Alias for int_range().

Parameters:

start: Lower bound of the range (inclusive).
end: Upper bound of the range (exclusive).
step: Step size of the range.
dtype: Data type of the range. Defaults to Int64.
eager: Evaluate immediately and return a Series. If set to False (default), return an expression instead.
