Loop through array of json objects

Question

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. — RoadRunner, Nov 12 '18 at 05:18
What you have there is not a JSON array. It is a Python structure of a list of dictionaries. — Klaus D., Nov 12 '18 at 05:23

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'])

The syntax is right just add a colon after the for statement

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