def as_apply(func, *args, **kwargs):

Return object as APPLY expression (function call, constructor, etc.)

def as_array(obj):

Return object as ARRAY expression (array constant).

def as_complex(real, imag=0):

Return object as COMPLEX expression (complex literal constant).

def as_deref(expr):

Return object as dereferencing expression.

def as_eq(left, right):

Undocumented

def as_expr(obj):

Convert non-Expr objects to Expr objects.

def as_factors(obj):

Return expression as FACTORS expression.

def as_ge(left, right):

Undocumented

def as_gt(left, right):

Undocumented

def as_integer(obj, kind=4):

Return object as INTEGER constant.

def as_le(left, right):

Undocumented

def as_lt(left, right):

Undocumented

Undocumented

def as_number(obj, kind=4):

Return object as INTEGER or REAL constant.

def as_numer_denom(obj):

Return expression as numer-denom pair.

def as_real(obj, kind=4):

Return object as REAL constant.

def as_ref(expr):

Return object as referencing expression.

def as_string(obj, kind=1):

Return object as STRING expression (string literal constant).

def as_symbol(obj):

Return object as SYMBOL expression (variable or unparsed expression).

def replace_parenthesis(s):

Replace substrings of input that are enclosed in parenthesis.
