Question

我正在将列表卡片组写入文件中，但是我需要每个列表中的每个项目在写入时都不要在其周围加上''。

deck = [['ad','ah','ac','as'],['2d','2h','2c','2s'],['3d','3h','3c','3s'],['4d','4h','4c','4s'],['5d','5h','5c','5s'],['6d','6h','6c','6s'],['7d','7h','7c','7s'],['8d','8h','8c','8s'],['9d','9h','9c','9s'],['td','th','tc','ts'],['jd','jh','jc','js'],['qd','qh','qc','qs'],['kd','kh','kc','ks']]

f = open('list.txt','w')
for i in deck:
    a=str(i)[1:-1].strip("'")+"\n"
    f.writelines(a)
f.close()

在上面的代码中我看到了ive试图使用.strip（），但是这并没有起作用，因为它只删除了第一个和最后一个引号。有没有办法让文本文件看起来像这样：

ad, ah, ac, as
2d, 2h, 2c, 2s
3d, 3h, 3c, 3s
4d, 4h, 4c, 4s
etc...

Answer 1

只需使用.replace("'", "")而不是.strip("'")。 Strip仅从字符串的左侧和右侧除去字符，而不是从中间除去字符，这就是为什么您看到在每一行上将数组打印为ad', 'ah', 'ac', 'as的原因：

deck = [['ad','ah','ac','as'],['2d','2h','2c','2s'],['3d','3h','3c','3s'],['4d','4h','4c','4s'],['5d','5h','5c','5s'],['6d','6h','6c','6s'],['7d','7h','7c','7s'],['8d','8h','8c','8s'],['9d','9h','9c','9s'],['td','th','tc','ts'],['jd','jh','jc','js'],['qd','qh','qc','qs'],['kd','kh','kc','ks']]

f = open('list.txt','w')
for i in deck:
    a=str(i)[1:-1].replace("'", "")+"\n"
    f.writelines(a)
f.close()

Answer 2

您可以按照以下步骤进行操作：

for each in deck:
  for INDEX, EACH in enumerate(each):
    if INDEX==0:
      print(EACH,end='')
    else:
      print(','+EACH,end='')
  print('\n')

产生输出：

ad,ah,ac,as

2d,2h,2c,2s

3d,3h,3c,3s

4d,4h,4c,4s

...

Answer 3

使用join将每个子列表的不同部分与', '连接起来：

deck = [['ad','ah','ac','as'],['2d','2h','2c','2s'],['3d','3h','3c','3s'],['4d','4h','4c','4s'],['5d','5h','5c','5s'],['6d','6h','6c','6s'],['7d','7h','7c','7s'],['8d','8h','8c','8s'],['9d','9h','9c','9s'],['td','th','tc','ts'],['jd','jh','jc','js'],['qd','qh','qc','qs'],['kd','kh','kc','ks']]

with open('list.txt','w') as f:
    for sublist in deck:
        f.write(', '.join(sublist)+'\n')

输出（在list.txt中）：

ad, ah, ac, as
2d, 2h, 2c, 2s
3d, 3h, 3c, 3s
...

另外，请注意，最好使用with open...来确保无论发生什么情况文件都被关闭。

Answer 4

您要执行的操作是用csv fromat书写。即尝试这样的事情：

import csv


with open('list.txt','w') as f:
    writer = csv.writer(f, quoting=csv.QUOTE_NONE)
    writer.writerows(deck)

写入txt文件时删除所有引号
