python dictionary to pandas dataframe with multiple columns

Question

I have the following python dictionary:

d= {\'data\'      : Counter({ \'important\' : 2,
                        \'very\'      : 3}),
    \'analytics\' : Co         


        

Answer 1

You can use stack:

df = pd.DataFrame(d).stack().reset_index()
df.columns = ['word','category','count']
print(df)
        word   category  count
0     boring  analytics    5.0
1  important       data    2.0
2      sleep  analytics    3.0
3       very       data    3.0

---

df = pd.DataFrame.from_dict(d, orient='index').stack().reset_index()
df.columns = ['category','word','count']
print(df)

    category       word  count
0  analytics     boring    5.0
1  analytics      sleep    3.0
2       data  important    2.0
3       data       very    3.0

Another solution with nested list comprehension:

df = pd.DataFrame([(key,key1,val1) for key,val in d.items() for key1,val1 in val.items()])
df.columns = ['category','word','count']
print(df)
    category       word  count
0  analytics     boring      5
1  analytics      sleep      3
2       data  important      2
3       data       very      3
