title: How can I use values given by result.fit_report()?
body: <p>I've done the fit of a double Guassian function using the Lmfit library. </p>
  
  <pre><code>gmodel = Model(myDGauss)
  result = gmodel.fit(yGauss, x=xGauss, I1=2.47,I2=2.63,sigma1=1.07,sigma2=1.15)
  </code></pre>
  
  <p>I've printed the fit report using the method fit_report():</p>
  
  <pre><code>print(result.fit_report())
  </code></pre>
  
  <p>and I've got what shown below:</p>
  
  <pre><code>[[Fit Statistics]]
      # fitting method   = leastsq
      # function evals   = 76
      # data points      = 130
      # variables        = 4
      chi-square         = 0.00559033
      reduced chi-square = 4.4368e-05
      Akaike info crit   = -1299.05274
      Bayesian info crit = -1287.58260 [[Variables]]

      I1:      0.74813688 +/- 0.01143576 (1.53%) (init = 2.475306)
      I2:      0.23722309 +/- 0.01099214 (4.63%) (init = 2.638552)
      sigma1:  1.23574890 +/- 0.00724975 (0.59%) (init = 1.070258)
      sigma2:  0.57214098 +/- 0.01513481 (2.65%) (init = 1.157566)
  </code></pre>
  
  <p>What I'd like to do now is to save the values of the fit_report printed in some variables. For example, I'd like to put the value of <code>I1</code> printed (0.74813688) in the variable <code>valI1</code>, that is a variable inizialized to 0.</p>
  
  <p>Could anyone help me, please? Thanks</p>
