I'm not quite sure what you're asking. This code results in all the tables on the page:

soup.fetch("table")

And this code results in all the links in table 2:

(Toggle Plain Text)

soup.fetch("table")[2].fetch("a")

Similarly, this code gets all the "td" tags in table 2:

(Toggle Plain Text)

soup.fetch("table")[2].fetch("td")

It might help to give you a quick run-through of object syntax. Take this following code:

(Toggle Plain Text)

chair.colour

This code refers to the "colour" property of the "chair" object.

(Toggle Plain Text)

chair.chopup()

This code calls the "chopup" method that belongs to the chair object. Thus, you can think of "." as meaning "belongs to". The "colour" property belongs to the chair object, as too does the "chopup" method. In programming lingo, they are members of the chair object.

Lets go back to BeautifulSoup:

(Toggle Plain Text)

links = soup.fetch("tables")[3].fetch("a")

It may be more obvious what this does if I expand it out a little:

(Toggle Plain Text)

all_tables = soup.fetch("tables")
table3 = all_tables[3]
links_in_table3 = table3.fetch("a")
