您没有"在行尾放置a 。
"""如果要执行此操作，请使用：
""" a very long string ......
....that can span multiple lines
"""
You are not putting a " before the end of the line.
Use """ if you want to do this:
""" a very long string ......
....that can span multiple lines
"""

我遇到了这个问题-我最终弄清楚了原因是我\在字符串中包含了字符。如果您有任何一个，请与他们“转义” \\，它应该可以正常工作。
I had this problem – I eventually worked out that the reason was that I’d included \ characters in the string. If you have any of these, “escape” them with \\ and it should work fine.

（假设您的字符串中没有/想要换行…）
这串真的多久了？
我怀疑从文件或从命令行读取的行的长度是有限制的，并且由于行的结尾被解析器截断，因此会看到类似s1="some very long string..........（不带结尾"）的内容，从而引发解析错误？
您可以通过在源代码中转义换行符，将长行分成多行：
s1="some very long string.....\
...\
...."
(Assuming you don’t have/want line breaks in your string…)
How long is this string really?
I suspect there is a limit to how long a line read from a file or from the commandline can be, and because the end of the line gets choped off the parser sees something like s1="some very long string.......... (without an ending ") and thus throws a parsing error?
You can split long lines up in multiple lines by escaping linebreaks in your source like this:
s1="some very long string.....\
...\
...."

在我的情况下，我\r\n在单引号中包含字典字符串。我取代的所有实例\r与\\r和\n与\\n它固定我的问题，正确地返回在eval’ed字典逃脱换行符。
ast.literal_eval(my_str.replace('\r','\\r').replace('\n','\\n'))
.....
In my situation, I had \r\n in my single-quoted dictionary strings. I replaced all instances of \r with \\r and \n with \\n and it fixed my issue, properly returning escaped line breaks in the eval’ed dict.
ast.literal_eval(my_str.replace('\r','\\r').replace('\n','\\n'))
.....

我遇到了类似的问题。我有一个包含Windows中文件夹路径的字符串，例如C:\Users\，问题是\转义字符，因此要在字符串中使用它，您需要再添加一个\。
不正确： C:\Users\
正确： C:\\\Users\\\
I faced a similar problem. I had a string which contained path to a folder in Windows e.g. C:\Users\ The problem is that \ is an escape character and so in order to use it in strings you need to add one more \.
Incorrect: C:\Users\
Correct: C:\\\Users\\\

我也有这个问题，尽管这里有答案，但我想在/不应该有空白的地方对此做一个重要

我也有此确切的错误消息，对我来说，此问题已通过添加“ \”来解决
事实证明，我的长字符串在结尾处被分解成大约八行，并带有“ \”，但在一行上缺少“ \”。
Python IDLE没有指定此错误所在的行号，但是它以红色突出显示了完全正确的变量赋值语句，这使我不满意。实际变形的字符串语句（多行长为“ \”）与突出显示的语句相邻。也许这会帮助别人。
I also had this exact error message, for me the problem was fixed by adding an ” \”
It turns out that my long string, broken into about eight lines with ” \” at the very end, was missing a ” \” on one line.
Python IDLE didn’t specify a line number that this error was on, but it red-highlighted a totally correct variable assignment statement, throwing me off. The actual misshapen string statement (multiple lines long with ” \”) was adjacent to the statement being highlighted. Maybe this will help someone else.

就我而言，我使用Windows，因此必须使用双引号而不是单引号。
C:\Users\Dr. Printer>python -mtimeit -s"a = 0"
100000000 loops, best of 3: 0.011 usec per loop
In my case, I use Windows so I have to use double quotes instead of single.
C:\Users\Dr. Printer>python -mtimeit -s"a = 0"
100000000 loops, best of 3: 0.011 usec per loop

我在postgresql函数中遇到此错误。我有一个较长的SQL，使用\分成多行，以提高可读性。但是，这就是问题所在。我删除了所有内容，并将它们放在一行中以解决此问题。我正在使用pgadmin III。
I was getting this error in postgresql function. I had a long SQL which I broke into multiple lines with \ for better readability. However, that was the problem. I removed all and made them in one line to fix the issue. I was using pgadmin III.

就Mac OS X而言，我有以下陈述：
model.export_srcpkg(platform, toolchain, 'mymodel_pkg.zip', 'mymodel.dylib’)
我收到错误：
File "<stdin>", line 1
model.export_srcpkg(platform, toolchain, 'mymodel_pkg.zip', 'mymodel.dylib’)
^
SyntaxError: EOL while scanning string literal
在我更改为：
model.export_srcpkg(platform, toolchain, "mymodel_pkg.zip", "mymodel.dylib")
有效…

您可以尝试以下方法：
s = r'long\annoying\path'
You can try this:
s = r'long\annoying\path'

您variable(s1)跨多行。为了做到这一点（即您希望您的字符串跨越多行），必须使用三引号（“”“）。
s1="""some very long
string............"""
Your variable(s1) spans multiple lines. In order to do this (i.e you want your string to span multiple lines), you have to use triple quotes(“””).
s1="""some very long
string............"""

在这种情况下，三个单引号或三个双引号都可以使用！例如：
"""Parameters:
...Type something.....
.....finishing statement"""
要么
'''Parameters:
...Type something.....
.....finishing statement'''
In this case, three single quotations or three double quotations both will work!
For example:
"""Parameters:
...Type something.....
.....finishing statement"""
OR
'''Parameters:
...Type something.....
.....finishing statement'''

以前的大多数答案都是正确的，我的答案与aaronasterling非常相似，您也可以用3个单引号s1 =”’一些很长的字符串………”’
Most previous answers are correct and my answer is very similar to aaronasterling, you could also do 3 single quotations
s1=”’some very long string…………”’

访问任何硬盘目录时，我都遇到了同样的问题。然后我以这种方式解决了。
import os
os.startfile("D:\folder_name\file_name") #running shortcut
os.startfile("F:") #accessing directory
上图显示了错误和已解决的输出。
I had faced the same problem while accessing any hard drive directory.
Then I solved it in this way.
import os
os.startfile("D:\folder_name\file_name") #running shortcut
os.startfile("F:") #accessing directory
The picture above shows an error and resolved output.
