Ignore repeated separators Split on multiple separators at the same time Remove leading or trailing separators from the ends of your stringIf you need any of those features, you should look into regular expressions using Python's re module. Specifically, the re.split function may come in handy....

Here’s an example of using several different line separators: Python >>> "foo\nbar\r\nbaz\fqux\u2028quux".splitlines() ['foo', 'bar', 'baz', 'qux', 'quux'] If consecutive line boundary characters are present in the target string, then they’re assumed to delimit blank lines,...

It can run the echo and potentially the rm as entirely separate commands by adding semicolons, which act as command separators allowing what would usually be multiple lines of code to run on one line. Running these malicious commands would cause irreparable damage to the file system, and ...

In the previous example, we exposed a single function to the command line. Nowwe'll look at ways of exposing multiple functions to the command line. Version 1:fire.Fire() The simplest way to expose multiple commands is to write multiple functions, andthen call Fire. ...
