将冻结集合的元素写入熊猫数据框

Question

I have a frozen set whose elements are like this:

{frozenset({'e', 'f'}), frozenset({'a', 'b'}), frozenset({'c', 'd'}),....}

I want to write the elements in the frozen set to a pandas dataframe like this:

  col1 col2
0    a    b
1    c    d
2    e    f
..   ..   ..

What is the most efficient way to do this?

Answer 1

You can convert your set to a list then create the dataframe. Let's call your set dat in the example below:

df = pd.DataFrame(list(dat), columns=['col1', 'col2'])

Yields a separate row in the DataFrame for each set in dat .
