Working with Lists and tuples

问题

My data looks like:

X=[1,2,3,4]

But I need it to look like:

Y=[(1,2,3,4)]

How does one do this in python?

回答1:

Try this:

l = [1,2,3,4]
l2 = [tuple(l)]

回答2:

To do this is simple

>>> X = [1,2,3,4]
>>> [tuple(X)]
[(1, 2, 3, 4)]

Convert X to a tuple and wrap it in a list. This is only one of probably many ways to do this. It doesn't seem like a very useful thing, so if you could explain why you want to do this, we may be able to suggest some more useful code for you.
