Python – splitting dataframe into multiple dataframes based on column values and naming them with those values [duplicate]

Subsetting by distinct values is called a groupby, if simply want to iterate through the groups with a for loop, the syntax is:

for region, df_region in df.groupby('Region'):
    print(df_region)
