How to use sympy.latex() and sympy.sympify() to produce unevaluated parameterized expression fr'\frac{{3}}{{{i}}}'?

from IPython.display import display,  Math
import sympy as sym
for i in range(-1,2):
    display(Math(fr'\frac{{3}}{{{i}}}'))
for i in range(-1,2):
    display(Math(sym.latex(sym.sympify(f'3/{i}'))))

Edit

The objective is to generate:

fr'\frac{{3}}{{{-1}}}'
fr'\frac{{3}}{{{0}}}'
fr'\frac{{3}}{{{1}}}'

with sympy.latex() and sympy.sympify() (or its variant).

CodePudding user response：

Just set evaluate=False into sympify:

for i in range(-1,2):
    display(Math(sym.latex(sym.sympify(f'3/{i}', evaluate=False))))
