整个Python列表未写入CSV文件

Question

I have a Python list as output from a program which contains multiple lists inside it. I'm trying to write it into a CSV file, but only the fist part is getting written. The list is:

"['DELETE', 'FROM', 'abc', 'WHERE', ['c', '=', 'book']]\n- from: [['abc']]\n  [0]:\n    ['abc']\n- table: [['abc']]\n  [0]:\n    ['abc']\n- where_expr: ['c', '=', 'book']"

I converted the list to dictionary as follows:

   dict1={'delete': delete_list}
   df = pd.DataFrame(dict1, index=[0])

My output is:

         delete
0         ['DELETE', 'FROM', 'abc', 'WHERE', ['c', '=', 'book']]

I read some similar question and tried this..The entire output is written in the dataframe but I'm getting a single character in every row.

df2=pd.DataFrame([i for i in delete_list],columns=['Query'])
df2

Output is:

      Query
   0    [
   1    '
   2    D
   3    E
   4    L
   5    E
   6    T

   .
   .

it goes on....

What I'm actually trying is to have a different column for every nested list. Like 1st column will have the first list then 2nd column will have the list from: [['abc']]\\n [0]:\\n ['abc'] 3rd will have table: [['abc']] and so on.. Also how do I get rid of \\n?? strip() is not working!

If the goal is to write to a CSV file, you don't need pandas , simply use the csv module (in the standard library):

import csv
with open('dump.csv', 'w', newline='') as csvfile:
    writer = csv.writer(csvfile, delimiter=';', lineterminator='\n')
    writer.writerow([delete_list])

or perhaps

import csv
with open('dump.csv', 'w', newline='') as csvfile:
    writer = csv.writer(csvfile, delimiter=';', lineterminator='\n')
    writer.writerow(delete_list.split("\n"))
