python - numpy-equivalent of list.pop? - Stack Overflow
Is there a numpy method which is equivalent to the builtin pop for python lists? Popping obviously doesn't work on numpy arrays, and I want to avoid a list conversion. More on stackoverflow.com
Does pop(i) have a Time Complexity of O(n) or O(k)?
O(k) when k = n-1 is really the same as O(n) where time complexity is concerned. More on reddit.com

July 1, 2020list.pop and list.pop()
Python can't know this is a mistake. list.pop on its own is perfectly valid syntax. This gives you access to the pop method itself, which you might want for any number of reasons, such as passing it as a callback to another function. Now, a good linter will certainly see that you didn't do anything with that reference, and show a warning on that basis. But by itself this is not an error. More on reddit.com

June 27, 2024AttributeError: 'numpy.ndarray' object has no attribute 'pop'
Well, NumPy arrays do not have a .pop() method; those are on regular Python lists instead. You seem to use this for omitting grades less than 5. Maybe NumPy's boolean indexing could work here, e.g. marks = np.array([ [8.0, 9.0, 10.0], [4.0, 9.0, 8.0], [8.0, 3.0, 8.0], [10.0, 9.0, 5.0], [9.0, 9.0, 4.0] ]) omitted_5 = np.array([ row[~(row < 5)] # Keep those that are NOT less than 5 for row in marks ]) # array([array([ 8., 9., 10. ]), # array([ 9., 8. ]), # array([ 8., 8. ]), # array([ 10., 9., 5. ]), # array([ 9., 9. ])], # dtype=object) However, this results in an irregularly shaped data, which interferes with the GPA computation with credits. QUESTION: How would marks with omitted values behave with the GPA computation? For example, the last set of marks [9.0, 9.0, 4.0] which will essentially be filtered into [9.0, 9.0] Will it only get multiplied to [2, 2]? (Filtered credits values) Or should it instead be filtered into [9.0, 9.0, 0.0] and fully multiplied with [2, 2, 1]? (Unfiltered credits) More on reddit.com

There is no pop method for NumPy arrays, but you could just use basic slicing (which would be efficient since it returns a view, not a copy):
In [104]: y = np.arange(5); y
Out[105]: array([0, 1, 2, 3, 4])
In [106]: last, y = y[-1], y[:-1]
In [107]: last, y
Out[107]: (4, array([0, 1, 2, 3]))
If there were a pop method it would return the last value in y and modify y.
Above,
last, y = y[-1], y[:-1]
assigns the last value to the variable last and modifies y.

Here is one example using numpy.delete():
import numpy as np
arr = np.array([[1,2,3,4], [5,6,7,8], [9,10,11,12]])
print(arr)
# array([[ 1, 2, 3, 4],
# [ 5, 6, 7, 8],
# [ 9, 10, 11, 12]])
arr = np.delete(arr, 1, 0)
print(arr)
# array([[ 1, 2, 3, 4],
# [ 9, 10, 11, 12]])

r/learnpython on Reddit: Does pop(i) have a Time Complexity of O(n) or O(k)?
July 1, 2020 -
I'm reading a book on data structures and algorithms in python and the say pop(i) is O(n) but on Python's website it states that pop intermediate is O(k)? See here: https://wiki.python.org/moin/TimeComplexity
To me it makes sense that it would be O(k) since you only have to shift the objects to the right of the index that you popped but please correct me if I'm misunderstanding something.

O(k) when k = n-1 is really the same as O(n) where time complexity is concerned.

The time complexity depends not on n, but on the index value to list.pop(), which is possibly a function of n, or not. For example, as n grows, any fixed negative index value to list.pop() will be O(1), and any fixed non-negative value will be O(n). So 'k' captures the idea that the time-complexity is "parameterized" not by n, but some other variable.

The pop() method is a mutating method. It changes the length and the content of this. In case you want the value of this to be the same, but return a new array with the last element removed, you can use arr.slice(0, -1) instead.

r/learnpython on Reddit: list.pop and list.pop()
June 27, 2024 -
This feels like one of those python weird things. I am interested in explanations.
If I have a list=[1,2,3,4] and I do list.pop() the result is list=[1,2,3].
Perfect, just what I wanted.
However, if I am not careful and instead do list.pop--note there are no parentheses this time--I get no syntax error or warning and nothing happens, leading me to a strange debug session.
In the repl, if I do l.pop it just identifies it as a built-in method of list object at 0xwhatever. That's useful, but why is there not at least a runtime warning when I make this mistake in my code?

mylist = [1,2,3,4] popper = mylist.pop popper() print(mylist) >>>[1,2,3] Popper is a function definition. Like below. def myFunc(): pass aliasFunc = myFunc This is all valid Python and can be useful in certain situations. (Function selectors, partials) Thus no run time errors until you need it to be a list. To the compiler there isn’t a mistake being made, until then.
