pandas.RangeIndex¶

class pandas.RangeIndex(start=None, stop=None, step=None, dtype=None, copy=False, name=None)[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), range, or other RangeIndex instance: If int and “stop” is not given, interpreted as “stop” instead.
stopint (default: 0)
stepint (default: 1)
dtypenp.int64: Unused, accepted for homogeneity with other index types.
copybool, default False: Unused, accepted for homogeneity with other index types.
nameobject, optional: Name to be stored in the index.

`stop`	The value of the stop parameter.
`step`	The value of the step parameter (`1` if this was not supplied).

Methods
