也就是说exec可以执行复杂的python代码,而不像eval函数那样只能计算一个表达式的值。 exec(source, globals=None, locals=None, /) source:必选参数,表示需要被指定的python代码。它必须是字符串或code对象。如果source是一个字符串,该字符串会先被解析为一组python语句,然后执行。如果source是一个code对象,那么它...
Python 提供了很多内置的工具函数(Built-in Functions),在最新的 Python 3 官方文档中,它列出了 69 个。 大部分函数是我们经常使用的,例如 print()、open() 与 dir(),而有一些函数虽然不常用,但它们在某些场景下,却能发挥出不一般的作用。内置函数们能够被“提拔”出来,这就意味着它们皆有独到之处,有用武...

Allows the distributed execution of an arbitrary R function in parallel, across nodes (computers) or cores of a “compute context”, such as a cluster. For example, you could use the function to execute multiple instances of a model concurrently. When us
