# Let's create dummy variables for our categorical variables
cat_variables = ['cat_var_1', 'cat_var_2']
# Loop through each variable and create dummies for it
for var in cat_variables:
    cat_list = pd.get_dummies(df[var], prefix=var)
    df1 = df.join(cat_list)
    df = df1

# Grab all columns, including new dummy variables
variables = df.columns.values.tolist()
# Remove categorical variables since we now have dummy variables for them
variables_to_keep = [i for i in variables if i not in cat_variables]
# Keep only numeric and dummy categorical variables in our output
final_df = df[variables_to_keep]
