You don't need to iterate the array. Just:
>>> x = ['ala@ala.com', 'bala@bala.com']
>>> x
['ala@ala.com', 'bala@bala.com']
>>> x.remove('ala@ala.com')
>>> x
['bala@bala.com']
This will remove the first occurence that matches the string.
EDIT: After your edit, you still don't need to iterate over. Just do:
index = initial_list.index(item1)
del initial_list[index]
del other_list[index]

Using filter() and lambda would provide a neat and terse method of removing unwanted values:
newEmails = list(filter(lambda x : x != 'something@something.com', emails))
This does not modify emails. It creates the new list newEmails containing only elements for which the anonymous function returned True.

January 18, 2018Remove Array Items Meeting Condition?
Hi. The first suggestion I'd recommend is to replace your array with a List . This will cut down the time it'll take to populate your collection. It also gives an added bonus of the Remove() method. Which makes it so that you can remove items from the collection instead of recreating it with what you'd like to save. As for the filtering. Why not do all the required checks in one loop and save (for array) the item which passes. Or remove (for list) the item which doesn't pass. A generic example of possible ways of approaching it # Initializes a new list with an initial size of $AllFilesArray $FilesToKeepList = [System.Collections.Generic.List[PSCustomObject]]::new($FilesToKeepList.Count) foreach ($item in $AllFilesArray) { # If example if (($itemToKeep.Property2 -eq 'SomeValue') -or ($itemToKeep.Property3 -eq 'SomeOtherValue')) { $FilesToKeepList.Add($item) } # Switch example switch ($itemToKeep) { { $_.Property2 -eq 'SomeValue' } { $FilesToKeepList.Add($item) # Break exits the loop and goes to the next item in collection without doing any further checks break } { $_.Property3 -eq 'SomeOtherValue' } { $FilesToKeepList.Add($item) break } } } More on reddit.com

Hi, so I am writing a class for doing some methods on a list.
I already know how to add an element to the end of a list by using the append() method.
However if I want to remove an element from the end of a list, without returning the value, how would I go about that? I know the pop() method can remove an element from the end of a list but it then returns the value of that element. What kind of method can I include in my class that will remove an element from the end of the list?

How to remove element from an Array in Python
Then we use the list comprehension to extract the data we want to remove using the loop that will iterate every element of the array since it is an iterable object of Python. Using the not equals operator, we picked that particular element that we don’t want further in our array test and initialized all other elements in a fresh new object test2. Finally, we display the test2’s data using print(). ... All of these techniques can help in removing elements from an array.

Delete the List and its element:We have multiple functions for deleting the List’s element with different functionality. del function helps to delete the list variable from code.pop function helps to delete the individual element according to positioning of the list. Return the position value.remove function helps to delete the first occurrence of the number or string mentioned in its arguments.Clear function clear the all elements present in the list without delete its variable.#Program:>>> a=[1,2,3,4,5,"sahil"]>>> a.pop(0)# delete element at position 01>>> a[2, 3, 4, 5, 'sahil']>>> a.remove(2)# delete element 2 that present at 0 position>>> a[3, 4, 5, 'sahil']>>> del a[1:3] # delete multiple elements from list at position 1 to 2 >>> a[3, 'sahil']>>> a.clear()# clear the list>>> a[]>>> del a #delete the variable a>>> aTraceback (most recent call last): File "", line 1, in NameError: name 'a' is not definedIf you are interested in learning Python consider taking Data Science with Python Course.

You can use the pop() method to remove specific elements of a list.EXAMPLE:a=[1,2,3,4,5,5]a.pop(2)OUTPUT: 3pop() method takes the index value as a parameter and removes the element at the specified index. Therefore, a[2] contains 3 and pop() removes and returns the same as output. You can also use negative index values.EXAMPLE:a=[1,2,3,4,5,5]a.pop(-1)OUTPUT: 5Hope it helps!!If you need to know more about Python, It's recommended to join Python course today.Thanks!

Hey Guys,
when you're pop or remove to delete an element from a list, does python then resize the list in memory to account for the deleted item? Are all the items after the deleted items swapped one position back up? I'm a bit confused as to how the internal memory structure works for these dynamic arrays. Thanks guys.
