iterating over multiple dictionaries inside a list

Question

Here is my list with multiple dictionaries inside:

tags: [{
        'key': 'Environment',
        'value': 'Production'
    }, {
        'key': 'Environment',
        'value': 'Acceptance'
    }, {
        'key': 'Environment',
        'value': 'Test'
    }, {
        'key': 'Environment',
        'value': 'Development'
    }, {
        'key': 'Environment',
        'value': 'Sandbox'
    }]

Here the key value is always 'Environment' for all dictionaries. I need to check if the key is Environment, check if values are Production,Test,Development and Sandbox. If yes, print something.

How can achieve this ?

Please show what you've tried so far. It's customary on SO, as someone with a couple of hundred reps should know. — ShlomiF, Nov 28 '18 at 10:39

You could use all:

tags = [{
        'key': 'Environment',
        'value': 'Production'
    }, {
        'key': 'Environment',
        'value': 'Acceptance'
    }, {
        'key': 'Environment',
        'value': 'Test'
    }, {
        'key': 'Environment',
        'value': 'Development'
    }, {
        'key': 'Environment',
        'value': 'Sandbox'
    }]

result = all(tag['value'] in ('Sandbox', 'Test', 'Development', 'Production') for tag in tags if tag['key'] == 'Environment')
print(result)

Output

False

Note that the output is False because it contains the value 'Acceptance'.

this worked. thanks @Daniel Mesejo – Ebin Davis Nov 28 '18 at 19:02 — Ebin Davis, Nov 28 '18 at 19:02
