suffix:sep后跟的正规式表达(regular expression)python的正规式表达大家可以学一下,很有用 但这个表跑出来,索引部分是id 和季度,列是Employee、Q3、Q4,如果我们想把季度和字段加到列里,可以用reset_index(): df1=pd.wide_to_long(df,#datasetstubnames=['Q3','Q4'],i='id',j='年份',sep='-')df1=df...
To get my desired output I have the following code where I am usingpd.wide_to_long ilist = ['g1','g2','g3'] stublist = ['st1','st1_Next','st2','ft'] df_long = pd.wide_to_long( df.reset_index(), i=['index']+ilist , stubnames= stublist, j='j', sep='_').reset...
其实Pandaswide_to_long()使用了Pandas的melt函数。但是Pandas的wide_to_long()更易于使用。例如,原始的gapminder数据框以宽格式包含一段时间内的多个变量,lifeExp,gdpPercap和pop。我们可以使用Pandas的wide_to_long()存根名称来指定多个变量,然后将其重塑为长格式。例如,要随着时间的推移在gapminder数据框中以宽幅形...
Pandas wide格式转置为long格式 Pandas是一个基于Python的数据分析库,提供了丰富的数据结构和数据分析工具。在Pandas中,wide格式和long格式是指数据表的不同排列方式。 Wide格式是指数据表中每一列代表一个变量,每一行代表一个观察值。这种格式适合于数据集较小、宽度较大的情况,但在进行数据分析和可视化时可能不够灵...
是关于数据处理的一种常见操作,涉及到datetime索引的使用和pandas中长表格(long table)到宽表格(wide table)的转换。 datetime索引:datetime索引是指将日期时间作为数据表的索引。它的优势在于方便对时间序列数据进行处理和分析。在pandas中,可以使用DatetimeIndex将某一列作为datetime索引,或者使用to_datetime函数将日期时间...
