我想你在寻找这样的答案。

f = open('output.txt','w')
list = [3, 15.2123, 118.3432, 98.2276, 118.0043]
f.write('a= {:>3d}, b= {:>8.4f}, c= {:>8.4f}, d= {:>8.4f}, e= 
{:>8.4f}\n'.format(*list))
f.close()

将stdout重定向到一个文件也可以用于此目的:

from contextlib import redirect_stdout
with open('test.txt', 'w') as f:
  with redirect_stdout(f):
     for i in range(mylst.size):
        print(mylst[i])

你打算怎么处理这个文件?这个文件是否存在于人类，或其他具有明确互操作性要求的程序?

如果您只是试图将列表序列化到磁盘，以便稍后由同一python应用程序使用，则应该pickle该列表。

import pickle

with open('outfile', 'wb') as fp:
    pickle.dump(itemlist, fp)

再读一遍:

with open ('outfile', 'rb') as fp:
    itemlist = pickle.load(fp)

我想你在寻找这样的答案。

f = open('output.txt','w')
list = [3, 15.2123, 118.3432, 98.2276, 118.0043]
f.write('a= {:>3d}, b= {:>8.4f}, c= {:>8.4f}, d= {:>8.4f}, e= 
{:>8.4f}\n'.format(*list))
f.close()

在Python3中你可以使用这个循环

with open('your_file.txt', 'w') as f:
    for item in list:
        f.print("", item)

另一种迭代和添加换行符的方法:

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