列表到字符串的转换

Question

I have a list of lists like so:

list = [[10, 11, 12, 13][14, 15, 16, 17]]

I want to convert them to Strings but maintain the list organization

list = [["10", "11", "12", "13"]["14", "15", "16", "17"]]

How would I do that?

Answer 1

Try this, using nested list comprehensions and the str() built-in function to perform the actual conversion:

lst = [[10, 11, 12, 13], [14, 15, 16, 17]]
lst = [[str(x) for x in slst] for slst in lst]

Now lst will look as expected:

lst
=> [['10', '11', '12', '13'], ['14', '15', '16', '17']]

Also notice that it's a bad idea to name a variable list , that clashes with a built-in function name. That's why I renamed it to lst .

Answer 2

list=[[10,11,12,13],[14,15,16,17]]
list=[map(str, list)for list in list]
print list

RESULT: [['10', '11', '12', '13'], ['14', '15', '16', '17']]

Answer 3

First of all, I think that you forgot to place a comma between your two sublist.

Secondly, do not use list as a variable name because you are shadowing the list data structure.

Finally, you can solve it using the map function:

>>> lst = [[10, 11, 12, 13],[14, 15, 16, 17]]
>>> map(lambda x: map(str, x), lst)
[['10', '11', '12', '13'], ['14', '15', '16', '17']]
>>>
