I am trying to separate a section of a document into its different components which are separated by ampersands. This is what I have:
我试图将文档的一个部分分离到由&号分隔的不同组件中。这就是我所拥有的:
name,function,range,w,h,k,frac,constraint = str.split(str="&", num=8)
Error:
错误:
TypeError: split() takes no keyword arguments
Can someone explain the error to me and also provide an alternate method for me to make this work?
谁能给我解释一下这个错误，并为我提供另一种方法来实现这个功能吗?

The parameters of str.split are called sep and maxsplit:
string .split的参数分别为sep和maxsplit:
str.split(sep="&", maxsplit=8)
But you can only use the parameter names like this in Python 3.x. In Python 2.x, you need to do:
但是您只能在Python 3.x中使用这样的参数名。在Python中2。x，你需要做:
str.split("&", 8)
which in my opinion is the best for both versions since using the names is really just redundant. str.split is a very well known tool in Python, so I doubt any Python programmers will have trouble understanding what the arguments to the method mean.
在我看来，这对两个版本都是最好的，因为使用名字是多余的。split是Python中一个非常有名的工具，因此我怀疑任何Python程序员都不会理解方法的参数的含义。
Also, you should avoid making user-defined names the same as one of the built-in names. Doing this overshadows the built-in and makes it unusable in the current scope. So, I'd pick a different name for your string besides str.
此外，应该避免让用户定义的名称与内置名称中的一个名称相同。这样做会使内置程序蒙上阴影，使其在当前范围内无法使用。那么，除了str，我还要为你的字符串取一个不同的名字。

The error states that you can't provide named arguments to split. You have to call split with just the arguments - without the names of the arguments:
错误声明不能为split提供命名参数。你必须只使用参数调用split——不使用参数的名称:
name,function,range,w,h,k,frac,constraint = str.split("&", 8)

split doesnt get keyword arguments str or num. Do this instead:
split不会得到关键字参数str或num。
name,function,range,w,h,k,frac,constraint = str.split('&', 8)
