Fatal Python error: Cannot recover from stack overflow.
Publicado por HDB PROGRAMMING (2 intervenciones) el 17/09/2020 20:44:23
Yo estoy haciendo una especie de intérprete en Python que toma fórmulas matemáticas (por ahora muy básicas) y he avanzado bastante, pero cuando arranco el archivo main.py me tira el error Fatal Python error: Cannot recover from stack overflow. Aquí van los códigos:
main.py:
mods/mlang.py:
test.math (fichero de prueba):
Se arranca con python main.py test.math o en vez de python, python3 pero siempre ejecutar con python 3. Muchas gracias de antemano.

Se arranca con python main.py test.math o en vez de python, python3 pero siempre ejecutar con python 3. Muchas gracias de antemano.
