报错:SyntaxError: unexpected character after line continuation character

引用\[1\]中的代码报错是因为在`os.chdir()`函数中使用了`\`作为路径分隔符,但是`\`在Python中是转义字符,所以需要使用两个`\`来表示一个`\`。正确的写法应该是`os.chdir(time_year + "\\" + time_month + "\\" + time_day)`。
引用\[2\]中的代码报错是因为在`train_test_split()`函数的参数传递过程中使用了`\`作为换行符,但是在`\`后面不能有其他字符,比如空格或者注释。所以需要删除`\`后面的空格或注释。正确的写法应该是:
```
cancer_data_train, cancer_data_test, \
cancer_target_train, cancer_target_test = \
train_test_split(cancer_data, cancer_target, \
test_size=0.2, random_state=42)
```
引用\[3\]中的代码报错是因为在`os.chdir()`函数中使用了`\`作为路径分隔符,但是`\`在Python中是转义字符,所以需要使用两个`\`来表示一个`\`。正确的写法应该是`os.chdir(time_year + "\\" + time_month + "\\" + time_day)`。
所以,报错`SyntaxError: unexpected character after line continuation character`是因为在使用`\`作为路径分隔符时没有正确处理转义字符的问题。
