python - 从列表项调用函数

Question

我想根据调用的键调用字典中命名的函数。

示例:

start_options = {'left': 'octopus', 'right': 'lion', 'small': 'pit', 'small door': 'pit'}

choice = raw_input("What do you want to do? ").lower()
        if choice in dictionary:
            print "found: " + choice, start_options[choice]
            print "You chose " + choice
            #code here will call function

def octopus():
    #do something

Answer 1

如果您事先定义了函数，则可以直接在字典中引用它们，而不是字符串表示形式:

def yada():
    print("Yada!")

def blah():
    print("Blah!")

start_options = {'test1': yada, 'test2': blah}
start_options['test1']()

运行此代码会产生:

Yada!
