Does DolphinDB have an equivalent method to Python join?
Question:
In Python, I can join all elements into a string separated by a string separator with method join().
>>> ','.join(["{}D".format(i) for i in range(1,6)])
'1D,2D,3D,4D,5D'
How can I implement the function equivalent to join in DolphinDB?
Answers:
You may try function concat to form a string. The equivalent function can be implemented with the following script:
concat(string(1..5) + "D", ',')
The output is
1D,2D,3D,4D,5D
