There are other means of finding information than Google. Really.
1. A couple of years ago, I wrote a very complete list of symbol syntax uses in Python 3. You can get is at
https://xploro.googlecode.com/files/PySymbols.html Unfortunately, searching for 'python syntax symbols' does not show this on the first few pages.
2. The python docs have an index. While the Symbols page does not have most of the entries in the above doc, it does have '* in function calls' and '** in function calls'.
3. The meaning of * and ** in function calls is explained, surprise, in the reference manual section (5.3.4 for Py3) on function calls, which is in the chapter on expressions.
