在python函数中，如何传递要筛选的可选参数
如何将可选参数传递给用户定义函数，而当调用该参数时，它会过滤原始数据，而当忽略该参数时，则不会过滤原始数据在python函数中，如何传递要筛选的可选参数,python,Python,如何将可选参数传递给用户定义函数，而当调用该参数时，它会过滤原始数据，而当忽略该参数时，则不会过滤原始数据 import spacy from collections import Counter nlp = spacy.load('en') txt=“””Though the disease was eradicated decades ago, national security experts fear that stocks of the virus in labs could be r

pos如果它是真实的，则基本上只按
posdef common_pos(doc, n, pos='VERB'):
将接受您给予它的任何内容，但如果您不接受，它将成为
“动词”def common_pos(doc, n, pos='VERB'):
我会接受你给它的任何东西，但如果你不接受，它就会变成动词。顺便说一句，你需要去掉那些“智能引号”，“代码”，“代码”和“代码”，它们在Python中是无效的。不要使用类似于Word的程序来编辑程序文本，请使用适当的程序员编辑器或IDE。顺便说一句，您需要从您的脚本中删除那些“智能引号”、
