Math

➕ Add

id numpy_add · Math · Python export: yes

Element-wise a + b (np.add), with NumPy broadcasting. Outputs a DataFrame.

Inputs

Port	Type	Description
a	ndarray | DataFrame | number	Left operand.
b	ndarray | DataFrame | number	Right operand.

Outputs

Port	Type	Description
sum	DataFrame	a + b.

📐 Arange

id numpy_arange · Math · Python export: yes

Evenly spaced values from start up to (not including) stop — np.arange. Each bound can be typed in or wired from another node.

Inputs

Port	Type	Description
start	float	First value (overrides Start).
stop	float	End value, exclusive (overrides Stop).
step	float	Spacing between values (overrides Step).

Outputs

Port	Type	Description
array	ndarray	1-D float array of evenly spaced values.

Fields

Field	Type	Default	Choices
Start	float	0
Stop	float	10
Step	float	1

➗ Divide

id numpy_divide · Math · Python export: yes

Element-wise a / b (np.divide), with NumPy broadcasting. Division by zero gives inf/nan rather than an error.

Inputs

Port	Type	Description
a	ndarray | DataFrame | number	Numerator.
b	ndarray | DataFrame | number	Denominator.

Outputs

Port	Type	Description
quotient	ndarray	a / b, element-wise (true division).

✖️ Multiply

id numpy_multiply · Math · Python export: yes

Element-wise a * b (np.multiply), with NumPy broadcasting. This is NOT matrix multiplication.

Inputs

Port	Type	Description
a	ndarray | DataFrame | number	Left operand.
b	ndarray | DataFrame | number	Right operand.

Outputs

Port	Type	Description
product	ndarray	a * b, element-wise.

🧱 Reshape

id numpy_reshape · Math · Python export: yes

Reshape an array to the comma-separated shape typed in the field (e.g. 2,3 or 4,1,1). The total number of elements must match. To take the shape from another node, use the Array "Reshape" node.

Inputs

Port	Type	Description
array	ndarray | DataFrame | list	Array to reshape.

Outputs

Port	Type	Description
reshaped	ndarray	The reshaped array.

Fields

Field	Type	Default	Choices
Shape	text	2,2

🗜️ Squeeze

id numpy_squeeze · Math · Python export: yes

Remove length-1 axes from an array (np.squeeze), e.g. shape (1, 3, 1) becomes (3,).

Inputs

Port	Type	Description
array	ndarray | DataFrame | list	Array to squeeze.

Outputs

Port	Type	Description
squeezed	ndarray	Array with size-1 axes removed.

➖ Subtract

id numpy_subtract · Math · Python export: yes

Element-wise a - b (np.subtract), with NumPy broadcasting.

Inputs

Port	Type	Description
a	ndarray | DataFrame | number	Left operand.
b	ndarray | DataFrame | number	Right operand.

Outputs

Port	Type	Description
difference	ndarray	a - b.

Text

🔗 Join

id string_join · Text · Python export: yes

Join a list into one string, putting the separator between items. Items that aren't text are converted with str().

Inputs

Port	Type	Description
items	list	The items to join (e.g. from Split or a List node).
sep	str	Text placed between items (overrides the Separator field). Overrides the Separator field when connected.

Outputs

Port	Type	Description
text	str	The joined string.

Fields

Field	Type	Default	Choices
Separator	text	,

🔡 Lowercase

id lowercase · Text · Python export: yes

Convert text to lower case.

Inputs

Port	Type	Description
text	str	Text to operate on (overrides the Text field). Overrides the Text field when connected.

Outputs

Port	Type	Description
text	str	The lower-cased text.

Fields

Field	Type	Default	Choices
Text	text

🔁 Replace

id string_replace · Text · Python export: yes

Replace every occurrence of one piece of text with another (case-sensitive). Set 'Max replacements' to a positive number to limit how many are changed; -1 replaces all. An empty 'Find' leaves the text unchanged.

Inputs

Port	Type	Description
text	str	Text to operate on (overrides the Text field). Overrides the Text field when connected.
old	str	Text to look for (overrides the Find field). Overrides the Find field when connected.
new	str	Text to put in its place (overrides the Replace with field). Overrides the Replace with field when connected.

Outputs

Port	Type	Description
text	str	The text with replacements applied.

Fields

Field	Type	Default	Choices
Text	text
Find	text
Replace with	text
Max replacements (-1 = all)	int	-1

🪓 Split

id string_split · Text · Python export: yes

Split text into a list of strings. Leave 'Separator' blank to split on any whitespace (spaces, tabs, line breaks) and drop empty items; with a separator, splits exactly on it. 'Max splits' of -1 means no limit.

Inputs

Port	Type	Description
text	str	Text to operate on (overrides the Text field). Overrides the Text field when connected.
sep	str	Separator; blank = any whitespace (overrides the field). Overrides the Separator field when connected.

Outputs

Port	Type	Description
parts	list	The pieces, as a list of strings.

Fields

Field	Type	Default	Choices
Text	text
Separator	text	,
Max splits (-1 = no limit)	int	-1

✂️ Strip

id string_strip · Text · Python export: yes

Remove characters from both ends of the text. Leave 'Characters' blank to trim whitespace (spaces, tabs, line breaks); otherwise every character listed is trimmed.
