Python read/write CSV file

1. Import python built-in module CSV

Import CSV

2. Read the contents of the CSV file

Csv_file = Csv.reader (open ("csvfile.csv","R"))  for inch csv_file:     Print (line)

When using iterators to read CSV content, each row in the CSV is a list that loops through each list.

3. Write to CSV file

Csv_file = Csv.writer (open ("localpicture.csv","w", newline= "" ) )    for in  get_pic_list (path):        Csv_file.writerow ([line])

If you do not add newline will result in each line will be more than one line of space, not a list in lines, will be the line of each character in a column, as the list passed in as if only a row of content.
