python之把字符串形式的函数编译执行

Posted 2021-02-08 飞鸟_山东

实现效果：执行字符串形式的函数

代码如下

 1 # name = ‘aaa‘
 2 # data = [18,32,33]
 3 # def hellocute():
 4 #     return  "name %s ,age %d" %(name,data[0])
 5 # a = hellocute()
 6 # print(a)
 7 namespace = {‘name‘:‘aaa‘,‘data‘:[18,32,33]}
 8 code = """def hellocute():return  "name %s ,age %d" %(name,data[0])"""
 9 fun = compile(code,‘<string>‘,‘exec‘)
10 exec(fun,namespace)
11 print(namespace)
12 ret = namespace[‘hellocute‘]()
13 print(ret)
