string_tokenizer_count

Instructions

Create a file string_tokenizer_count.py that contains a function tokenizer_counter which takes in a string as a parameter and returns a dictionary of words and their count in the string.

• The function should remove any punctuation from the string and convert it to lowercase before counting the words.

• The function should return a dictionary of words and their count, sorted alphabetically by word.

Usage

Here is an example of how to use the function:

string = "This is a test sentence, with various words and 123 numbers!"
result = tokenizer_counter(string)
print(string)

And its output:

string = "This is a test sentence, with various words and 123 numbers!"
result = tokenizer_counter(string)

Hints

• The re module can be used to remove non-alphanumeric characters.

• The collections module can be used to count the words.

• The operator module can be used to sort the dictionary alphabetically by word.
