Table· property

Table.columns

the list of column names, in order

Python

columns: list[str]

Returns list[str] — the column names, in order

Example#

Python

t.columns               # ['name', 'score']
"score" in t            # True — membership tests a column name
len(t)                  # row count

columns is a plain list[str], in schema order. To test whether a column exists, use name in table; for the full types use schema.
