Python SyntaxError: non-keyword after keyword arg is an error which occurs when you put non-keyword arguments and keyword arguments in the wrong order.
In the blog post I attempt to explain why this error takes place and how you can solve it, I will also add other solutions that could solve the error if possible.
Exploring Python SyntaxError: non-keyword after keyword arg
This is an error which occurs when you put non-keyword arguments and keyword arguments in the wrong order.
The error can occur because of simple lines of code just like the examples bellow.
#
inputFile = open((a), encoding = "ASCII", "n=True")
#
#
inputFile = open((a), encoding = "utf8", "r")
#
#
inputFile = open((a), name = "Yara", "present=True")
#
Do not mix between errors. Make sure the error message looks like the error message bellow after double checking.

In the section bellow we will explain the root of the error more and propose a possible fixe.
Solution : flip the position of the non-keyword args and the keyword args
Unlike other errors in python, this error is very clear, the error says non-keyword arg after keyword arg.
This means you have the arguments flipped, since in python non-keyword args should be positioned before normal keyword args.
This is how non-keyword args look like in python.
#
date="02/09/2000", rank="1323", gender="male", age="30"
#
Normal keyword args or fixed parameters look like this
#
present=False, active=True, open=True
#
So if you do something like this
#
inputFile = open((a), encoding = "utf8", "r")
#
or this
#
inputFile = open((a), encoding = "ASCII", "n=True")
#
or this
#
inputFile = open((a), name = "Yara", "present=True")
#
You are making a big mistake. The solution is to flip the arguments and use this.
#
inputFile = open((x), "r", encoding = "utf8")
#
or this, for the second example
#
inputFile = open((x), "n=True", encoding = "ASCII")
#
#
inputFile = open((a), "present=True", name = "Yara")
#
