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 pop vs remove

my_list = ['p','r','o','b','l','e','m']
my_list.remove('p')

# Output: ['r', 'o', 'b', 'l', 'e', 'm']
print(my_list)

# Output: 'o'
print(my_list.pop(1))

# Output: ['r', 'b', 'l', 'e', 'm']
print(my_list)

# Output: 'm'
print(my_list.pop())

# Output: ['r', 'b', 'l', 'e']
print(my_list)

my_list.clear()

# Output: []
print(my_list)
