Lists
Lists are rendered with Python syntax:
%%tap
[]
[1.23, 4.56, 7.89]
[[1, 2], [3, 4]]\( \displaystyle \left[\right] \)
\( \displaystyle \left[ 1.23,\, 4.56,\, 7.89 \right] \)
\( \displaystyle \left[ \left[ 1,\, 2 \right],\, \left[ 3,\, 4 \right] \right] \)
Unpacking is rendered as a union:
%%tap
a = [1, 2]
[4, 5, *a]\( \displaystyle a = \left[ 1,\, 2 \right] \)
\( \displaystyle \left[ 4,\, 5 \right] \cup a = \left[ 4,\, 5 \right] \cup \left[ 1,\, 2 \right] = \left[ 4,\, 5,\, 1,\, 2 \right] \)
Aligning Vertically
If the list is longer than @max_inline_elts, it will be arranged vertically for readability.
config.max_inline_elts5%%tap
[1, 2, 3, 4, 5, 6]
\( \displaystyle
\left[
\begin{array}{c}
1 \\ 2 \\ 3 \\ 4 \\ 5 \\ 6
\end{array}
\right]
\)
As an Array
@show_list_as_array controls the rendering style:
config.show_list_as_arrayFalseIf set to True, lists will be rendered to look like an array, if possible:
%%tap @show_list_as_array=True
[]
[1.23, 4.56, 7.89]
[[1, 2], [3, 4]]\( \displaystyle \left[\right] \)
\( \displaystyle \left[ 1.23,\, 4.56,\, 7.89 \right] \)
\( \displaystyle \left[ \left[ 1,\, 2 \right],\, \left[ 3,\, 4 \right] \right] \)
1D list-arrays can be shown as a row vector by setting @show_1d_as_col=False
%%tap @show_list_as_array=True @show_1d_as_col=False
[1.23, 4.56, 7.89]\( \displaystyle \left[ 1.23,\, 4.56,\, 7.89 \right] \)
@array_delimiter controls the appearance of delimiters used in a list-array. Use "pmatrix" for parentheses and "bmatrix" for square brackets.
config.array_delimiter'bmatrix'%%tap @show_list_as_array=True @array_delimiter="pmatrix"
[]
[1.23, 4.56, 7.89]
[[1, 2], [3, 4]]\( \displaystyle \left[\right] \)
\( \displaystyle \left[ 1.23,\, 4.56,\, 7.89 \right] \)
\( \displaystyle \left[ \left[ 1,\, 2 \right],\, \left[ 3,\, 4 \right] \right] \)
List Element Access
List element access appears as a subscript:
%%tap
v = [1, 2, 3, 4]
v[0] # Single element access
v[:2] # Slice access\( \displaystyle v = \left[ 1,\, 2,\, 3,\, 4 \right] \)
\( \displaystyle v_{\left( 0 \right)} = 1 \)
Single element access
\( \displaystyle v_{\left( : 2 \right)} = \left[ 1,\, 2 \right] \)
Slice access
Whether or not the subscript is enclosed in parentheses is controlled by @wrap_indices:
config.wrap_indicesTrue%%tap @wrap_indices=False
v = [1, 2, 3, 4]
v[0] # Single element access
v[:2] # Slice access\( \displaystyle v = \left[ 1,\, 2,\, 3,\, 4 \right] \)
\( \displaystyle v_{\left( 0 \right)} = 1 \)
Single element access
\( \displaystyle v_{\left( : 2 \right)} = \left[ 1,\, 2 \right] \)
Slice access
List Comprehensions
List comprehensions are rendered like so:
%%tap
a = [1, 2, 3, 4]
x = 3 # x is shadowed by the comprehension scope
[x**2 for x in a if x % 2 == 0]\( \displaystyle a = \left[ 1,\, 2,\, 3,\, 4 \right] \)
\( \displaystyle x = 3 \)
x is shadowed by the comprehension scope
\( \displaystyle \left[\, x^{2} \;\middle|\; x \in a \land x \mathbin{\%} 2 = 0 \,\right] = \left[ 4,\, 16 \right] \)
Tuples
Tuples are rendered with Python syntax:
%%tap
()
(1.23, 4.56, 7.89)
((1, 2), (3, 4))\( \displaystyle \left(\right) \)
\( \displaystyle \left( 1.23,\, 4.56,\, 7.89 \right) \)
\( \displaystyle \left( \left( 1,\, 2 \right),\, \left( 3,\, 4 \right) \right) \)
Unpacking is rendered as a union:
%%tap
a = (1, 2)
(4, 5, *a)\( \displaystyle a = \left( 1,\, 2 \right) \)
\( \displaystyle \left( 4,\, 5 \right) \cup a = \left( 4,\, 5 \right) \cup \left( 1,\, 2 \right) = \left( 4,\, 5,\, 1,\, 2 \right) \)
Aligning Vertically
If the tuple is longer than @max_inline_elts, it will be arranged vertically for readability.
config.max_inline_elts5%%tap
(1, 2, 3, 4, 5, 6)
\( \displaystyle
\left(
\begin{array}{c}
1 \\ 2 \\ 3 \\ 4 \\ 5 \\ 6
\end{array}
\right)
\)
As an Array
@show_tuple_as_array controls the rendering style:
config.show_tuple_as_arrayFalseIf set to True, tuples will be rendered to look like an array, if possible:
%%tap @show_tuple_as_array=True
()
(1.23, 4.56, 7.89)
((1, 2), (3, 4))\( \displaystyle \left(\right) \)
\( \displaystyle \left( 1.23,\, 4.56,\, 7.89 \right) \)
\( \displaystyle \left( \left( 1,\, 2 \right),\, \left( 3,\, 4 \right) \right) \)
1D tuple-arrays can be shown as a row vector by setting @show_1d_as_col=False
%%tap @show_tuple_as_array=True @show_1d_as_col=False
(1.23, 4.56, 7.89)\( \displaystyle \left( 1.23,\, 4.56,\, 7.89 \right) \)
@array_delimiter also controls the appearance of delimiters used in a tuple-array. Use "pmatrix" for parentheses and "bmatrix" for square brackets.
Tuple Element Access
Tuple element access appears as a subscript:
%%tap

v[-1] # Single element access
v[1:3] # Slice access\( \displaystyle v = \left( 1,\, 2,\, 3,\, 4 \right) \)
\( \displaystyle v_{\left( -1 \right)} = 4 \)
Single element access
\( \displaystyle v_{\left( 1 : 3 \right)} = \left( 2,\, 3 \right) \)
Slice access
Whether or not the subscript is enclosed in parentheses is controlled by @wrap_indices.
%%tap @wrap_indices=False
v = (1, 2, 3, 4)
v[-1] # Single element access
v[1:3] # Slice access\( \displaystyle v = \left( 1,\, 2,\, 3,\, 4 \right) \)

Unpacking is rendered as a union:
%%tap
a = {1, 2}
{4, 5, *a}\( \displaystyle a = \left\{ 1,\, 2 \right\} \)
\( \displaystyle \left\{ 4,\, 5 \right\} \cup a = \left\{ 4,\, 5 \right\} \cup \left\{ 1,\, 2 \right\} = \left\{ 1,\, 2,\, 4,\, 5 \right\} \)
Aligning Vertically
