Given a list of tuples or FrameSummary objects as returned by
extract_tb() or extract_stack(), return a list of strings ready
for printing.
Each string in the resulting list corresponds to the item with the
same index in the argument list. Each string ends in a newline;
the strings may contain internal newlines as well, for those items
whose source text line is not None.

'file' should be an open file or file-like object with a write()
method.

Return a StackSummary object representing a list of
pre-processed entries from traceback.
This is useful for alternate formatting of stack traces. If
'limit' is omitted or None, all entries are extracted. A
pre-processed stack trace entry is a FrameSummary object
containing attributes filename, lineno, name, and line
representing the information that is usually printed for a stack
trace. The line is a string with leading and trailing
whitespace stripped; if the source is not available it is None.

This differs from print_tb() in the following ways: (1) if
traceback is not None, it prints a header "Traceback (most recent
call last):"; (2) it prints the exception type and value after the
stack trace; (3) if type is SyntaxError and value has the
appropriate format, it prints the line where the syntax error
occurred with a caret on the next line indicating the approximate
position of the error.

The arguments have the same meaning as the corresponding arguments
to print_exception(). The return value is a list of strings, each
ending in a newline and some containing internal newlines. When
these lines are concatenated and printed, exactly the same text is
printed as does print_exception().

The arguments are the exception type and value such as given by
sys.last_type and sys.last_value. The return value is a list of
strings, each ending in a newline.
Normally, the list contains a single string; however, for
SyntaxError exceptions, it contains several lines that (when
printed) display detailed information about where the syntax
error occurred.
The message indicating which exception occurred is always the last
string in the list.

Returns a list of strings ready for printing. Each string in the
resulting list corresponds to a single frame from the stack.
Each string ends in a newline; the strings may contain internal
newlines as well, for those items with source text lines.
For long sequences of the same frame and line, the first few
repetitions are shown, followed by a summary line stating the exact
number of further repetitions.

The traceback module captures enough attributes from the original exception
to this intermediary form to ensure that no references are held, while
still being able to fully print or format it.
Use `from_exception` to create TracebackException instances from exception
objects, or the constructor to create TracebackException instances from
individual components.
- :attr:`__cause__` A TracebackException of the original *__cause__*.
- :attr:`__context__` A TracebackException of the original *__context__*.
- :attr:`__suppress_context__` The *__suppress_context__* value from the
original exception.
- :attr:`stack` A `StackSummary` representing the traceback.
- :attr:`exc_type` The class of the original traceback.
- :attr:`filename` For syntax errors - the filename where the error
occurred.
- :attr:`lineno` For syntax errors - the linenumber where the error
occurred.
- :attr:`text` For syntax errors - the text where the error
occurred.
- :attr:`offset` For syntax errors - the offset into the text where the
error occurred.
- :attr:`msg` For syntax errors - the compiler error message.
