Collections are groups of items. Python supports several types of collections. Three of the most common are dictionaries, lists and arrays.
Lists are a collection of items. Lists can be expanded or contracted as needed, and can contain any data type. Lists are most commonly used to store a single column collection of information, however it is possible to nest lists
Arrays are similar to lists, however are designed to store a uniform basic data type, such as integers or floating point numbers.
Dictionaries are key/value pairs of a collection of items. Unlike a list where items can only be accessed by their index or value, dictionaries use keys to identify each item.

# Challenge #1 # Create an Azure Custom Vision Service # Analyze an image and return the JSON describing the image. # call_api.py is a completed solution, but it will not run unless # you do the following: # Create a Custom Vision Service in Azure # Update the Key # Update the address of your service # Update the image file and location # Bonus Challenge # Your skills are growing, it's time to start trying to figure things out on your own # based on documentation. You have already called one function of the Computer Vision Service # Now try calling another # Instead of calling the analyze method of the service, try calling the OCR method # Here is some helpful documentation # https://docs.microsoft.com/azure/cognitive-services/Computer-vision/concept-recognizing-text#ocr-optical-character-recognition-api # https://westus.dev.cognitive.microsoft.com/docs/services/5adf991815e1060e6355ad44/operations/56f91f2e778daf14a499e1fc # Use the documentation to figure out # The correct function name for the address # The parameters you need to pass the function # The HTTP Headers required # Pass in an image containing text # The JSON returned will contain the string of text in the image # Good luck!
