python remove array element
You don't need to iterate the array. Just: >>> x = ['[email protected]', '[email protected]'] >>> x ['[email protected]', '[email protected]'] >>> x.remove('[email protected]') >>> x ['[email protected], @smci: Python list is array-based: to delete an item in the middle, you have to move all items on the right to remove the gap that is why it is O(n) in time operation. deque() provides efficient operations on both ends but it does not provide O(1) insert, import numpy as np a = np.array([1, 2, 3, 4, 5, 6, 7, 8, 9]) index = [2, 3, 6] new_a = np.delete(a, index) print(new_a) #Prints `[1, 2, 5, 6, 8, 9]`. Note that numpy.delete() returns a new array since array scalars are immutable, similar to strings in Py, You can also use remove usernames = ["Billy", "Bob", "Apple"] if "Billy" in usernames: usernames.remove("Billy") # usernames = ["Bob", "Apple"]., To remove an element's first occurrence in a list, simply use list.remove : >>> a = ['a', 'b', 'c', 'd'] >>> a.remove('b') >>> print a ['a', 'c', 'd']. Mind th, You need to use del in case you want to remove an item by index: >>> arr=[13,14,67,23,9] >>> del arr[2] >>> arr [13, 14, 23, 9]. Because remove just removes the first item with that value, or if it doesn't exist in the list,obj : slice, int or array of ints. Indicate which sub-arrays to remove. axis : int, optional.
