Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Define a getcases function that returns a series for total_cases_pm for the countries of a region."

A block of code is set as follows:
