python - 在 Python 中导出 Pandas 数据框列表

Question

我正在尝试将 pandas 数据框列表导出到 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替代方法来完成同样的事情有什么想法吗？我不知道列表有多长，所以手动进行

Answer 1

您必须使用 zip 来迭代两个列表中的项目对，就像这样。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()
