Code:

a=input().split() print(a)

When submitting to the input line '1 2 3'

 Traceback (most recent call last): File "", line 1, in <module> a=input().split() File "<string>", line 1 1 2 3 ^ SyntaxError: invalid syntax

The expression is taken from the example, it should work. What could be the snag?

    In Python 3, everything is fine, in the second one there really is such a problem. Are you using a second python? If so, indicate this in the question (and the tag) so that there will be no misunderstandings later. - Flowneee
  • If an example is from some book, then it is better to put the third python instead of the second one, and then there will be even more inconsistencies in the future - Andreymal

This is not split - this input throws an exception. Why all? Goodness. The documentation says this - input does two things:

1) Reads from stdin.

2) Everything that is read is executed ( eval ).

Accordingly, the string 1 2 3 could not be executed due to incorrect syntax. In Py3, the behavior of input() changed so that people no longer get confused. Use raw_input . Or Python3. And you can also use the six library so that if you suddenly move to another version, your code will not break, because there is no raw_input() function in raw_input() .

    Just replace the input() method with raw_input()
