input（）-行继续符后的意外字符

Question

Ok I've search for this one for quite some time but have not been able to resolve this issue. I am sure that this issue lies with input().

networkPath = input("Drop Path: ")
print("test") # <- will never get here

SyntaxError: unexpected character after line continuation character

Also, if the user puts their input in quotes this error does not occur. Such as seen here: syntaxerror: unexpected character after line continuation character in python

I do not want the user to have to wrap their input in quotes. The reasoning is that they will be putting in long network paths such as: \\oursite.com\\someplace\\global\\Communications\\News\\Sitemap

Now I know you are thinking, "why can't they just wrap in quotes?" The reasoning is that they would be copying and pasting that network path from a generated email.

Thanks in advance!

Edit: I should note that this fails in windows command line and not in pyscripter

Answer 1

The root problem here is almost certainly that you're learning Python 3, but trying to use a Python 2.7 interpreter to do it. Don't do that. Go download Python 3.3 or later and use that.

But if you're actually intentionally trying to use Python 2.7, read on:

I am sure that this issue lies with input().

You're right. As the documentation says, input is:

Equivalent to eval(raw_input(prompt)) .

In other words, whatever the user types in gets passed to eval . Which means it's being evaluated as Python code. And, unless the user happens to type something that's valid Python code (like a string in quotes), you will get a SyntaxError .

The solution here is simple: Don't use input , use raw_input .

(Note that Python 3's input is the same as Python 2's raw_input , and it doesn't have any equivalent to Python 2's input . This is why I believe you're using the wrong Python version.)

Answer 2

Don't use input() for this; use raw_input(). Input() calls eval() on the read-in text, which you neither need or want , and which is responsible for this error.
