Python: Convert dataframe into a list with string items inside list
提问by PineNuts0
I currently have code that reads in an Excel table (image below):
我目前有读取 Excel 表格的代码(下图):
# Read in zipcode input file
us_zips = pd.read_excel("Zipcode.xls")
us_zips
I use the following code to convert the dataframe zip codes into a list:
我使用以下代码将数据框邮政编码转换为列表:
us_zips = list(us_zips.values.flatten())
When I print us_zips it looks like this:
当我打印 us_zips 时,它看起来像这样:
[10601, 60047, 50301, 10606]
[10601、60047、50301、10606]
...but I want it to look like this ["10601", "60047", "50301", "10606"]
...但我希望它看起来像这样 ["10601", "60047", "50301", "10606"]
How can I do that? *Any help is greatly appreciated
我怎样才能做到这一点?*任何帮助是极大的赞赏

You can just cast the column dtype using astype(str)
and then convert to list using .values.tolist()
, this returns a numpy array using .values
which has a member function to convert this to a list:
您可以只使用 dtypeastype(str)
转换列,然后使用转换为列表.values.tolist()
,这将返回一个 numpy 数组 using .values
,它具有将其转换为列表的成员函数:
In [321]:
us_zips['zipcode'].astype(str).values.tolist()
Out[321]:
['10601', '60047', '50301', '10606']

It worked for me without .values()
:
它对我有用,没有.values()
:
list = df[col_name].astype(str).tolist()
