数据分析全套工具｜50 个必备Python库合集

刚开始学Python数据分析时，我也犯过一个很典型的错误：看到什么库火就装什么，Pandas、NumPy、Matplotlib、Scikit-learn全部塞进环境里，结果真正拿到数据后，还是不知道应该先用哪个。
后来做的项目多了才发现，Python库并不是学得越多越好，关键是要知道它们分别解决什么问题。处理Excel和CSV，可以用Pandas、OpenPyXL；面对大体量数据，可以了解Polars、Dask；需要画图时，再从Matplotlib、Seaborn、Plotly和Pyecharts中选择；涉及分类、回归和聚类，则会用到Scikit-learn、XGBoost等建模工具。#数据分析 #python数据分析 #库#数据分析师#Python
