Utility functions for processing tweets or texts
A few obligatory PEP-8 rules:


Imports should be grouped in the following order:


standard library imports
related third party imports
local application/library specific imports

Use blank lines in functions, sparingly, to indicate logical sections.
Two blank lines between the import statements and other code.
Two blank lines between each function.
Don't use spaces around the = sign when used to indicate a keyword argument or a default parameter value.


If this is written for python-3.x, I'd also suggest going for Type Hinting.



In the split_texts definition, I'd suggest having naive=False as the default (or naive=True) depending on the more obvious choice of the two.



In the function total_rts (could be renamed to total_retweets), you can avoid one entire level of nesting by returning early in the first if not string_inclusion clause.



The function clean_text makes several transition tables, which could be extracted out of the function and made a constant. More importantly, what I understood from the definition, I think you're (in order):


cleaning the text of all printable characters
cleaning the text of all characters leftover from step 1
cleaning all punctuation from result of step 2
replacing all kinds of whitespace characters with a single ' ' in the result of step 3.


You can define global transition tables as follows:

WHITESPACE = ' ' * len(string.whitespace)
CLEAN_TRANSLATION = str.maketrans(string.whitespace, WHITESPACE, string.punctuation)


Alternatively, you can take the CLEAN_TRANSLATION inside the clean_text function and use the undefined non-printable characters in concatenation to string.punctuation. So, the function becomes:

def clean_text(text):
    undefined_chars = text.translate(
        str.maketrans({c: None for c in string.printable}))
    cleanup_translation = str.maketrans(
        string.whitespace, WHITESPACE, string.punctuation + undefined_chars)
    return text.translate(cleanup_translation)




And, most importantly, the description for each function that you've provided in the question, could be converted to a docstring for each of them.
