Python: SyntaxError: non-keyword after keyword arg
提问by
When I run the following code
当我运行以下代码时
def regEx1():
os.chdir("C:/Users/Luke/Desktop/myFiles")
files = os.listdir(".")
os.mkdir("C:/Users/Luke/Desktop/FilesWithRegEx")
regex_txt = input("Please enter the website your are looking for:")
for x in (files):
inputFile = open((x), encoding = "utf8", "r")
content = inputFile.read()
inputFile.close()
regex = re.compile(regex_txt, re.IGNORECASE)
if re.search(regex, content)is not None:
shutil.copy(x, "C:/Users/Luke/Desktop/FilesWithRegEx")
I get the following error message which points to the first line after the for loop.
我收到以下错误消息，它指向 for 循环后的第一行。

It's just what it says:
这就是它所说的：
inputFile = open((x), encoding = "utf8", "r")
You have specified encodingas a keyword argument, but "r"as a positional argument. You can't have positional arguments after keyword arguments. Perhaps you wanted to do:
您已指定encoding为关键字参数，但指定为"r"位置参数。关键字参数后不能有位置参数。也许你想做：
inputFile = open((x), "r", encoding = "utf8")
