将元组列表放入一个元组中，以逗号分隔导出到 SQL

Question

I am hitting and looping through an API to collect various data into a variable called data . If I do print(data) I get the following:

('1111', 11, 'Test1', '2020-16-09', '123')
('2222', 22, 'Test2', '2020-16-09', '234')
('3333', 33, 'Test3', '2020-16-09', '345')

When I do print(type(data)) I get the following:

<class 'tuple'>
<class 'tuple'>
<class 'tuple'>

I need to put these tuples into one tuple separating each with a comma to look something like the below.

( 
    ('1111', 11, 'Test1', '2020-16-09', '123'),
    ('2222', 22, 'Test2', '2020-16-09', '234'),
    ('3333', 33, 'Test3', '2020-16-09', '345') 
)

This it to allow me to export the data into SQL using cursor.executemany

Answer 1

Let's say you have a function api(x) that returns you the tuple for input x , and you know all the x you need to query, which is from a list X=[x1, x2, ...] , then you can get a tuple of tuple by this:

tuple_of_tuples = tuple(api(x) for x in X)

but in the case of cursor.executemany() , many database library accepts an iterable as input, in that case, you can use a generator instead, which saves you memory in keeping all tuples:

generator_of_tuples = (api(x) for x in X)

Thanks everyone for your help, after doing some more digging around this is how I managed to get the data how I needed it.

jsondata = (multiple tuples) #my data from looping an API
    if b == 0: #b is my loop through the API
        finaldata = (jsondata,)
    else:
        finaldata = (jsondata,) + finaldata
