Is there a way to split a string by every nth separator in Python?

Question

For example, if I had the following string: "this-is-a-string" Could I split it by every 2nd "-" rather than every "-" so that it returns two values ("this-is" and "a-string") rather than returning four?

Accepted Answer

Here’s another solution:

```
span = 2
words = "this-is-a-string".split("-")
print ["-".join(words[i:i+span]) for i in range(0, len(words), span)]
```
