Expression of type ExprTuple

from the theory of proveit.core_expr_types.tuples

import proveit

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
from proveit import ExprTuple, j
from proveit.numbers import Add, Exp, e, four, three, two

# build up the expression from sub-expressions
expr = ExprTuple(Exp(e, Add(two, j)), Exp(e, Add(three, j)), Exp(e, Add(four, j)))

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())

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',)
