Python函数如何先return一个信息，再继续执行后续代码

Python语言，函数A调用函数B，B先return一个信息给A，接着调用函数C，请问如何实现

def C():
    print("C")
    
def myfunc():
    yield 123
    C()
    yield 456

def A():
    gen = myfunc()
    print(gen.__next__())
    print("然后继续执行")
    gen.__next__()
    
A()

def functionA():
    # 调用函数B并接收返回的信息
    info = functionB()
    
    # 在这里可以使用返回的信息进行处理
    print("Received info from functionB:", info)
    
    # 继续执行后续代码
    functionC()

def functionB():
    # 返回一个信息给调用它的函数
    return "Hello from functionB!"

def functionC():
    print("This is functionC.")

# 调用函数A
functionA()

输出

Received info from functionB: Hello from functionB!
This is functionC.

  在函数B中，可以通过input()函数让用户输入信息，并保存在一个变量中。然后再返回这个变量给函数A。具体实现可以参考如下代码：

  def functionB():
      user_input = input("Please enter information:")
      return user_input
  
  def functionA():
      result_from_B = functionB()
      #continue to execute the code in functionA
      return result_from_B
