如何调用组合或同时调用这两个函数？

# 示例函数1
def func1(input):
    # 函数逻辑
    output = input + 1
    return output

# 示例函数2
def func2(input):
    # 函数逻辑
    output = input * 2
    return output

# 串行调用
result1 = func1(10)
result2 = func2(result1)

# 并行调用（多线程）
import threading

def parallel_call():
    result1 = func1(10)
    result2 = func2(10)
    # 处理结果

thread1 = threading.Thread(target=parallel_call)
thread1.start()

# 函数组合
def compose(f, g):
    def composed_function(x):
        return f(g(x))
    return composed_function

composed_func = compose(func2, func1)
result3 = composed_func(10)
