Regex "The Basics" First 5 objectives Something strange I noticed Don't know if its intentional or not??
Here's the challenge: http://teamtreehouse.com/library/regular-expressions-in-python/introduction-to-regular-expressions/the-basics
Challenge Task 1 of 5 Use open() to load the file "basics.txt" into the variable file_object.
I use this code:
file_object = open("basics.txt", encoding="utf-8") data = file_object.read() file_object.close()
The above code gets me past the first 3 challenges
Notice I'm not using this import statement:
..at the beginning of the code.
Then I get to:
Challenge Task 4 of 5
..where it explicitly tells me to do the import:
Import re. Create an re.match() for the word "Four" in the data variable. Assign this to a new variable named first.
So what happens if I add the fourth line of code without the import re.
file_object = open("basics.txt", encoding="utf-8") data = file_object.read() file_object.close() first = re.match('Four', data)
I know this fourth line is correct will pass,
if import re was included
However...(the plot thickens..)
The error I think I should get is: Bummer! Did you forget to use import re
Instead the error I get is:
Oops! It looks like Task 1 is no longer passing.
If I use these code lines (which included the import re line of code)
import re file_object = open("basics.txt", encoding="utf-8") data = file_object.read() file_object.close()
the first 3 challenges pass just fine (even though it never told me to use import re until the 4th of 5th challenge)
Hmmmm...is this the usual (expected) behavior? (just wondering...)
From what I've seen not to many people have posted forum posts using these search parameters: https://teamtreehouse.com/forum/syllabus:1132 https://teamtreehouse.com/forum/stage:4612
..so this small 'glitch' might not have been picked up by anyone else..

import re file_object = open("basics.txt", encoding="utf-8") data = file_object.read() file_object.close() first = re.match('Four', data) libery = re.search ('Liberty', data)
I don't think you can take the treehouse as the replicating correctly python/php etc.. However did you click on the view button (forgot whats it called editor/view output or something, Just to the right of check work).. that should give you more correct and thorough errors.
I sometimes have a connection problem with treehouse when i am on stages 3 or 4. so what I do is i copy the entire code and refresh & paste.. and just press check work until I get to the stage where i left off and treehouse DOESNT moan why there is extra code.. I think their criteria is that it does what they require you at that stage AND there is no compiler error.. for example if you included import somethingTHatdoesntExist... it would give you an error..

file_object = open("basics.txt", encoding="utf-8") data = file_object.read()
Bummer! Did you close the file? whats going on?

this one works for me
file_object = open("basics.txt")

Why would a currently unneeded import cause the challenge to fail? It's just unnecessary code, it's not a bug. You wouldn't expect the challenge to fail because you wrote a completely unnecessary and unreferenced function, would you?
And, shez azr there's not really any "replicating" going on. We take your code and run it through Python to make sure it actually does what it's supposed to do.

Let me know what errors you find vague and I'll try to improve them.
fair enough.. If that is the case then your vague errors at the top led me to think so but then I also mentioned you get correct errors if you click on preview button..
