Multiple Cells in One Loop Jupyter Notebook

Question

I have multiple codes written in different cells in jupyter notebook. The first cell contains the file name on which I need to perform the task. I am facing difficulty in running loop in jupyter notebook as I want to perform operation file by file. i.e. first take file1 to go through all the cells and then come back to lookout for file2 and so on.

I know a similar question has been asked Link1 but I am not sure how it can be done in jupter as I know in spyder we can indent in for loop and it'll run till we complete all the task then it jumps to another one but here in jupyter it seems difficult as it's cell by cell operation.

Cell 1 file_names = ['file1','file2','file3']
Cell 2 a = []
Cell 3 for file in file_names:
           a.append(file)

Answer 1

Your distribution of code to the cells is fine (i.e. it is one possibility out of many).

You define variables in cells 1 and 2 and execute the loop in cell 3. Your file processing takes place only in cell 3.

Of course, every cell must contain valid python syntax (as must a script opened in spyder). This means the body of the for-loop must be correctly indented.
