Python - Nested List to Tab Delimited File?
提问by Darren J. Fitzpatrick
I have a nested list comprising ~30,000 sub-lists, each with three entries, e.g.,
我有一个包含 ~30,000 个子列表的嵌套列表，每个子列表都有三个条目，例如，
nested_list = [['x', 'y', 'z'], ['a', 'b', 'c']].
I wish to create a function in order to output this data construct into a tab delimited format, e.g.,
我希望创建一个函数，以便将此数据构造输出为制表符分隔的格式，例如，
x y z
a b c
Any help greatly appreciated!
非常感谢任何帮助！
Thanks in advance, Seafoid.
提前致谢，海鱼。

with open('fname', 'w') as file:
file.writelines('\t'.join(i) + '\n' for i in nested_list)

>>> nested_list = [['x', 'y', 'z'], ['a', 'b', 'c']]
>>> for line in nested_list:
... print '\t'.join(line)
...
x y z
a b c

In my view, it's a simple one-liner:
在我看来，这是一个简单的单行：
print '\n'.join(['\t'.join(l) for l in nested_list])

>>> print '\n'.join(map('\t'.join,nested_list))
x y z
a b c

回答by fortran
out = file("yourfile", "w")
for line in nested_list:
print >> out, "\t".join(line)
