If you are using the Jupyter notebook you can run
from sympy import init_session
init_session(auto_int_to_Integer=True)
This also works in IPython in the terminal, or you can use isympy -i.
This will automatically wrap integer literals with Integer() so that
1/2 produces Integer(1)/Integer(2).
Just be aware that this could
break non-SymPy things if they don't work properly with Integer, for
example, numpy will create arrays with dtype=object when passed
Integer.
Couldn't that be made a lot more specific and therefore less risky?
Looking for <integer>/<integer> and replacing it with what you describe
- or indeed with Rational(<integer>,<integer>) would be a lot less
likely to disturb Python code.
If the issue is only for copy-pasting, I would just use sympify() to
convert the input as a string.
Sorry, that was a typo - I mean to write Rational(3,2)!
