Challenge: Scientific Computing with Python Projects - Arithmetic Formatter
Link to the challenge:
hi there, welcome to the forum. What question did you want to ask?
i am having a challenge of getting the test incorrect operator from the unicast pytest, what should i do?
I am sorry, I didn’t understand. Can you rephrase or show me a screenshot of the error you are having?
Please post the url of the replit you are using for this.
The problem is the following logic:
if re.search("[/] [*]", problem):
return ("Error: Operators must be '+' or '-'.")
First, you have a typo in the return statement.
Second, "[/] [*]" is not doing what you think it is doing. You need to make a slight modification to your regular expression. The above expression searches for the case where / is immediately followed by a space character and then immediately followed by *
Something else to consider even though the existing tests to not test for it, would your function return the correct value for the following cases?
arithmetic_arranger(["32 ++ 698", "3801 - 2", "45 + 43", "123 + 49"])
or
arithmetic_arranger(["32 = 698", "3801 - 2", "45 + 43", "123 + 49"])
