为什么运行这个代码会出现EOL while scanning string literal

这个异常通常是由于字符串中的引号没有成对出现导致的。例如，如果你在字符串中使用单引号，但是在字符串中也包含单引号，则会导致解释器无法正确识别字符串的结束位置，从而抛出EOL while scanning string literal异常。解决这个问题的方法是在字符串中使用双引号或者转义字符来表示包含的引号。例如：

print('It's a beautiful day') # 这行代码会抛出EOL while scanning string literal异常
print("It's a beautiful day") # 这行代码会正确输出：It's a beautiful day
print('It\'s a beautiful day') # 这行代码也会正确输出：It's a beautiful day

EOL while scanning string literal

这是一个语法错误，意思是在扫描字符串字面量时遇到了行结束符。通常是因为字符串字面量未被正确地闭合，例如：

s = "hello

这里缺少了一个双引号来闭合字符串，所以会出现这个错误。为了解决这个错误，需要在字符串的末尾加上一个双引号：

s = "hello"

另外还可能是因为多加了一个双引号，或者使用了一个不能识别的转义字符，所以也会出现这个错误

字符串长这样 : "hello\"

这样就会出现 eol while scanning string literal 的错误。

eol while scanning string literal

This error occurs when there is an end-of-line character within a string literal, which is not valid syntax in most programming languages. To fix this error, you need to either remove the end-of-line character or escape it using the appropriate escape sequence depending on the language you are using.

For example, in Python, you can use the backslash (\) character to escape an end-of-line character within a string:

my_string = "This is a string \
             with an end-of-line character"

In JavaScript, you can use the backslash (\) character to escape an end-of-line character within a string:

var myString = "This is a string \
               with an end-of-line character";

Make sure to check the syntax rules of the programming language you are using to ensure that your code is valid.
