循环创建多个数据框 [英] Create multiple dataframes in loop

问题描述

我有一个列表，每个条目都是公司名称

I have a list, with each entry being a company name

companies = ['AA', 'AAPL', 'BA', ....., 'YHOO']

我想为列表中的每个条目创建一个新的数据框.

I want to create a new dataframe for each entry in the list.

类似

(伪代码)

for c in companies:
     c = pd.DataFrame()

我正在寻找一种方法来执行此操作，但找不到它.有任何想法吗?

I have searched for a way to do this but can't find it. Any ideas?

推荐答案

您可以执行此操作(尽管显然如果要使用面向公众的代码，请非常谨慎地使用exec)

You can do this (although obviously use exec with extreme caution if this is going to be public-facing code)

for c in companies:
     exec('{} = pd.DataFrame()'.format(c))
