Adding a different function to your operate is as simple as adding A different search phrase argument, whereas modifying the language to guidance that new attribute is way more cumbersome. Consider stream redirection or buffer flushing, such as.
Copied! Python has equally conditional statements and conditional expressions. The latter is evaluated to one price which can be assigned into a variable or handed to your function.
Note: Looping over traces within a textual content file preserves their own newline figures, which combined with the print() purpose’s default conduct will result in a redundant newline character:
