If you don't have an Azure subscription, create a free account before you begin. This quickstart uses a local file. To use a receipt image accessed by URL instead, see the reference documentation. Go to the Azure portal and create a new Form Recognizer resource. In the Create pane, provide the following information:. Normally when you create a Cognitive Service resource in the Azure portal, you have the option to create a multi-service subscription key used across multiple cognitive services or a single-service subscription key used only with a specific cognitive service.

However currently Form Recognizer is not included in the multi-service subscription. When your Form Recognizer resource finishes deploying, find and select it from the All resources list in the portal. Your key and endpoint will be located on the resource's key and endpoint page, under resource management. Save both of these to a temporary location before going forward. Before you run the script, make these changes:. The Analzye Receipt 2. You'll receive a Success response that includes an Operation-Location header, which the script will print to the console.

This header contains an operation ID that you can use to query the status of the asynchronous operation and get the results. Add the following code to the bottom of your Python script.

This script calls the API at regular intervals until the results are available. We recommend an interval of one second or more. The script will print responses to the console until the Analyze Receipt operation completes. Then, it will print the extracted text data in JSON format.

See the following receipt image and its corresponding JSON output. The output has been shortened for readability. The "readResults" node contains all of the recognized text. Text is organized by page, then by line, then by individual words. The "documentResults" node contains the receipt-specific values that the model discovered.

What is the issue with the code you are supposed to use?

The -1 breaks it so it won't continue. The issue is that I need to make a list and add dollar signs. This means price is no longer a list when they've finished execution. Active Oldest Votes.

Code Review Stack Exchange is a question and answer site for peer programmer code reviews. It only takes a minute to sign up. I've been working on a parser for shop receipts which extracts data about the payment. Here is the text that I'm parsing:. Here is the code that parses this fragment from the receipt. Your code is a lot of repetition of exactly the same pattern, with only the string changing. This has the advantage that if you ever have receipts in another language than Dutch but with the same structureyou only need to localize the values of this dictionary and not change your whole code.

Note that I used str. A different approach might be to use a multi-line RegEx to perform the search directly, but that will probably be more complicated. Due to the extra : in the lines, POI and Datum are parsed incorrectly. Instead of a giant if-elseif-if tree, I would as a function that parses a line, and returns the type of line with the value. Note that I split on ": ". The space makes the parsing of the date correct. The [] selects the last 2 items, making the POI parse correctly. In this simple case I would use the first parser method.

If the patterns get a little more complicated, You can change to the re. Here I would use a dictionary that links all keywords in your return dictionary to the keys in the parsed lines:. Since functions can be values in a dictionary, you can add functions to further process the values. For example convert thetotal to a tuple of value, currencytransform the date from a string to a datetime object,By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Code Review Stack Exchange is a question and answer site for peer programmer code reviews. It only takes a minute to sign up. My code takes input from the user and creates a receipt with the information the program receives from the user:. Are there any ways to improve the efficiency of the code and shorten it? Is there anything I should improve in my code?

You have way too many global variables and this is a problem because a global variable may, by definition, be modified from anywhere in your program.

This means that the reader of your program has to keep in mind all the values of all the variables at the same time. Now for a small script like this this is no big deal, but imagine having not 5 global variables but 50 of them.

Now you understand how hard it can become to follow un-organized code. I suggest that each function should take the variables that it operates on as arguments and, if it modifies them, then it should return the new values back.

For example the function that prints out the final recipe can easily be adjusted to take as arguments the three arrays. I see that you keep a variable that indicates how long the input list is; that is premature optimization because you may just recalculate the length just before looping. In fact in a user interface driven program you should not worry at all about performance because computers are very very fast nowadays. To be complete there is an even more efficient way of looping, that is using the zip built in but that is a more advanced topic.

I think the whole try except block should be extracted into its own function as getting an input that must be a number from the user is a pretty common task. Lastly, while 1 makes your intention slightly less clear than while True. In Python striving for English-like semantics whenever performance isn't critical is considered a common practice.

Before asking that ask if there is any need to improve the efficiency and shorten it. Readability nowadays adds much more value than performance tweaks.

Writing code that your peers don't understand is a much bigger problem than doing inefficient loops. Instead of maintaining multiple global arrays, they can be represented by a class and its members.

Otherwise Python's garbage collection would reuse the objects and we had no way to access the inputs as we had no way to access them. We have not individual names for each item, but one list to store them all. Oh ok, thank you mennow everything is clear. Facebook Like. Twitter Tweet. Be a part of the DaniWeb community.
