How do get Sympy (in python) to plug in a given value for a function?

So I am currently in Calculus 2 and we recently began talking about Taylor Series (yay....), becuase its a natoriously hard topic, my teacher recomended we write a programing code that is able to do Taylor Series in order to better understand the mechanics. So far this has really helped and I was able to get it to find the 4 deritives but I am not sure how to get it to plug in the correct C value into the function and the 4 deritives. Can someone show me what do do next? Thanks:

import sympy as sy
sy.init_printing()

H=0

#Variables
while H!=100:
    
    x=sy.symbols("x")
    f=(input('Please enter function, x '))
    c=int(input('Enter the center of the equasion, c '))

    #Derivatives
    dx=sy.Derivative(f)
    dx=dx.doit()
    Dx=sy.Derivative(dx)
    Dx=Dx.doit()
    DX=sy.Derivative(Dx)
    DX=DX.doit()
    D_X=sy.Derivative(DX)
    D_X=D_X.doit()
    H=H+1
    print('The First Deritive, is:')
    print(dx)
    print('The Second Deritive, is:')
    print(Dx)
    print('The Third Deritive, is:')
    print(DX)
    print('The Fourth Deritive, is:')
    print(D_X)

Allow me to point out that d1x, d2x, d3x and d4x would be much better names than dx, Dx, DX, and D_X.

    print('The First derivative, is:')
    print(dx)
    print(f'The value of the first derivative at {c} is:')
    print(dx.subs(x,c))
    print('The Second derivative, is:')
    print(Dx)
    print(f'The value of the second derivative at {c} is:')
    print(Dx.subs(x,c))
    print('The Third derivative, is:')
    print(DX)
    print(f'The value of the third derivative at {c} is:')
    print(DX.subs(x,c))
    print('The Fourth derivative is:')
    print(D_X)
    print(f'The value of the fourth derivative at {c} is:')
    print(D_X.subs(x,c))
