python regular expression to divide a string

I need to split a string like this:

{tab 3}1/*{tab}*/30116{tab}2012{tab, 2}01{tab}{2016}enter

I want to separate the parts that are in and out of { and }

The idea is to make a text interpreter for commands to be passed to python pyautogui.

The result should be in order, perhaps a list with commands and strings.

[ 'tab, 3', '130116', 'tab', '2012', 'tab, 2', '01', 'tab', '2016', 'enter']

The order is important. Using Regex Tester I do this pattern:

re.compile (ur '(\{(|.)*\})', re.MULTILINE | re.IGNORECASE)

This marks all parts between { and }. But I'm not knowing how to extract or split the string.

The part between /* and */ I am already removing correctly before getting this part. They can ignore it.

If possible, I would like a Pythonic way to solve this. I'm starting in python, for this, I must have skipped the solution.

If there are any mistakes, forgive me. I'm from Brazil.

If there some other interpreter already, please show me.

Thanks in advance.

Solution

  • I understand comments will be filtered out already so I'm proposing a simple solution, not sure it's the most "pythonic" but pythonic enough and easy to get a hold of.

    You can use re.split according to {} chars and then remove the empty strings with a call to filter out the empty strings.

    import re

r="{tab 3}130116{tab}2012{tab, 2}01{tab}{2016}enter"

z = filter(lambda x : x!="",re.split("[{}]",r))

print(z)

    output:

    ['tab 3', '130116', 'tab', '2012', 'tab, 2', '01', 'tab', '2016', 'enter']

    (there may be other ways of doing it without the filter part with regex, more complex)
