Python - TypeError: float object is not callable error

Question

Have got the following code so far:

class beam(object):

    def __init__(self, E, I, L):
         self.E = E  
         self.I = I  
         self.L = L  
              


        

Answer 1

The only way that this could happen is if you pass a float to derivative() in place of a function:

>>> scipy.misc.derivative(1.0, 1.0)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib64/python2.7/site-packages/scipy/misc/common.py", line 195, in derivative
    val += weights[k]*func(x0+(k-ho)*dx,*args)
TypeError: 'float' object is not callable

Are you absolutely sure that your code is as posted? Most likely your code is actually calling self.getTotalDeflection and therefore passing its return value (a float) to derivative(), e.g. your code might be:

return scipy.misc.derivative(self.getTotalDeflection(x), x)

or similar, when it should really be as you have posted, i.e.

return scipy.misc.derivative(self.getTotalDeflection, x)
