I can't get Python's executemany for sqlite3 to work properly

I was trying to use executemany to insert values into a database, but it just won't work for me. Here is a sample:

clist = []
clist.append("abc")
clist.append("def")
clist.append("ghi")
cursor.executemany("INSERT INTO myTable(data) values (?) ", clist)

This gives me the following error:

sqlite3.ProgrammingError: Incorrect number of bindings supplied. The current statement uses 1, and there are 3 supplied.

However, when I change the list, it works fine:

clist = ["a", "b"]
cursor.executemany("INSERT INTO myTable(data) values (?) ", clist)

It works as expected! I can see the data in the database. Why does the first list not work and second one does ?

(PS: This is just a sample and not the actual code. I made a small test case for simplicity).
