The simplest form:

>>> na="Abc | def | ghi | jkl [gugu]"
>>> na_out = na.replace('def', '').replace(' | ', ' ').replace('  ', ' ').replace('[', '').replace(']', '').strip()
>>> na_out
'Abc ghi jkl gugu'
>>> 


Another form:

>>> na_out = ' '.join(na.split(' | ')).replace('[', '').replace(']', '').replace(' def', '')
>>> na_out
'Abc ghi jkl gugu'
>>> 


There is the regular expression approach as well as several other
alternatives.  I could list other (simpler, more advanced, etc.) alternatives,
but you can also play with Python by yourself.  If you have a more concrete
specification, send it to the group.
