result = [(u'ABC', u'(Choose field)', u'ABCD', u'aa', u'A', u'A_100')]
I'm trying to remove '(Choose field)'
from the above list using the following syntax:
result.remove('(Choose field)')
# and
result.remove("'(Choose field)'")
But both things are not working fine and it ends up with this error
{ValueError}list.remove(x): x not in list
First of all, your list contains tuple which contains string. And tuple doesn't support remove
Just convert tuples as list and then use remove
>>> res = list(result[0])
['ABC', '(Choose field)', 'ABCD', 'aa', 'A', 'A_100']
>>> res.remove('(Choose field)')
['ABC', 'ABCD', 'aa', 'A', 'A_100']
You can convert the tuple inside the list to another list and remove the item from there. This should do the work:-
result = list(result[0])
result.remove(u'(Choose field)')
If you want to use indexing and specifically want to remove 'a'
and 'b'
from distinct list: values = ['a', 1, 2, 3, 'b']
- you can do this:
pop_list=['a','b']
[values.pop(values.index(p)) for p in pop_list if p in values]
above will remove 'a'
and 'b'
in place - to get :
print(values)
[1, 2, 3]
