How to print all multi-column variable text in reading order

Hi
I've been trying to extract only the text in reading order for multi-column cases with the code below.
His problem is that the number of columns is manual.
I've been trying to deploy the response-parser in this code but I couldn't, could you give an example of how to do it?
What I've achieved so far with amazon-textracr-response-parser keeps mixing up the reading order.

```
# Document
s3BucketName = "your-bucket-name"
documentName = "your-image.png"

# Call Amazon Textract
response = textract.detect_document_text(
Document={
'S3Object': {
'Bucket': s3BucketName,
'Name': documentName
}
})

print(response)

# Detect columns and print lines
columns = []
lines = []
for item in response["Blocks"]:
if item["BlockType"] == "LINE":
column_found=False
for index, column in enumerate(columns):
bbox_left = item["Geometry"]["BoundingBox"]["Left"]
bbox_right = item["Geometry"]["BoundingBox"]["Left"] + item["Geometry"]["BoundingBox"]["Width"]
# Divide by the number of existing columns
# manual input that I need to resolve to sort either with 1, 2, 3, 4 or 5 columns
bbox_centre = item["Geometry"]["BoundingBox"]["Left"] + item["Geometry"]["BoundingBox"]["Width"]/2
column_centre = column['left'] + column['right']/2

if (bbox_centre > column['left'] and bbox_centre < column['right']) or (column_centre > bbox_left and column_centre < bbox_right):
#Bbox appears inside the column
lines.append([index, item["Text"]])
column_found=True
break
if not column_found:
columns.append({'left':item["Geometry"]["BoundingBox"]["Left"], 'right':item["Geometry"]["BoundingBox"]["Left"] + item["Geometry"]["BoundingBox"]["Width"]})
lines.append([len(columns)-1, item["Text"]])

lines.sort(key=lambda x: x[0])
for line in lines:
print (line[1])
```
