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]']
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 != '[email protected]', emails))
This does not modify emails. It creates the new list newEmails containing only elements for which the anonymous function returned True.

How do I remove elements from a 1D array?
For the record, if you re-run your program, you'll get a different 2D array each time since you did not set a seed. I've set a seed that fullfills this condition: np.random.seed(42) x1 = np.random.randint(10, size=(4, 6)) second_col = x1[:, 1] filtered_col = second_col[second_col != 6] print(filtered_col) In numpy you can index using boolean expressions like second_col != 6. This creates an index vector of Trues and Falses. This index vector is then applied to your target, retaining only values at the positions where the index vector is True. 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.

You invoke the .pop() method on the books list with an index of 0, indicating the first element in the list. This call removes the first title, Dragonsbane, from the list and then returns it.

Use del and specify the index of the element you want to delete:
>>> a = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> del a[-1]
>>> a
[0, 1, 2, 3, 4, 5, 6, 7, 8]
Also supports slices:
>>> del a[2:4]
>>> a
[0, 1, 4, 5, 6, 7, 8, 9]

You probably want pop:
a = ['a', 'b', 'c', 'd']
a.pop(1)
# now a is ['a', 'c', 'd']
By default, pop without any arguments removes the last item:
a = ['a', 'b', 'c', 'd']
a.pop()
# now a is ['a', 'b', 'c']
