Joins two text strings into one text string. The concatenated string. The joined items can be text, numbers or Boolean values represented as text, or a combination of those items. You can also use a column reference if the column contains appropriate values. If you want to use text strings directly, rather than using a column reference, you must enclose each string in double quotation marks.

Wrangle vs. SQL: This function is part of Wrangle, a proprietary data transformation language. Wrangle is not SQL. For more information, see Wrangle Language. Output: Generates a new array containing a single array listing all of the elements in array1 followed by all elements from array2 in order. Syntax and Arguments. For more information on syntax standards, see Language Documentation Syntax Notes.

Array literal or name of the array column whose elements you want to concatenate together. You can conc atenate together two or more arrays.

Examples Tip: For additional examples, see How-to Guides. This simple example illustrates how the following functions operate on nested data. You can apply the following transforms in the following order. Note that the column names must be different from the transform name, which is a reserved word. For display purposes, the results table has been broken down into three separate sets of columns.

Combines the elements of one array with another, listing all elements of the first array before listing all elements of the second array.

Arrays are referenced by column name or as array literals. This function applies two or more columns of Array type only. To concatenate string values, see Merge Transform.

Duplicate values are not removed from the generated array. Basic Usage Array literal reference example: arrayconcat [["A","B","C"],["C","D","E"]] Output: Generates the following array: ["A","B","C","C","D","E"] Column reference example: arrayconcat [array1,array2] Output: Generates a new array containing a single array listing all of the elements in array1 followed by all elements from array2 in order.

Usage Notes: Required? Example - Simple concat example This simple example illustrates how the following functions operate on nested data. Source: Code formatting has been applied to improve legibility.



Documentation Help Center. Each input argument can be a character array, a cell array of character vectors, or a string array. If any input is a cell array, and none are string arrays, then the result is a cell array of character vectors. For character array inputs, strcat removes trailing ASCII white-space characters: space, tab, vertical tab, newline, carriage return, and form feed. For cell and string array inputs, strcat does not remove trailing white space. Starting in Ra, you can create string arrays using double quotes.

Slowest and doesn't work in Python3: concatenate the items and call dict on the resulting list:. I recommend approach 2 , and I particularly recommend avoiding 1 which also takes up O N extra auxiliary memory for the concatenated list of items temporary data structure. Previous SO question that both of these answers came from is here. You can use the update method to build a new dictionary containing all the items:. Here's a one-liner imports don't count : that can easily be generalized to concatenate N dictionaries:.
