Python:将数据框转换为列表，列表中包含字符串项 [英] Python: Convert dataframe into a list with string items inside list

问题描述

我目前有读取Excel表中的代码(下图):

I currently have code that reads in an Excel table (image below):

# Read in zipcode input file

us_zips = pd.read_excel("Zipcode.xls")
us_zips

我使用以下代码将数据框的邮政编码转换为列表:

I use the following code to convert the dataframe zip codes into a list:

us_zips = list(us_zips.values.flatten())

当我打印us_zips时，它看起来像这样:

When I print us_zips it looks like this:

[10601、60047、50301、10606]

[10601, 60047, 50301, 10606]

...但是我希望它看起来像这样["10601"，"60047"，"50301"，"10606"]

...but I want it to look like this ["10601", "60047", "50301", "10606"]

我该怎么做? *非常感谢您的帮助

How can I do that? *Any help is greatly appreciated

推荐答案

您可以使用

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:

In [321]:
us_zips['zipcode'].astype(str).values.tolist()

Out[321]:
['10601', '60047', '50301', '10606']
