错误:'str'对象没有属性'_meta'

我们试图解析字典,但它说它是一个字符串？是因为一个字典中有多个对象吗？

我在 bash_profile 文件中定义了一个函数。

pse(){
ps -ef|grep $1
}

现在我可以从命令行调用这个函数。喜欢

pse kafka

它工作正常，因为我可以看到正确的输出。但是当我尝试在脚本文件中调用 pse 函数时，它向我显示“命令未找到”错误。我错过了什么吗？我们是否不允许从 shell 脚本调用 bash_profile 中定义的函数？操作系统：MacOSX 优胜美地

我有这两个词:

a={"test1":90,  "test2":45,  "test3":67,  "test4":74}
b={"test1":32,  "test2":45,  "test3":82,  "test4":100}

如何提取相同键的最大值以获得新的dict,如下所示:

c={"test1":90,  "test2":45,  "test3":82,  "test4":100}
