You now know how to use NumPy arange(). The function np.arange() is one of the fundamental NumPy routines often used to create instances of NumPy ndarray. It has four arguments: start: the first value of the array stop: where the array ends step: the increment or decrement dtype: the...
Example-1: Print the unique values of the one-dimensional array The following example shows the use of the unique() function to create an array with the unique values of a one-dimensional array. A one-dimensional array of 9 elements has been used as the unique() function’s argument value...

Use of reshape() function: You have to install the NumPy library before practicing the examples of this tutorial. Different uses of the reshape() function have shown in the part of this tutorial. Example-1: Convert one-dimensional array to two-dimensional array ...

(array([0,1]),array([2,1])) Copy If you observe closely,bis now atupleof numpy arrays. And each array is the location of a positive element. What does this mean? Whenever we provide just a condition, this function is actually equivalent tonp.asarray.nonzero(). ...
To use np.argsort in descending order in Python, first apply np.argsort to our array, and then either invert the result using array slicing ([::-1]) or negate the array before sorting. For inverting, sort the array using np.argsort and then reverse the resulting indices. For negating, ...
Python doesn’t have a built-in array data type, however, there are modules you can use to work with arrays. This article describes how to add to an array using the array and the NumPy modules. The array module is useful when you need to create an array of integers and floating-point...
np.zeros(3, dtype = int).dtype This code retrives the data type attribute from the resulting NumPy array. To be precise, the data type isint64: dtype('int64') This is just one example. Python and NumPy supporta couple dozen different datatypes, so you can use this technique to create...
