while scanning string literal
"while scanning string literal" 的意思是在扫描字符串字面值时出现了错误。这通常是因为字符串中包含了不合法的字符或者缺少了引号等标点符号。需要检查字符串的语法是否正确,以解决这个问题。
EOL while scanning string literal
This error occurs when there is an unfinished or unclosed string literal in the code. A string literal is a sequence of characters enclosed in quotes (either single or double quotes).
For example, the following code will result in this error:
```
print('Hello, world!)
```
This is because the string literal 'Hello, world!' is not closed with a closing quote. To fix this, we need to add a closing quote:
```
print('Hello, world!')
```
Another common reason for this error is when there is a line break or a special character (like a tab or a newline) within the string literal that is not properly escaped.
For example:
```
print('Hello,
world!')
```
This will result in the same error because the string literal 'Hello,' is not properly closed before the line break. To fix this, we can either use a backslash to escape the line break:
```
print('Hello, \
world!')
```
Or we can use triple quotes to create a multi-line string:
```
print('''Hello,
world!''')
```
