JoinStrings
Overview¶
The JoinStrings Block takes a list of strings and joins them together into a single string using a configured separator. You can specify the separator to use between the strings (such as a space, comma, or other characters). The resulting string is then output.
This Block is helpful when you need to concatenate a list of strings with a custom separator.

Example(s)¶
Example 1: Join strings with a space separator¶
- Create a
JoinStringsBlock. - Set the
separatorto" ". - Provide the input list:
["apple", "banana", "cherry"]. - The output will be
"apple banana cherry".
Example 2: Join strings with a comma¶
- Create a
JoinStringsBlock. - Set the
separatorto",". - Provide the input list:
["apple", "banana", "cherry"]. - The output will be
"apple,banana,cherry".
Example 3: Join strings without a separator¶
- Set up a
JoinStringsBlock. - Leave the
separatoras an empty string (""). - Provide the input list:
["apple", "banana", "cherry"]. - The output will be
"applebananacherry".
Error Handling¶
- The
JoinStringsBlock expects a list of strings as input. If any item in the list is not a string, it may result in an error or undefined behavior. - If the input list is empty, the Block will output an empty string.
FAQ¶
What happens if the input list is empty?
If the input list is empty, the JoinStrings Block will return an empty string.
Can I use this block to join strings with multi-character separators?
Yes, you can use any string as the separator, including multi-character strings. For example, setting the separator to " - " will join the strings with a hyphen and spaces.
What happens if the input contains non-string items?
The JoinStrings Block expects all items in the list to be strings. If the input contains non-string items, it may raise an error or cause unexpected behavior. Ensure all items are strings before using the Block.
