走了一个不会Python的实习生,来了一个会Python数据分析的实习生,感觉真的天差地别!

走了一个不会Python的实习生,来了一个会Python数据分析的实习生,感觉真的天差地别!
之前带过一个不会Python数据分析的女生，真够头疼的了！让她做数据清洗都得反复折腾，基本的Pandas和Matplotlib用法更是一脸懵，硬生生给我加了不少工作。
现在又新来了一个实习生，丢给他的任务，分分钟搞定不说准确率也很高！无论是用pandas读取CSV、Excel或SQL数据，还是使用pandas处理缺失值（dropna()或fillna()）、去重（drop_duplicates()）、重命名列等操作都不在话下，这感觉真的一个天上一个地上。
其实用Python做数据分析真不难，吃透这些流程，你也能分分钟搞定数据分析工作：
