How to reorder array in Python with / without Pandas? -


in order search correlations between products , categories , next visualizations (heatmaps) need reorder array using python with/without pandas or other libraries this:

book name, category 1, category 2, category 3, django 101 python web-dev beginner ror guide rails web-dev intermediate laravel php web-dev intermediate

into that:

book name, python, web-dev, beginner, rails, php, intermediate django 101 true true true false false, false ror guide false true false false false, true laravel false true false false true, true

is there way that? data stored .csv file , read pandas.read_csv ()

this can done using get_dummies function in pandas.

df = pd.dataframe({'book name': ['django 101', 'ror guide', 'laravel'], 'category 1': ['python', 'rails', 'php'], 'category 2': ['web-dev']*3, 'category 3': ['beginner', 'intermediate', 'intermediate']})  dummies = pd.concat([pd.get_dummies(df[c]) c in df.columns[1:]], axis=1) df_new = pd.concat([df['book name'], dummies], axis=1)  >>> df_new     book name  php  python  rails  web-dev  beginner  intermediate 0  django 101    0       1      0        1         1             0 1   ror guide    0       0      1        1         0             1 2     laravel    1       0      0        1         0             1

or can reset index of dataframe book's name:

df.set_index('book name', inplace=true) df_new = pd.concat([pd.get_dummies(df[c]) c in df], axis=1) >>> df_new             php  python  rails  web-dev  beginner  intermediate book name                                                       django 101    0       1      0        1         1             0 ror guide     0       0      1        1         0             1 laravel       1       0      0        1         0             1
