Here is my list of tuple:

[('Abbott', 'Texas'), ('Abernathy', 'Texas'), ('Abilene', 'Texas'), ('Ace', 'Texas'), ('Ackerly', 'Texas'), ('Alba', 'Texas'),('Addison', 'Texas'), ('Adkins', 'Texas'), ('Adrian', 'Texas'), ('Afton', 'Texas'), ('Agua Dulce', 'Texas'), ('Aiken', 'Texas'), ('Alamo', 'Texas'), ('Alanreed', 'Texas'), ('Albany', 'Texas')]

From the above tuple list i want to remove ('Alba', 'Texas')

I tried many ways doing it,but it is not giving me expected result.

I've tried

[x for x in listobj if any(y is not Alba for y in x)]

  • What exactly did you try? and what does "not giving me result properly" entail? what does it give you? – Sayse Sep 11 '17 at 09:47
  • Is it really that hard to employ a search engine with a "remove item from list in python" query? – timgeb Sep 11 '17 at 09:48
  • 1) What have you tried? 2) Does order matter? – cs95 Sep 11 '17 at 09:49
  • [x for x in listobj if any(y is not Alba for y in x)] i think this is not proper one – venkat Sep 11 '17 at 09:51

    @venkat It's certainly not proper. It won't even run. – cs95 Sep 11 '17 at 09:51

list_of_tuples.remove(('Alba', 'Texas'))

or

list_of_tuples.pop(list_of_tuples.index(('Alba', 'Texas')))

  • note -- removing items from a list while iterating over it can cause problems, as it can change the index of the remaining items in the list and can lead to unexpected behavior. One way to avoid this problem is to create a new list containing only the elements that you want to keep, rather than modifying the original list. – ZakS May 09 '23 at 09:54

Using Python's list comprehension should work nicely for you.

foo = [('Abbott', 'Texas'), ('Abernathy', 'Texas'), ('Abilene', 'Texas'), ('Ace', 'Texas'), ('Ackerly', 'Texas'), ('Alba', 'Texas'),('Addison', 'Texas'), ('Adkins', 'Texas'), ('Adrian', 'Texas'), ('Afton', 'Texas'), ('Agua Dulce', 'Texas'), ('Aiken', 'Texas'), ('Alamo', 'Texas'), ('Alanreed', 'Texas'), ('Albany', 'Texas')]
foo = [x for x in foo if x!= ("Alba", "Texas")]

You can remove it by value:

your_list.remove(('Alba', 'Texas'))

But keep in mind that it does not remove all occurrences of your element. If you want to remove all occurrences:

your_list = [x for x in your_list if x != 2]

Anyway, this question already answered so many times, and can be easily found - remove list element by value in Python.

If you want to remove a tuple by its first element:

tup = [('hi', 'bye'), ('one', 'two')]
tup_dict = dict(tup) # {'hi': 'bye', 'one': 'two'}
tup_dict.pop('hi')
tup = list(tuple(tup_dict.items()))

  • To fall back on a list of tuple as the first line input, the last line should include `list()` and read as: `tup = list(tuple(tup_dict.items()))` – JV conseil Jun 03 '20 at 17:16
