pop vs remove python

"diffrence between 'remove()','pop()' and 'del list[]' functions"
# list.remove()
*It only removes the object it does not bother about indexing.
# list.pop()
* pop removes specific index,also it returns object back.
# del list[]
*it can remove the index and object in it also entire list can be deleted.
#definition of each of the list function concludes some diffrences in them.
*'remove' deals with object while 'pop' and 'del' do focus on index.
*'pop' could return the deleted value of index while 'del' can not.
#These functions are aplicable at list not sequence like tuple.

pop vs popitme python

pop(key[, default]):
If key is in the dictionary, remove it and return its value, else return default. If default is not given and key is not in the dictionary, a KeyError is raised.

popitem():
Remove and return a (key, value) pair from the dictionary. Pairs are returned in LIFO order.
popitem() is useful to destructively iterate over a dictionary, as often used in set algorithms. If the dictionary is empty, calling popitem() raises a KeyError.

Changed in version 3.7: LIFO order is now guaranteed. In prior versions, popitem() would return an arbitrary key/value pair.

python list safely pop

In [1]: from typing import List, Any

In [2]: x = [{"count": 100}, {"count": 30}]
# use this function
In [3]: def defaultable_pop(input_list: List, index: int, default_value: Any = None) -> Any:
   ...:     try:
   ...:         return input_list.pop(index)
   ...:     except IndexError:
   ...:         return default_value
   ...:
#								list, index, (default of empty dict)
In [4]: y: int = defaultable_pop(x, 0, dict({})).get("count", 0)

In [5]: y
Out[5]: 100

# As opposed to:
# y: int = x[0].get("count", 0) if len(x) > 0 else 0
