How to access a dictionary value inside a list?

I would like to access the value of the following :

a = [{'translation_text': 'I love cake.'}]

Desired output:

"I love cake."

I tried the following:

a['translation_text'] 

and I get the following error:

TypeError: string indices must be integers

Has anyone experienced the same issue before? Thanks a lot for your help!

>Solution :

The dictionary is the first item of the list a, i.e., you need to access it by using its index, 0:

>>> a = [{'translation_text': 'I love cake.'}]
>>> a[0]
{'translation_text': 'I love cake.'}
>>> a[0]['translation_text']
'I love cake.'
