets. Array indices start at 0 and end at size-1: array_name[index]; accesses the index'th element of array_name starting at zero.
Just use square brackets instead:
print arr[1,1] If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
