Index of 2d array python
Index is the number that states the location number of a specific element in a memory location. Since it uses sequential memory therefore the index numbers are also continuous. It is quite evident to note that the array indexing starts at 0 and end at n-1 where n is the size of the array. Moving with this article on 2D arrays in Python. Select a copy of row at index 1 from 2D array and set all the elements in selected sub array to 100 Python # Select a copy of row at index 1 from 2D array row = nArr2D[1].copy() # Set all the elements in selected sub array to 100 row[:] = 100 Two-dimensional arrays: nested generators. You can use nested generators to create two-dimensional arrays, placing the generator of the list which is a string, inside the generator of all the strings.
