duplicates

问题 I have a list of dictionaries in Python 3.5.2 that I am attempting to "deduplicate". All of the dictionaries are unique, but there is a specific key I would like to deduplicate on, keeping the dictionary with the most non-null values. For example, I have the following list of dictionaries: d1 = {"id":"a", "foo":"bar", "baz":"bat"} d2 = {"id":"b", "foo":"bar", "baz":None} d3 = {"id":"a", "foo":"bar", "baz":None} d4 = {"id":"b", "foo":"bar", "baz":"bat"} l = [d1, d2, d3, d4] I would like to

问题 I've some duplicated elements in my datastore (not the whole row, but most of the fields on it) in App Engine. What's the best way to find them? I've both integer and string fields that are duplicated (in case comparing one is faster than the other). Thanks! 回答1: An stupid but quick approach would be to take the fields you care about, concatenate them as a long string and store them as the key of an DB_Unique entity that references the original entity. Each time you do DB_Unique.get_or_insert

问题 I have a .txt document which consists of one word followed up with a date in one line, and so on in each line. How can Notepad++ recognize same words in different lines and delete duplicate lines? 回答1: Assuming the dates can be different for the same occurrence of the same word and you want to keep the one that appears first in the file then this should work (make sure your file end with a new line for this): Go to the "Replace" dialog (you can do Ctrl + F and go to replace tab). In the

问题 I`m using a script to remove duplicates on mongo, it worked in a collection with 10 items that I used as a test but when I used for the real collection with 6 million documents, I get an error. This is the script which I ran in Robomongo (now known as Robo 3T): var bulk = db.getCollection('RAW_COLLECTION').initializeOrderedBulkOp(); var count = 0; db.getCollection('RAW_COLLECTION').aggregate([ // Group on unique value storing _id values to array and count { "$group": { "_id": { RegisterNumber

问题 I have 2 different versions of the same project on my machine. One from the code trunk, and the other from a code branch. These projects use a .pfx key to enable strong naming. When I first tried to compile the trunk version of the project I get the following error: Cannot import the following key file: sgKey.pfx. The key file may be password protected. To correct this, try to import the certificate again or manually install the certificate to the Strong Name CSP with the following key
