Enhanced Table containing pivot results from calling table.pivot().

Instance Methods

__init__(self, parent, attr_val_path, attrlist)
PivotTable initializer - do not create these directly, use Table.pivot.

source code

__getitem__(self, val)
Provides direct indexed/sliced access to the Table's underlying list of objects.

source code

keys(self)

source code

items(self)

source code

values(self)

source code

pivot_key(self)
Return the set of attribute-value pairs that define the contents of this table within the original source table.

source code

pivot_key_str(self)
Return the pivot_key as a displayable string.

source code

has_subtables(self)
Return whether this table has further subtables.

source code

dump(self, out=sys.stdout, row_fn=<built-in function repr>, limit=-1, indent=0)
Dump out the contents of this table in a nested listing.

source code

dump_counts(self, out=sys.stdout, count_fn=<built-in function len>, colwidth=10)
Dump out the summary counts of entries in this pivot table as a tabular listing.

source code

summary_counts(self, fn=None, col=None, summarycolname=None)
Dump out the summary counts of this pivot table as a Table.
