Expression of type ExprTuple

from the theory of proveit.numbers.multiplication

proveit.defaults.automation = False # This will speed things up.
proveit.defaults.inline_pngs = False # Makes files smaller.

# import Expression classes needed to build the expression

# build up the expression from sub-expressions
expr = ExprTuple(InSet(a, Natural), InSet(x, Natural), InSet(y, Natural), NotEquals(x, y), NotEquals(a, zero))

expr:

# check that the built expression is the same as the stored expression
assert expr == stored_expr
assert expr._style_id == stored_expr._style_id
print("Passed sanity check: expr matches stored_expr")

Passed sanity check: expr matches stored_expr

# Show the LaTeX representation of the expression for convenience if you need it.
print(stored_expr.latex())
