SyntaxError: Missing parentheses in call to 'print'. Did you mean print("[DEBUG COMMAND] "+cmd)?

这个SyntaxError是一个Python编程错误,提示说在打印语句中缺少了圆括号。原始的意图可能是调用`print`函数并传递一个字符串拼接表达式,其中包含了调试命令`[DEBUG COMMAND]`加上变量`cmd`。正确的语法应该是这样的:
```python
print("[DEBUG COMMAND] " + cmd)
```
程序员可能忘记了在`print`之后添加括号,导致解析器无法理解这是一个完整的调用。修复这个问题后,程序应该能正常打印出调试消息。
如果代码原本看起来像这样:
```python
print "[DEBUG COMMAND] " + cmd
```
那么需要修改成:
```python
print("[DEBUG COMMAND] " + cmd)
```
