This module has no docstring.
Create a new memoryview object which references the given object.
cast(...) Cast a memoryview to a new format or shape.
hex(...)
Return the data in the buffer as a str of hexadecimal numbers.
sep
An optional single character or byte to separate hex bytes.
bytes_per_sep
How many bytes between separators. Positive values count from the
right, negative values count from the left.
Example:
>>> value = memoryview(b'\xb9\x01\xef')
>>> value.hex()
'b901ef'
>>> value.hex(':')
'b9:01:ef'
>>> value.hex(':', 2)
'b9:01ef'
>>> value.hex(':', -2)
'b901:ef'
release(self, /) Release the underlying buffer exposed by the memoryview object.
tobytes(self, /, order='C')
Return the data in the buffer as a byte string.
Order can be {'C', 'F', 'A'}. When order is 'C' or 'F', the data of the
original array is converted to C or Fortran order. For contiguous views,
'A' returns an exact copy of the physical memory. In particular, in-memory
Fortran order is preserved. For non-contiguous views, the data is converted
to C first. order=None is the same as order='C'.
tolist(self, /) Return the data in the buffer as a list of elements.
toreadonly(self, /) Return a readonly version of the memoryview.
c_contiguous = <attribute 'c_contiguous' of 'memoryview' objects> A bool indicating whether the memory is C contiguous.
contiguous = <attribute 'contiguous' of 'memoryview' objects> A bool indicating whether the memory is contiguous.
f_contiguous = <attribute 'f_contiguous' of 'memoryview' objects> A bool indicating whether the memory is Fortran contiguous.
format = <attribute 'format' of 'memoryview' objects> A string containing the format (in struct module style) for each element in the view.
itemsize = <attribute 'itemsize' of 'memoryview' objects> The size in bytes of each element of the memoryview.
nbytes = <attribute 'nbytes' of 'memoryview' objects> The amount of space in bytes that the array would use in a contiguous representation.
ndim = <attribute 'ndim' of 'memoryview' objects> An integer indicating how many dimensions of a multi-dimensional array the memory represents.
obj = <attribute 'obj' of 'memoryview' objects> The underlying object of the memoryview.
readonly = <attribute 'readonly' of 'memoryview' objects> A bool indicating whether the memory is read only.
shape = <attribute 'shape' of 'memoryview' objects> A tuple of ndim integers giving the shape of the memory as an N-dimensional array.
strides = <attribute 'strides' of 'memoryview' objects> A tuple of ndim integers giving the size in bytes to access each element for each dimension of the array.
suboffsets = <attribute 'suboffsets' of 'memoryview' objects> A tuple of integers used internally for PIL-style arrays.
SQLite database connection object.
backup(self, /, target, *, pages=-1, progress=None, name='main', sleep=0.25) Makes a backup of the database.
close(self, /) Close the database connection. Any pending transaction is not committed implicitly.
commit(self, /) Commit any pending transaction to the database. If there is no open transaction, this method is a no-op.
create_aggregate(self, /, name, n_arg, aggregate_class) Creates a new aggregate.
create_collation(self, name, callback, /) Creates a collation function.
create_function(self, /, name, narg, func, *, deterministic=False) Creates a new function.
cursor(...) Return a cursor for the connection.

executescript(self, sql_script, /) Executes multiple SQL statements at once.
interrupt(self, /) Abort any pending database operation.
iterdump(self, /) Returns iterator to the dump of the database in an SQL text format.
load_extension(self, name, /) Load SQLite extension module.
rollback(self, /) Roll back to the start of any pending transaction. If there is no open transaction, this method is a no-op.
set_authorizer(self, /, authorizer_callback) Sets authorizer callback.
set_progress_handler(self, /, progress_handler, n) Sets progress handler callback.
set_trace_callback(self, /, trace_callback) Sets a trace callback called for each SQL statement (passed as unicode).
