The index of the list matches the suffix of the dataframe. But i is being passed as a string and thus throwing an error. The reason I need to build it this way and not hard code the dataframes is because I will not know how many df_x will be created ...
Here is what I have for 2 Data Frames, it works perfect but I want to scale it to loop through a list of data frames so that I can make it a bit more dynamic. writer = pandas.ExcelWriter("MyData.xlsx", engine='xlsxwriter') Data.to_excel(writer, sheet_name=...
Pandas is a special tool that allows us to perform complex manipulations of data effectively and efficiently. Inside pandas, we mostly deal with a dataset in the form of DataFrame. DataFrames are 2-dimensional data structures in pandas. DataFrames consist of rows, columns, and data.A...
