另一种迭代和添加换行符的方法:

for item in items:
    filewriter.write(f"{item}" + "\n")

简单:

with open("text.txt", 'w') as file:
    file.write('\n'.join(yourList))

with open ("test.txt","w")as fp:
   for line in list12:
       fp.write(line+"\n")

在Python 3中，你可以使用print和*进行参数解包:

with open("fout.txt", "w") as fout:
    print(*my_list, sep="\n", file=fout)

序列化列表到文本文件与逗号分隔值

mylist = dir()
with open('filename.txt','w') as f:
    f.write( ','.join( mylist ) )

这个逻辑首先将list中的项转换为字符串(str)。有时列表包含一个元组，如

alist = [(i12,tiger), 
(113,lion)]

这个逻辑将把每个元组写入一个新行。我们可以在读取文件时加载每个元组时使用eval:

outfile = open('outfile.txt', 'w') # open a file in write mode
for item in list_to_persistence:    # iterate over the list items
   outfile.write(str(item) + '\n') # write to the file
outfile.close()   # close the file
