pandas how to check dtype for all columns in a dataframe?

It seems that dtype only work for pandas.DataFrame.Series, right? Is there a function to display data types of all columns at once?

The singular form dtype is used to check the data type for a single column. And the plural form dtypes is for data frame which returns data types for all columns. Essentially:

For a single column :

    dataframe.column.dtype

For all columns :

    dataframe.dtypes

Example :

    import pandas as pd
    df = pd.DataFrame({'A': [1,2,3], 'B': [True, False, False], 'C': ['a', 'b', 'c']})

    df.A.dtype
    # dtype('int64')
    df.B.dtype
    # dtype('bool')
    df.C.dtype
    # dtype('O')

    df.dtypes
    #A     int64
    #B      bool
    #C    object
    #dtype: object
