Remove Elements From a NumPy Array Based on a Mask
This tutorial will discuss about unique ways to remove elements from a numpy array based on a mask. Suppose we have a numpy array of numbers, # create sample numpy array arr = np.array([20, 25, 15, 30, 22, 18]) Now we want to remove elements from this array based on a boolean array or a …
Remove First N Elements from a NumPy Array
This tutorial will discuss about unique ways to remove first n elements from a numpy array. Suppose we have an NumPy array of numbers. Like this, numbers = np.array([34, 35, 78, 61, 56, 35, 90, 35]) Now we want to remove first N elements from this array. For this we are going to use the …
Remove Last N Elements from a NumPy Array
This tutorial will discuss about unique ways to remove last n elements from a numpy array. Suppose we have an NumPy array of numbers. Like this, numbers = np.array([34, 35, 78, 61, 56, 35, 90, 35]) Now we want to remove last N elements from this array. For this we are going to use the …
Remove Every Nth Element From a NumPy Array
This tutorial will discuss about unique ways to remove every nth element from a numpy array. Suppose we have a numpy array of numbers, like this, numbers = np.array([34, 35, 78, 61, 56, 35, 90, 35]) We want to delete every 2nd element from this array. Advertisements For this we will create a boolean array …
Remove Elements from a NumPy Array in a specific order
This tutorial will discuss about unique ways to remove elements from a numpy array in a specific order. Suppose we have an NumPy Array containing city names. Like this, # create sample numpy array cityNames = np.array([ ‘New York’, ‘Los Angeles’, ‘Chicago’, ‘Houston’, ‘Phoenix’, ‘Philadelphia’]) now we want to delete the elements at index position …

Remove The Middle Element from a NumPy Array
This tutorial will discuss about unique ways to remove the middle element from a numpy array. Suppose we have a numpy array of strings. Like this, city_names = np.array([ ‘New York’, ‘Los Angeles’, ‘Chicago’, ‘Houston’, ‘Phoenix’, ‘Philadelphia’]) Now, we want to remove an element from the middle of this numpy array. Advertisements To remove an …
