Rolling window and apply code

[JunkBoy]

Hey
I have many large data frames that I need to split into several new data frames.
they need to be split in rolling window split. In this case the window is 12. But it can change.

FOr instance I Now have 250 row that I split into data frames like this... as you can see this is a very long end repetitive way to do this.. I believe there must be a smarter way to do this.

1 2 3 4 5

#df1 = df_all_sales.iloc[0:12].. df2 = df_all_sales.iloc[1:13].. and on and on   df1 = pd.DataFrame(df_all_sales, columns=['time', 'sales-transaction']).iloc[0:12]   df2 = pd.DataFrame(df_all_sales, columns=['time', 'sales-transaction']).iloc[1:13]   df3 = pd.DataFrame(df_all_sales, columns=['time', 'sales-transaction'])iloc[2:14]   df4 = pd.DataFrame(df_all_sales, columns=['time', 'sales-transaction']).iloc[3:15]

I need help to simplify and reduce the code to something so I can easily access the new Dfs.
Maybe make a for loop or something that can simplify this.
Thanks for advice!

I suggest to read Why you don't want to dynamically create variables and then (re)consider your options.

The thing is that I am moving my code from excel to python. I am very new to python and do not have the knowledge to really know what to consider as options in this case. I need advice or someone to set me on the right track.. :)

Why do you think you need a bunch of data frames? What ae you going to do with these data frames? Please describe what you are trying to accomplish instead of how.

I hope this helps you, help me.
Thanks!
