分析下面代码,写出其输出结果。 marks = {'English': 80, 'Math': 90, 'Science': 95} for k, v in marks.items(): print(k, v, sep= ':', end= ' ') # ( 5 ) 写出前面部分代码的控制台输出结果 print(list(sorted(marks.keys())))

代码的输出结果如下:
```
English:80 Math:90 Science:95 ['English', 'Math', 'Science']
```
代码首先定义了一个字典 `marks`,其中包含了英语、数学和科学三门课程的成绩。然后使用 `for` 循环遍历字典 `marks`,并分别将课程名称和成绩打印输出,两者之间使用冒号 `:` 连接。
输出结果为:
```
English:80 Math:90 Science:95
```
接下来,代码使用 `list` 函数将字典 `marks` 中的所有键转换为列表,并将其传递给 `sorted` 函数进行排序。最后将排序后的列表打印输出。
输出结果为:
```
['English', 'Math', 'Science']
```
综上,代码的输出结果为:
```
English:80 Math:90 Science:95 ['English', 'Math', 'Science']
```

Error: unexpected symbol in: " data = a addOverall"
This error is likely due to a missing operator or a syntax error in the code. Without more context or information about the code, it is difficult to determine the exact cause of the error. However, here are a few possible solutions or suggestions:
- Check for any missing or misplaced operators, such as commas, parentheses, brackets, or quotation marks.
- Make sure that the code is properly formatted and indented, to help identify any syntax errors or mismatches.
- Verify that all variables and functions are properly defined and initialized before they are used.
- Consider using a code editor or IDE that provides syntax highlighting or error checking features to help identify and fix errors more easily.
- If the error persists, try to isolate the problematic code and run it separately to see if the error message provides more specific information.
