在python中计算一系列函数

Question

I want to get the result of a chain of computations from an initial value. I'm actually using the following code:

def function_composition(function_list, origin):
    destination = origin
    for func in function_list:
        destination = func(destination)
    return destination

With each function in function_list having a single argument.

I'd like to know if there is a similar function in python standard library or a better way (example: using lambdas) to do this.

destination = reduce((lambda x, y: y(x)), function_list, origin)
