Hope that helps , The re module will work for this, if you use a positive lookbehind:
your_text = "If I can ease one life the aching,"
re.sub("(?<=[ah]i).{3}", "***", your_text)
'If I can ease one life the achi***'

Is there a better way to perform URL pattern matching in C++ than iteration?


Tag : cpp , By : Govind Bhavan

With these it helps The way I see it, you could split the URL into its components (using one of the suggestions in here maybe), and then use a decision tree to find the correct pattern.
In this tree, every node would be a regular expression that matches a particular component of your URL, and the leaves would be the values you currently store in your map:
                                 session
                                    |   \
                                    |    1
                                    |
                              ([0-9a-fA-F-]+)
                              /     |     \
                             /      |      \
                           url     back    element
                            |       |       |     \
                            |       |       |      5
                            2       3       |
                                        ([0-9a-fA-F-]+)

RESTKit 2.0: Pattern string must not be empty in order to perform pattern matching


Tag : ios , By : Nathan Good

I hope this helps you . When you create responseDescriptor this is added to the RKObjectManager you use pathPattern:nil. This is not permitted. You must specify a path pattern as RestKit must lookup the appropriate response descriptor to apply to the received response.
Later, you again use pathPattern:nil, but this is directly with an RKObjectRequestOperation. In this case it is allowed (and thus works) because you have provided an explicit list and no lookup is required.

Perform pattern matching and guard at the same time

hope this fix your issue I want to perform pattern matching over a Maybe expression and apply a guard at once, something like: , This can be accomplished with a normal case block:
case myFunction 333 of
    Just val | val > 0               ->  "> 0 " ++ show val  
             | val == 0              -> "== 0 " ++ show val
             | val < -5 && val > -10 -> "< -5 and > -10 " ++ show val
    _ -> "otherwise"

How to perform pattern matching between two strings?


Tag : python , By : liquidx

seems to work fine How about the following approach. Split each into words, lowercase each word and store in a set. x must then be a subset of y. So for your example it will fail as 16 does not match 64:
x = "Apple iPhone 6(Silver, 16 GB)"
y = "Apple iPhone 6 64 GB GSM Mobile Phone (Silver)"

set_x = set([item.lower() for item in re.findall("([a-zA-Z0-9]+)", x)])
set_y = set([item.lower() for item in re.findall("([a-zA-Z0-9]+)", y)])

print set_x
print set_y

print set_x.issubset(set_y)
set(['apple', '16', 'gb', '6', 'silver', 'iphone'])
set(['apple', 'mobile', 'phone', '64', 'gb', '6', 'gsm', 'silver', 'iphone'])
False
set(['apple', '16', 'gb', '6', 'silver', 'iphone'])
set(['apple', '16', 'mobile', 'phone', 'gb', '6', 'gsm', 'silver', 'iphone'])
True
