Hi there!

Let me start by saying this-- I have no experience with regular expressions. Simply put, I want a function that turns an array [eg: func(array)] into... an array, but add ONE space on both values. Meaning:

array = ['red','blue'] #returns ['red','blue']
array = func(array) # returns [' red ',' blue ']

Is it possible to do this? If so, how would I? If you could show me an example, and explain how you did it, that would be great! Thanks!

You don't need regex for this:

>>> array = ['red','blue']
>>> array1 = [' %s ' % item for item in array]
>>> array1
[' red ', ' blue ']

When you want to transform the elements of a list one by one, use the map function like this

def unstrip(theStr):
  return " %s " % theStr

theArray = ["red", "blue"]
# prints [" red ", " blue "]
print map(unstrip, theArray)

The list comprehension is posible too :)

I don't want to change the variable, per se, I just want to be able to check it as if the variable WAS like that through an if statement... does that make sense? I don't want to change the variable, I just want the value in my if statement to have the spaces.

It would be easier if we could see the if statement you need. Is it something like this ?

if map(unstrip, theArray) == [" red ", " blue "]:

def func(array)
arr = ['valueA','valueB']
if ' valueA ' in func(arr):

does this make sense?

It makes sense, but you should perhaps transform the value instead of the whole array, like this

if otherfunc(valueA) in arr:

for example here

arr = ["valueA", "valueB"]
if " valueA ".strip() in arr:

Thanks for your quick response-- unfortunately, in my case, that will not work, as I need the array's VALUES to have the whitespace... it's hard to explain, but that's what I need. :P Thanks!

Hmm... it's not letting me edit my post-- I got this working, though. Thanks, guys!
