pandas.RangeIndex

class pandas.RangeIndex[source]

Immutable Index implementing a monotonic integer range.

RangeIndex is a memory-saving special case of Int64Index limited to representing monotonic ranges. Using RangeIndex may in some instances improve computing speed.

This is the default index type used by DataFrame and Series when no explicit index is provided by the user.

Parameters
startint (default: 0), or other RangeIndex instance

If int and “stop” is not given, interpreted as “stop” instead.

stopint (default: 0)
stepint (default: 1)
nameobject, optional

Name to be stored in the index

copybool, default False

Unused, accepted for homogeneity with other index types.
