疑问：写代码时的函数老是记不得，或者找到了也不知道怎么用？
目前的想法是参考官方文档pandas找，看了一篇这种链接https://blog.csdn.net/lusongno1/article/details/117620979?utm_term=pandas%E6%9F%A5%E7%9C%8B%E5%87%BD%E6%95%B0%E7%9A%84%E6%96%B9%E6%B3%95&utm_medium=distribute.pc_aggpage_search_result.none-task-blog-2_allsobaiduweb~default-1-117620979&spm=3001.4430

今日问题1:pd.read_fwf

pd.read_fwf(
        fname,
        header=None,
        widths=[4,2,2,10,10,10,10,10],
        names=['year','month','day','prcp','pet','flow','tmax','tmin'],        
    )

pd.read_fwf()
有个不错的网站介绍pandas还有代码演示https://www.cjavapy.com/article/234/
