Python - 将一个函数传递给另一个函数 [英] Python - Passing a function into another function

问题描述

我正在使用 python 解决一个谜题，根据我正在解决的谜题，我将不得不使用一组特殊的规则.如何将一个函数传递给 Python 中的另一个函数?

I am solving a puzzle using python and depending on which puzzle I am solving I will have to use a special set of rules. How can I pass a function into another function in Python?

示例

def Game(listA, listB, rules):
   if rules == True:
      do...
   else:
      do...

def Rule1(v):
  if "variable_name1" in v:
      return False
  elif "variable_name2" in v:
      return False
  else:
      return True

def Rule2(v):
  if "variable_name3" and "variable_name4" in v:
      return False
  elif "variable_name4" and variable_name1 in v:
      return False
  else:
      return True

这只是一个伪代码，因此不是特定的，但我得到了要编译的代码，但我需要知道如何调用函数 Game 以及它是否正确定义，因为规则将切换为Rule1(v) 或 Rule2(v).

This is just a pseudo code and therefore not specific but I get the code to compile but I need to know how to call the function Game and whether it's correctly defined since rules will be switched for either Rule1(v) or Rule2(v).

推荐答案

就像传入任何其他参数一样:

Just pass it in like any other parameter:

def a(x):
    return "a(%s)" % (x,)

def b(f,x):
    return f(x)

print b(a,10)
