# f-strings formatting (Python 3.6+)
# ====================
# - Formatted string literals (i.e., f-strings) provide a way
# to embed expressions inside string literals, using a minimal
# syntax.
# - It works by adding a 'f' char at the begining of a string,
# and then a placeholder '{}' which can contain variables,
# functions, etc. to format the value.
# Cleaner and easier to write.
