I have a dict as follows:
data_dict = {'1.160.139.117': ['712907','742068'],
'1.161.135.205': ['667386','742068'],
'1.162.51.21': ['326136', '663056', '742068']}
I want to convert the dict into a dataframe:
df= pd.DataFrame.from_dict(data_dict, orient='index')
How can I create a dataframe that has columns representing the values of the dictionary and rows representing the keys of the dictionary?, as below:
pd.get_dummies(df.stack()).sum(level=0)
One way you could do it:
df.stack().reset_index(level=1)\
.set_index(0,append=True)['level_1']\
.unstack().notnull().mul(1)
Output:
326136 663056 667386 712907 742068
1.160.139.117 0 0 0 1 1
1.161.135.205 0 0 1 0 1
1.162.51.21 1 1 0 0 1
Or with a litte reshaping and pd.crosstab:
df2 = df.stack().reset_index(name='Values')
pd.crosstab(df2.level_0,df2.Values)
Output:
Values 326136 663056 667386 712907 742068
level_0
1.160.139.117 0 0 0 1 1
1.161.135.205 0 0 1 0 1
1.162.51.21 1 1 0 0 1
df.stack().reset_index(name="Values")\
.pivot(index='level_0',columns='Values')['level_1']\
.notnull().astype(int)
Output:
Values 326136 663056 667386 712907 742068
level_0
1.160.139.117 0 0 0 1 1
1.161.135.205 0 0 1 0 1
1.162.51.21 1 1 0 0 1
pd.get_dummies(df.stack()).sum(level=0)
Output:
326136 663056 667386 712907 742068
1.160.139.117 0 0 0 1 1
1.161.135.205 0 0 1 0 1
1.162.51.21 1 1 0 0 1
pd.get_dummies(df.stack()).sum(level=0) :-)
