Then, sorted() sorts the pairs, and the key argument is applied with a function returning x[1]. This refers to the second item in the tuple, hence the value. So all items are sorted according to the value.And sorted() returns a list of tuples:...
Update an Existing Key/Value Pair Withupdate()Function in Python In the previous section, we discussed a method that updates an existingkey-valuepair and adds a newkey-valuepair to the dictionary if the key is not found. But, it works with only one key/value at a time. If we need to...
