Python - Access NumPy Array Item

Question

I am using Python for the first time in a long time and am slightly lost. I have a numPy array that looks like this when I print it..

I am trying to get the 5 item from the array and save it as 2 variables, x and y.

I have tried accessing it using...

print("Item 5" + numpy_array[5])

But that is giving me an error

typeError: ufunc 'add' did not contain a loop with signature matching types dtype('S21') dtype('S21') dtype('S21')

Suppose your array is stored in variable called numpy_array, just do. Since your subarrays contains 2 elements, it will unpack the values into x and y

x, y = numpy_array[5]
print (x, y)
# (210, 553)

These are other examples:

print("Item 5: " + str(numpy_array[5]) ) #=> Item 5: [210 553]

print("Item 5: ", numpy_array[5][0], numpy_array[5][1] ) #=> Item 5:  210 553

print("Item 5: ", numpy_array[5][0], "-" , numpy_array[5][1] ) #=> Item 5:  210 553

print (f"Item 5: {numpy_array[5][0]}, {numpy_array[5][1]}" ) #=> Item 5: 210, 553
