Word inside brackets not working in python regular expression

Question

I am trying to get all the test case list from a file. Eg. void DTC_SetHighBitRate_001() .

re.findall("void S?[DS]TC_.+\(\)", testCaseFile)

But now, few test cases are modified like this,

void DTC_SetHighBitRate_001(void) 
void DTC_SetHighBitRate_001(Void)

I tried to use regular expression like this:

re.findall("void S?[DS]TC_.+\([vV]oid)*(\)", testCaseFile)

But this did not work. I want to allow ONLY 'void' or 'Void' inside the brackets. How can i do that?

EDIT: Sorry to mention that, even if 'void' is not present, it should allow.

1. Empty paranthesis - ()
2. void
3. Void

Answer 1

Let me give you an improved version :

re.findall("void S?[DS]TC_.+\([vV]oid\)", testCaseFile)

This will find only the occurrences with void (notice the * removed)

re.findall("void S?[DS]TC_.+\(([vV]oid)?\)", testCaseFile)

This will find all the cases: just empty parentheses and with void .

Answer 2

如果只想获得...（void）或...（Void）术语，请尝试此

re.findall("void S?[DS]TC_.+\([vV]oid]*\)", testCaseFile)
