More specific parsing error?

[Amit Saha]

Hello,

Consider the following:

>>> expr=input('Enter a mathematical expression: ')

Enter a mathematical expression: x**2 + 3x + x**3 + 2x

>>> expr = sympify(expr)

Traceback (most recent call last):

File "<pyshell#146>", line 1, in <module>

expr = sympify(expr)

File "/usr/lib/python3.3/site-packages/sympy/core/sympify.py", line
180, in sympify

raise SympifyError('could not parse %r' % a)

sympy.core.sympify.SympifyError: SympifyError: "could not parse 'x**2
+ 3x + x**3 + 2x'"


Is it possible to get a more specific error message here? Like which
of the terms are invalid, for example?

Thanks,
Amit.

Try using parse_expr from sympy.parsing.sympy_parser.
