Just like a list, a tuple is also an ordered collection of Python objects. The only difference between a tuple and a list is that tuples are immutable i.e. tuples cannot be modified after it is created. It is represented by a tuple class

3. What are primary sources?
Original records from the past recorded by
people who were:
Involved in the event
Witnessed the event, OR
Knew the persons involved in the event

They give you an idea about what people
alive at the time saw or thought about the
event.

13. Secondary Sources

14. What are secondary sources?
Secondary sources are made at a later time.
They include written information by
historians or others AFTER an event has
taken place.

15. What are secondary sources?
Although they can be useful and reliable,
they cannot reflect what people who lived at
the time thought or felt about the event.
But they can represent a more fair account
of the event because they can include more
than one point of view, or may include
information that was unavailable at the time
of the event.

16. Examples of secondary sources:
Textbooks, biographies,
histories, newspaper report
by someone who was not
present

Charts, graphs, or images
created AFTER the time
period.
