     28 [^6]: You may have noticed that the name of this file is "results_paragraphs_latex.txt" rather than "results_paragraphs.txt," and that's because LaTeX needs a little special treatment if you're going to use the percentage symbol. LaTeX uses the percentage symbol as a comment sign, meaning that anything after the symbol is ignored and left out of the document. You have to "escape" the percentage symbol with a slash, like this: `\%`. I have this simple bit of code that converts the normal text file into a LaTeX-friendly version:
     29 
     30     ```python
     31     # make a LaTeX-friendly version (escape the % symbols with \)
     32     # Read in the file
     33     with open(results_text_file, "r") as file:
     34         filedata = file.read()
     35     # Replace the target string
     36     filedata = filedata.replace("%", "\%")
     37     # Write the file
     38     text_file_latex = "results_paragraphs_latex.txt"
     39     with open(text_file_latex, "w") as file:
     40         file.write(filedata)
     41     ```

     43 [^7]: You may have noticed there are two datasets I'm pulling from for this, "data," which includes everything on the basis of _hospitalizations_, and "df," short for "dataframe," which is a subset of "data" that only includes each _patient_ once (rather than a new entry for every hospitalization), along with a few other alterations that allow me to do patient-wise calculations.
