我如何将这个公式合并到我的 python 程序中？

Question

I am new to Python and trying to figure a way to input numbers to a mathematical formula.

Mathematical formula as shown:

I have developed based on the above formula, but not fully sure why it cant work.

def cumulative_function():
    alpha = 0.05
    fx_value = 5
    variable_a = -100
    k = 2
    cdf_formula = alpha * (fx_value * (a) + fx_value * (k - 2 * (alpha) + fx * (k - alpha) + fx_value * (value_x)))
    return cdf_formula

cdf = cumulative_function()
print (f"value is: {cdf}")

*EDIT: How do I insert the infinity ('...') in the formula to my program? Would appreciate anyone who can help me out:)

Answer 1

fx(a) is not fx *(a) but actually a function to which you are passing a value 'a'

• for example let fx()=x*2+x
• then fx(a) will be a*2+a
• fx(5) will be 5*2+5=10+15
