Warning[Pe223]: function "AD9833_FreqSet" declared implicitly E:\DD\Core\Src\ad9833.c 32

引用\[1\]:import apriori ''' Traceback (most recent call last): File "C:\Users\Administrator\anaconda3\lib\site-packages\IPython\core\interactiveshell.py", line 3343, in run_code exec(code_obj, self.user_global_ns, self.user_ns) File "<ipython-input-37-a1e44526a1c6>", line 1, in <module> import apriori File "C:\Users\Administrator\anaconda3\lib\site-packages\apriori.py", line 79 print freqSet-conseq,'-->',conseq,'conf:',conf ^ SyntaxError: Missing parentheses in call to 'print'. Did you mean print(freqSet-conseq,'-->',conseq,'conf:',conf)? ''' 。 引用\[2\]:出现此类错误时，应该换导入的方法：SyntaxError: Missing parentheses in call to 'print'. Did you mean print(freqSet-conseq,'-->',conseq,'conf:',conf)? from efficient_apriori import apriori 。

根据引用\[1\]和引用\[2\]的内容，这是一个Python语法错误，缺少了print函数的括号。正确的写法应该是print(freqSet-conseq,'-->',conseq,'conf:',conf)。你可以尝试将代码中的print语句改为正确的写法。

引用\[3\]: 在学习古月老师ROS第四课，启动机器人的键盘控制launch文件时报了这个error，下面是报错的内容： process\[mbot_teleop-1\]: started with pid \[4942\] File "/home/zxf/catkin_ws/src/mbot_teleop/scripts/mbot_teleop.py", line 78 print msg ^ SyntaxError: Missing parentheses in call to 'print'. Did you mean print(msg)? \[mbot_teleop-1\] process has died \[pid 4942, exit code 1, cmd /home/zxf/catkin_ws/src/mbot_teleop/scripts/mbot_teleop.py __name:=mbot_teleop __log:=/home/zxf/.ros/log/4e9341ca-0155-11ec-8ec5-cf95496c0738/mbot_teleop-1.log\]. log file: /home/zxf/.ros/log/4e9341ca-0155-11ec-8ec5-cf95496c0738/mbot_teleop-1*.log 。

根据引用\[3\]的内容，这是一个ROS启动机器人键盘控制launch文件时的错误。错误信息显示在mbot_teleop.py文件的第78行，缺少了print函数的括号。正确的写法应该是print(msg)。你可以尝试将代码中的print语句改为正确的写法。

问题:Warning\[Pe223\]: function "AD9833_FreqSet" declared implicitly E:\DD\Core\Src\ad9833.c 32
回答: 根据你提供的信息，这是一个警告信息，指示在E:\DD\Core\Src\ad9833.c文件的第32行中，函数"AD9833_FreqSet"被隐式声明。这意味着在该文件中没有显式地声明该函数。你可以在该文件中添加函数声明来解决这个警告。
