Can you remove key:value pairs from a dictionary and if so, how?

Yes, key:value pairs can be removed from a dictionary. The different methods to remove key:value pairs are given below:

1. By using del command:
It is used to delete an item with the specified key name. The syntax for doing so is as given below:

del <dictionary>[<key>]

For example:

dict =	{'list': 'mutable', 'tuple': 'immutable', 'dictionary': 'mutable'} 
del dict["tuple"]
print(dict)

Output

{'list': 'mutable', 'dictionary': 'mutable'} 

2. By using pop() method:
This method removes and returns the dicitionary element associated to the passed key. It is used as per the syntax:

<dict>.pop(key, <value>)

For example:

dict =	{'list': 'mutable', 'tuple': 'immutable', 'dictionary': 'mutable'} 
dict.pop("tuple")
print(dict)

Output

{'list': 'mutable', 'dictionary': 'mutable'} 

3. popitem() method:
This method removes and returns the last inserted item in the dictionary. It is used as per the syntax:

<dict>.popitem()

For example:

dict =	{'list': 'mutable', 'tuple': 'immutable', 'dictionary': 'mutable'} 
dict.popitem()
print(dict)

Output

{'list': 'mutable', 'tuple': 'immutable'} 

Here, the last element of dict was 'dictionary': 'mutable' which gets removed by function popitem().
