I tried just

1) foo;
2) bar;

in LaTeX, but I found it looks strange.

You can use the enumitem package to make all kinds of lists.

Example:

documentclassarticle

usepackageenumitem

begindocument
beginenumerate[noitemsep,label=arabic*)]
 item foo
 item bar
endenumerate
enddocument

The key part for your question is the label=arabic*). The arabic part tells LaTeX you want numbers, the ) says you want brakets. The * is also necessary.

The noitemsep isn't necessary, I just like using it whenever I make lists, as I dislike spaces placed between items (which is the default).

Check out the documentation for this package if you want to learn more about it

Are you talking about an enumeration?

With the enumitem package and its shortlabels option, we have this:

documentclassarticle
usepackage[shortlabels]enumitem
begindocument
 beginenumerate[1)]
 item foo;
 item bar;
 endenumerate
enddocument

The enumerate package manages shortlabels natively:

documentclassarticle
usepackageenumerate
begindocument
 beginenumerate[1)]
 item foo;
 item bar;
 endenumerate
enddocument
