json file
JSON (JavaScript Object Notation) is a lightweight data exchange format. Can be used as a text file. Here are two ways to read json files, for comparison. The main two methods of reading json files lead to slightly different subsequent codes.
Predict1_-mixer.json:
{
"projection": {
"crs": "EPSG:4326",
"affine": {
"doubleMatrix": [8.983152841195215E-4, 0.0, 13.599595086285436, 0.0, -8.983152841195215E-4, 45.40175277468474]
}
},
"patchDimensions": [256, 256],
"patchesPerRow": 5,
"totalPatches": 10
}
{
'projection': {
'crs': 'EPSG:4326', 'affine': {
'doubleMatrix': [0.0008983152841195215, 0.0, 13.599595086285436, 0.0, -0.0008983152841195215, 45.40175277468474]}}, 'patchDimensions': [256, 256], 'patchesPerRow': 5, 'totalPatches': 10}
!cat
import json
jsonFile='Predict1_-mixer.json'
jsonText = !cat {
jsonFile}
mixer = json.loads(jsonText.nlstr)
patches = mixer['totalPatches']
patchesPerRow = mixer['patchesPerRow']
The jsonText of this method needs further processing:
['{',
' "projection": {',
' "crs": "EPSG:4326",',
' "affine": {',
' "doubleMatrix": [8.983152841195215E-4, 0.0, 13.599595086285436, 0.0, -8.983152841195215E-4, 45.40175277468474]',
' }',
' },',
' "patchDimensions": [256, 256],',
' "patchesPerRow": 5,',
' "totalPatches": 10',
'}']
The mixer output is as follows:
{
'patchDimensions': [256, 256],
'patchesPerRow': 5,
'projection': {
'affine': {
'doubleMatrix': [0.0008983152841195215,
0.0,
13.599595086285436,
0.0,
-0.0008983152841195215,
45.40175277468474]},
'crs': 'EPSG:4326'},
'totalPatches': 10}
open()
import json
jsonFile='Predict1_-mixer.json'
with open(jsonFile, 'r') as myfile:
jsonText=myfile.read()
mixer = json.loads(jsonText)
patches = mixer['totalPatches']
patchesPerRow = mixer['patchesPerRow']
The method jsonFile does not require further processing , and can be directly loads():
{
"projection": {
"crs": "EPSG:4326",
"affine": {
"doubleMatrix": [8.983152841195215E-4, 0.0, 13.599595086285436, 0.0, -8.983152841195215E-4, 45.40175277468474]
}
},
"patchDimensions": [256, 256],
"patchesPerRow": 5,
"totalPatches": 10
}
The mixer output is consistent:
{
'patchDimensions': [256, 256],
'patchesPerRow': 5,
'projection': {
'affine': {
'doubleMatrix': [0.0008983152841195215,
0.0,
13.599595086285436,
0.0,
-0.0008983152841195215,
45.40175277468474]},
'crs': 'EPSG:4326'},
'totalPatches': 10}
