为什么浮点型 object 不能在这里调用？

Question

I'm trying to make a Taylor series in Python and I don't know how to remove this error:

x=Symbol("x")

def f(x):
    return ((math.e)**x)*sin(x)

y=f(x)

print(y.diff(x))

def Taylor(f,x,m,a):
    y=f(x)
    y2=f
    yargliige=0
    viga = 10**(-m)
    n=0
    while True:
        if n>10:
           return yargliige,n
        else:
           yargliige+=(y(x)*(x-a)**n)/(factorial(n))
           y=y.diff(x)
           if abs(yargliige(x)-f(x))<viga:
              return yargliige,n
        n+=1

print(Taylor(f,-0.3,3,-1))

Error message I get:

Traceback (most recent call last):
  File "C:\Users\arman\Desktop\Numbrilised meetodid\praktikum10.py", line 31, in <module>
    print(Taylor(f,-0.3,3,-1))
  File "C:\Users\arman\Desktop\Numbrilised meetodid\praktikum10.py", line 25, in Taylor
    yargliige+=(y(x)*(x-a)**n)/(factorial(n))
TypeError: 'Float' object is not callable

It seems that the original function doesn't accept float, which seems ridiculous.

Answer 1

You've already called y = f(x) which stores the returned float from the function f . You can not do y() as y is not callable. Change y = f(x) to y = f and it should solve your use case.

Answer 2

I see that you are trying to call yargliige as a function yargliige(x) which is not applicable since it's a variable not function.
