# scipy.spatial.distance.cityblock

scipy.spatial.distance.cityblock(u, v, w=None)

  Compute the City Block (Manhattan) distance.

  Computes the Manhattan distance between two 1-D arrays u and v, which is defined as

  \[\sum_i {\left| u_i - v_i \right|}.\]
  Parameters:
    u(N,) array_like

      Input array.

    v(N,) array_like

      Input array.

    w(N,) array_like, optional

      The weights for each value in u and v. Default is None, which gives each value a weight of 1.0

  Returns:
    cityblock double

      The City Block (Manhattan) distance between vectors u and v.

  Examples

      >>> from scipy.spatial import distance
      >>> distance.cityblock([1, 0, 0], [0, 1, 0])
      2
      >>> distance.cityblock([1, 0, 0], [0, 2, 0])
      3
      >>> distance.cityblock([1, 0, 0], [1, 1, 0])
