应该是少写了外层的中括号group = array([1.0,1.1],[1.0,1.0],[0,0],[0,0.1])改成下面的样子就ok吧，我是这样解决的。group = array([[1.0,1.1],[1.0,1.0],[0,0],[0,0.1]])

描述 Keyword-Only Arguments表示给函数传参的时候必须指定参数名,也就是关键字。 示例 一般函数的定义与传参方式: defmain(arg1, arg2):print(arg1, arg2) main(1,2) main(arg1=1, arg2=2) 定义: main函数定义两个参数arg1和arg2。 传参: 直接传参或指定参数名(关键字)传参都可以。 带强制关键字参...
在Python中,关键字参数(Keyword Arguments)是一种传递参数给函数的方法,它允许你通过参数名而不是位置来指定参数值。这使得函数调用更加清晰易读,并且可以避免由于参数顺序错误导致的问题。 如何使用关键字参数 在函数定义时: 在定义函数时,你可以为每个参数提供一个默认值。这样,在调用函数时如果没有提供该参数,则会...
运行时,报TypeError: write() takes no keyword arguments 我以为是write()函数不能接受两个参数,所以改成 f = open("a.txt","w") for items in txt: print(items) f.write(items+"\n") 运行时,报'gbk' codec can't encode character '\U0001f602' in position 17: illegal multibyte sequence错误...
{}.get(1,default=None)这个会报错: TypeError: get() takes no keyword arguments 因为这是底层API...
也即这里的age必须使用关键字参数的形式进行传值。 另外keyword-only arguments 还需要注意与列表参数进行区分,列表参数的 "*" 号是紧跟参数的,而非独占一个位置,且列表参数可以传零至多个值: def dog(name, host, *age): print(name, host, age) ...

Keyword arguments come up quite a bit in Python’s built-in functions as well as in the standard library and third party libraries. Requiring your arguments be named You can create a function that accepts any number of positional arguments as well as some keyword-only arguments by using the*...
This uses the*and**syntax to get all the arguments and keyword arguments and then usessuperto call the super-classes__init__with those arguments. The alternative (more work) is: def__init__(self, image, x, y):super().__init__(image=image, x=x, y=y)"""A test!"""print("Test...
