Using a variable in the later part of the program (python)












1















I'm trying to connect two separate codes into one program. I need to put one string from first to second part.



First:



import boto3

if __name__ == "__main__":

bucket='BUCKET-NAME'
collectionId='COLLECTION-ID'
fileName='input.jpg'
threshold = 70
maxFaces=1

client=boto3.client('rekognition')


response=client.search_faces_by_image(CollectionId=collectionId,
Image={'S3Object':{'Bucket':bucket,'Name':fileName}},
FaceMatchThreshold=threshold,
MaxFaces=maxFaces)


faceMatches=response['FaceMatches']
for match in faceMatches:
print (match['Face']['FaceId'])


Second:



import boto3
from boto3.dynamodb.conditions import Key, Attr

dynamodb = boto3.resource('dynamodb')

table = dynamodb.Table('faces')

response = table.scan(
FilterExpression=Attr('faceid').eq('FaceId')
)
items = response['Items']
print(items)


I need to put ID shown by print (match['Face']['FaceId']) from first code to FaceId in second code.



I tried to define a variable and put a value into it and then get it later but I could not do it correctly

  • Maybe, write the variable to a text file, and read it from the other code? P.S I have no idea how code on AWS is executed. If they are executed in parallel, then my next best guess would be to create an async call from the first script to the other.

  • Are these two separate programs, or simply separate sections of the same file? What is triggering each code block? I ask because the calling method could be used to pass information between the blocks.

  • If they are both in the same file, how does the second code block get called? You should either pass information between functions, or use a global variable to store something you need to access from multiple portions of code.

Typically, you're write your first block of code as a library/module with a function that does some unit of work and returns the result. Then the second block of code would import the first and call the function.



# lib.py
def SomeFunction(inputs):
output = doSomething(inputs)
return output

# main.py
import lib
data = ...
result = lib.SomeFunction(data)
moreWork(result)


If you want two separate programs that run independently and share data, you want Inter-process communication. You can get processes to share information with each other via: a file/fifo in the filesystem; a network socket; shared memory; and STDIO (and probably more). However, IPC is definitely more work than synchronous library calls.
