python - ValueError while using scipy.integrate to calculate value of a function -

-

I am trying to evaluate the function for different values ​​of a variable n I made a NP Linsep and function of the momentum Q : 

  def Q (z_i, z_min, f_gamma, mdm, sigma_v, n, with_ucmh) plug-in in: DQdz_z = lambda Z: Dikyudijh (F_ Gemma, MDM, Sigma_vi, Z, N, Sath_kyuemac) integrated = lambda z: ((1 / ((1 + z) * Ac_jh (Z))) * (Dikyudijh_jh ( Z)) * np. (z)) second_part = const.C * const .B * integrate.romberg (integrand, z_min, z_i) return second_part z_i = 2.0e6 z_min = 5.0e4 sigma_v = 3.0e-27 f_gamma = 1. MDM = 10. with_ucmh = true n = np.linspace (1., 1.3 100) mu = Q (z_i, z_min, f_gamma, mdm, sigma_v, n, with_ucmh)

I value error: an array element with a sequence Installing indicates me for the line where I use integrity. Use the method of gravity, but I do not understand how I get such error here.

I am not completely sure how to fix it.

I would like to create a fuel bar (empty with full tank). When the user touches the screen, the fuel once Dairejh these is my code: lifeBar = display.newImage ( "fuel_bar1.png") lifeBar.anchorX = 0 lifeboats. ======================== Lifetime Y = 37 screens Group: The Insert function (called Laifbar) However, I fuel Kansmoshn (equivalent to "pressed" variable to reduce the fuel tank "true") Have used. When pressed == is true, it means that the user is touching the screen: processed (fuel) processed () if life & gt; 0 and pressed == true remains = life - life 1 Life = life =. Wide-1 remains Value.text = string.format ("% d", life) End of this This function is active as the entrance event: runtime: addEventListener ( "Antrfrem" fuel Snsadna) it is very well, but my question is: pressed variable each time 5 seconds (once = = True) How is it possible to reduce the vitality width? I tried to add it to my touch even...
