How to split a string in Python by 2 or 3, etc [duplicate]
2024/11/18 22:46:08
Does anyone know if it's possible in python to split a string, not necessarily by a space or commas, but just by every other entry in the string? or every 3rd or 4th etc.
For example if I had "12345678" as my string, is there a way to split it into "12", "34", "56", 78"?
Answer
You can use list comprehension:
>>> x = "123456789"
>>> [x[i : i + 2] for i in range(0, len(x), 2)]
['12', '34', '56', '78', '9']
