Loop through array of json objects










0














What is the correct way to loop through the following json object?



test = [
'start': 'ieo5',
'end': 'tiu9',
'chain': 10489
,
'start': 'qvc5',
'end': 'tiu9',
'chain': 45214
,
'start': 'ieo5',
'end': 'tiu9',
'chain': 69296
]


I essentially want to loop through and print out whatever the value of start is.



I've tried a bunch of options like the ones listed here but can't seem to get it to work.



This doesn't work:



for x in test
print x['start']

    Use print(x['start']) instead. Python 3 needs parentheses in print calls.

    Also, : at the end of for line.

    What you have there is not a JSON array. It is a Python structure of a list of dictionaries.

Your code logic works fine, just few things making it not work:



  • Since the tag is python-3.x, print needs to be called.


  • Need colon after for line.


So the code would look like:



for x in test:
print(x['start'])
