To remove the first occurrence of an element, use list.remove:
>>> xs = ['a', 'b', 'c', 'd']
>>> xs.remove('b')
>>> print(xs)
['a', 'c', 'd']
To remove all occurrences of an element, use a list comprehension:
>>> xs = ['a', 'b', 'c', 'd', 'b', 'b', 'b', 'b']
>>> xs = [x for x in xs if x != 'b']
>>> print(xs)
['a', 'c', 'd']

July 25, 2023how can I remove rows from a numpy array based on a condition
You can use Boolean arrays as index masks. Say you have: >>> import numpy as np >>> M = np.array([[1,2], [3,4],[5,6]]); a = np.array([1, 3]) >>> M == a array([[ True, False], [False, False], [False, False]]) Because of the Numpy's broadcasting rules, a is compared with each row of M. We can apply some sort of reduction to each row: >>> (M == a).any(axis=1) array([ True, False, False]) In your case, you want to remove rows that match this condition, which means you want to keep rows that match the complementary condition, so one of these: >>> ~(M == a).any(axis=1) array([False, True, True]) >>> (M != a).all(axis=1) array([False, True, True]) And you can use that as an index: >>> M[(M != a).all(axis=1)] array([[3, 4], [5, 6]]) More on reddit.com

Usually Python will throw an Exception if you tell it to do something it can't so you'll have to do either:
if c in a:
a.remove(c)
or:
try:
a.remove(c)
except ValueError:
pass
An Exception isn't necessarily a bad thing as long as it's one you're expecting and handle properly.

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.
