JSON: Access Array Values

See more JSON Examples

Demonstrates how to access values in a JSON array. Chilkat2-Python

import sys
import chilkat2

success = False

json = chilkat2.JsonObject()

jsonStr = "{ \"id\": 1, \"name\": \"A green door\", \"tags\": [\"home\", 22, \"green\"], \"price\": 125 }"

success = json.Load(jsonStr)
if (success != True):
    print(json.LastErrorText)
    sys.exit()

# Get the "tags" array, which contains "home", 22, "green"
# tagsArray is a CkJsonArray
tagsArray = json.ArrayOf("tags")
if (json.LastMethodSuccess == False):
    print("tags member not found.")
    sys.exit()

# Get the value at each array index. 
# Output will be:
# [0] = home
# [0] as integer = 0
# [1] = 22
# [1] as integer = 22
# [2] = green
# [2] as integer = 0

arraySize = tagsArray.Size

for i in range(0,arraySize):

    sValue = tagsArray.StringAt(i)

    print("[" + str(i) + "] = " + sValue)

    iValue = tagsArray.IntAt(i)
    print("[" + str(i) + "] as integer = " + str(iValue))

# Note: The StringAt method returns the value as a string regardless of the type.

# The IntAt method returns the value as an integer.  If the value does not convert to 
# an integer, then 0 is returned
