How to use len() and split() to combine first few strings while keeping the last string alone in a l-CodePudding

From ['The', 'range', 'of', 'number', 'is', 'to'] to ['The range of number is', 'to']

How to combine the first 5th strings into one string while keeping the 6th one alone?

With len() and split() method.

CodePudding user response：

Well, not exactly with those methods, since you don't need them.

>>> x = ['The', 'range', 'of', 'number', 'is', 'to']
>>> [" ".join(x[:-1])]   [x[-1]]
['The range of number is', 'to']

The idea is to join all strings but the last with a space, then append the last word as a list.

Another option would be to use join and rsplit, which is arguably easier to read:

>>> " ".join(x).rsplit(" ", 1)
['The range of number is', 'to']

CodePudding user response：

you can do this:

>>> var = ['The', 'range', 'of', 'number', 'is', 'to']
>>> [" ".join(var[:5]), " ".join(var[5:])]
['The range of number is', 'to']
