] | You cannot use [*keywords*](http://php.net/manual/en/reserved.keywords.php) as names for functions/classes/methods and constants, `do` is one. You can use them as variable names, however. | "do" is a keyword (can be used in a do while loop). Also you're echoing a function that returns nothing, but echoes something in it.
Rename the "do" function to "echoFunction" or whatever name you choose and then
change this:

```
import re
test_str = 'a,b.c/d,e,f.g/hij.k'
print(re.split(r'[,\/.]', test_str))

`r'[,\/.]'` means string of any of the three: `,`, `/` or `.`

```
['a', 'b', 'c', 'd', 'e', 'f', 'g', 'hij', 'k']
