# Miscellaneous¶

Miscellaneous stuff that doesn’t really fit anywhere else.

sympy.utilities.misc.debug(*args)[source]

Print *args if SYMPY_DEBUG is True, else do nothing.

sympy.utilities.misc.debug_decorator(func)[source]

If SYMPY_DEBUG is True, it will print a nice execution tree with arguments and results of all decorated functions, else do nothing.

sympy.utilities.misc.find_executable(executable, path=None)[source]

Try to find ‘executable’ in the directories listed in ‘path’ (a string listing directories separated by ‘os.pathsep’; defaults to os.environ[‘PATH’]). Returns the complete filename or None if not found

sympy.utilities.misc.rawlines(s)[source]

Return a cut-and-pastable string that, when printed, is equivalent to the input. The string returned is formatted so it can be indented nicely within tests; in some cases it is wrapped in the dedent function which has to be imported from textwrap.

Examples

Note: because there are characters in the examples below that need to be escaped because they are themselves within a triple quoted docstring, expressions below look more complicated than they would be if they were printed in an interpreter window.

>>> from sympy.utilities.misc import rawlines
>>> from sympy import TableForm
>>> s = str(TableForm([[1, 10]], headings=(None, ['a', 'bee'])))
>>> print(rawlines(s)) # the \ appears as \ when printed
(
'a bee\n'
'-----\n'
'1 10 '
)
>>> print(rawlines('''this
... that'''))
dedent('''\
this
that''')

>>> print(rawlines('''this
... that
... '''))
dedent('''\
this
that
''')

>>> s = """this
... is a triple '''
... """
>>> print(rawlines(s))
dedent("""\
this
is a triple '''
""")

>>> print(rawlines('''this
... that
...     '''))
(
'this\n'
'that\n'
'    '
)
