Expression of type ExprTuple

from the theory of proveit.logic.booleans.disjunction

import proveit
# Automation is not needed when building an expression:
proveit.defaults.automation = False # This will speed things up.
proveit.defaults.inline_pngs = False # Makes files smaller.
%load_expr # Load the stored expression as 'stored_expr'
# import Expression classes needed to build the expression
from proveit import A, B, C, ExprTuple
from proveit.logic import Boolean, Implies, InSet, Or

# build up the expression from sub-expressions
expr = ExprTuple(InSet(A, Boolean), InSet(B, Boolean), InSet(C, Boolean), Or(A, B), Implies(A, C), Implies(B, C))

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())

\left(A \in \mathbb{B}, B \in \mathbb{B}, C \in \mathbb{B}, A \lor B, A \Rightarrow C, B \Rightarrow C\right)

name	description	default	current value	related methods
wrap_positions	position(s) at which wrapping is to occur; 'n' is after the nth comma.	()	()	('with_wrapping_at',)
justification	if any wrap positions are set, justify to the 'left', 'center', or 'right'	left	left	('with_justification',)
