Question

Answer 1

Use list comprehension. This assumes your tuple is stored in the variable tuple_list .

arr = [i['content'] for i in tuple_list]

Answer 2

Assuming every element is a dictionary with a single key that is always 'content' :

t = ({'content': 'home'}, {'content': 'home2'})
values_list = [d['content"] for d in t]

Read up on python iterators, list comprehensions and tuple and dict datatypes.

Answer 3

The @Bianconi answer is the correct way. But another way for you(beginner) can be:

new_list=[] #new variable list
tuple_list=({'content': 'home'}, {'content': 'home2'}) #your data

# a for loop that read the data from tuple_list and put it into new_list. 
for item in tuple_list:
    new_list.append(item['content'])
print new_list

Hope this helps.
