Python 中 Pandas 个数据帧的导出列表

Question

我正在尝试将 pandas 数据帧列表导出到 excel

list_of_df_to_dump = [df1,df2,...,df100]
list_of_tab_names = ['df1','df2',...,'df100']

writer = ExcelWriter(excel_name + '.xlsx')
for i,j in list_of_df_to_dump,list_of_tab_names:
     i.to_excel(writer,j,index = False)
writer.save()

我收到以下错误：

TypeError: 'DataFrame' objects are mutable, thus they cannot be hashed

关于如何解决这个问题或使用替代方法来完成同样的事情有什么想法吗？我不知道这个列表要多长时间，所以手动做

Answer 1

您必须使用 zip 来循环访问两个列表中的项目对。尝试以下修复：

list_of_df_to_dump = [df1,df2,...,df100]
list_of_tab_names = ['df1','df2',...,'df100']

writer = ExcelWriter(excel_name + '.xlsx')
for df, tab_name in zip(list_of_df_to_dump, list_of_tab_names):
     df.to_excel(writer, tab_name, index=False)
writer.save()
