在字典列表中写入具有字典名称的 CSV 文件

Question

Maybe it is a simple question but I can't find a similar one elsewhere.

I have a list of dictionaries like

all_dictionaries=[dictio1, dictio2, dictio3]

And I would like to save those dictionaries to different CSV files with each file having the name of the dictionaries like: dictio1.csv , dictio2.csv , dictio3.csv

So far I have written this code, but looping over a list of dictionaries meaning looping over the items of the general all_dictionaries . The problem is in the filename variable where it doesn't recognize the dictionary as a string but rather as a dictionary. Any idea how to get the name of the dictionary and place it as a file name?

for dictio in all_dictionaries:
    filename="%s.csv" %dictio
    with open(filename, 'wb') as csv_file:
        writer=csv.writer(csv_file)
        for key, value in dictio.items():
            writer.writerow([key, value])

You can't have the "variable name" as filename here. Maybe you should have a name key that has a filename as value in all of your dictionaries and then you can do a loop like...

for dictio in all_dictionnaries:
    filename="%s.csv" %dictio['name']
    with open(filename, 'wb') as csv_file:
        writer=csv.writer(csv_file)
        for key, value in dictio.items():
            writer.writerow([key, value])

This may get tedious when you have lots of dicts to handle. But i think this should work if you have small number of dicts.
