Export List of Pandas Dataframes in Python

I am trying to export a list of pandas dataframes to 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()

I get the following error:

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

Any ideas as to how this could be fixed or alternative methods to accomplish the same thing? I do not know how long the list will be so doing it manually

You have to use zip to iterate through pairs of items from two lists like that. Try the following fix:

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()
