将元组列表写入txt文件 [英] Write list of tuples to txt file

问题描述

考虑以下元组列表:

list=[((0.0, 0.0), (0.00249999994412065, -509.707885742188), (0.00499999988824129, -1017.52648925781), (0.0087500000372529, -1778.51281738281), (0.0143750002607703, -2918.21899414063), (0.0228125005960464, -4609.91650390625))]

我想以以下格式将信息写入txt文件:

I'd like to write the information to a txt file in this format:

0.0 0.0
0.00249999994412065 -509.707885742188
.... 

我一直在使用以下代码:

I've been using this code:

with open(fname, 'w') as graphd:
    for row in list:
        print >>graphd, ', '.join(map(str, row))
graphd.close()

其中: fname是文件的路径 list是元组列表

where: fname is the path to the file list is the list of tuples

这将导致:(接近，但仍然不是我想要的...)

This results in: (which is close but still not what I want...)

推荐答案

问题是您要遍历列表，但是列表中仅包含一项，即一个元组的元组.因此，您必须遍历该元组的元组，即lis[0]

Problem is that you're iterating over the list but the list contains only one item, that is a tuple of tuples. So you must iterate over that tuple of tuples i.e lis[0]

lis=[((0.0, 0.0), (0.00249999994412065, -509.707885742188), (0.00499999988824129, -1017.52648925781), (0.0087500000372529, -1778.51281738281), (0.0143750002607703, -2918.21899414063),
