Pandas' DataFrame.items() method is used to iterate over all pairs of column name (string) and column values (Series) in the DataFrame.

Parameters

The method items() does not take any parameters.

Return Value

An iterator of column_name (string) and content (Series).

WARNING

Do not modify column_name and content within the loop, as the source DataFrame may or may not be modified.

Examples

Consider the following DataFrame:


        
        
            
                
                
                    df = pd.DataFrame({"A":["a","b"],"B":["c","d"]})
df
                
            
               A  B
0  a  c
1  b  d

To iterate over the columns of df:


        
        
            
                
                
                    for column_name, content in df.items():
   print("column_name:", column_name)
   print(content)   # a Series
                
            
            column_name: A
0    a
1    b
Name: A, dtype: object
column_name: B
0    c
1    d
Name: B, dtype: object
