craftutils.wrap.dragons.Table.add_row(vals=
None, mask=None) Add a new row to the end of the table.
The
valsargument can be:- sequence (e.g. tuple or list)
Column values in the same order as table columns.
- mapping (e.g. dict)
Keys corresponding to column names. Missing values will be filled with np.zeros for the column dtype.
- None
All values filled with np.zeros for the column dtype.
This method requires that the Table object “owns” the underlying array data. In particular one cannot add a row to a Table that was initialized with copy=False from an existing array.
The
maskattribute should give (if desired) the mask for the values. The type of the mask should match that of the values, i.e. ifvalsis an iterable, thenmaskshould also be an iterable with the same length, and ifvalsis a mapping, thenmaskshould be a dictionary.Parameters¶
- valstuple, list, dict or None
Use the specified values in the new row
- masktuple, list, dict or None
Use the specified mask values in the new row
Examples¶
Create a table with three columns ‘a’, ‘b’ and ‘c’:
>>> t = Table([[1,2],[4,5],[7,8]], names=('a','b','c')) >>> print(t) a b c --- --- --- 1 4 7 2 5 8Adding a new row with entries ‘3’ in ‘a’, ‘6’ in ‘b’ and ‘9’ in ‘c’:
>>> t.add_row([3,6,9]) >>> print(t) a b c --- --- --- 1 4 7 2 5 8 3 6 9
