如何将运算符传递给 python 函数? [英] How to pass an operator to a python function?

问题描述

我想将数学运算符以及要比较的数值传递给函数.这是我损坏的代码:

I'd like to pass a math operator, along with the numeric values to compare, to a function. Here is my broken code:

def get_truth(inp,relate,cut):    
    if inp print(relate) cut:
        return True
    else:
        return False

并调用它

get_truth(1.0,'>',0.0)

应该返回 True.

推荐答案

看看 运营商模块:

import operator
get_truth(1.0, operator.gt, 0.0)

...

def get_truth(inp, relate, cut):    
    return relate(inp, cut)
    # you don't actually need an if statement here
