import csv 

这是一个Python中的模块，它允许轻松读取/写入CSV文件，所以让我们先导入它。

with open(name_csv+'.csv', 'w+') as csvfile: 
     spamwriter = csv.writer(csvfile, delimiter=',') 
     spamwriter.writerow(list_of_rows) 
#Used to write 1 row, each element in the array will be seperated by a comma 

编辑：

with open('somecsv.csv','w+') as csvfile: 
    spamwriter = csv.writer(csvfile, delimiter='|') # Changed the delimiter (Way of separating) 
    # This opens the CSV file and we set some additional parameters 
    for row in table.findAll('tr')[::2]: 
     list_of_cell = [] 
     for cell in row.findAll('td')[:5]: 
      text = cell.text.replace(" ", "").strip() 
      text = text.replace('''...\n\n\n'''," |") #This one is added so it replaces string before Lot with comma 
      text = text.replace(''':\n''',':') #This one is added so it doesn't interfere 
      text = text.replace('''\n''','|') #Adds a comma before block 
      list_of_cell.append(text) 
     print(list_of_cell) 
     spamwriter.writerow(list_of_cell)
