Python – 获取列的数据类型
要获取列的数据类型,请使用 info() 方法。我们首先导入所需的库 −
import pandas as pd
创建一个具有具有不同数据类型的两个列的 DataFrame −
dataFrame = pd.DataFrame( { "Student": ['Jack', 'Robin', 'Ted', 'Marc', 'Scarlett', 'Kat', 'John'],"Roll Number": [ 5, 10, 3, 8, 2, 9, 6] } )
获取有关数据类型的信息 −
dataFrame.info()
示例
以下是完整的代码 −
import pandas as pd # Create DataFrame dataFrame = pd.DataFrame( { "Student": ['Jack', 'Robin', 'Ted', 'Marc', 'Scarlett', 'Kat', 'John'],"Roll Number": [ 5, 10, 3, 8, 2, 9, 6] } ) print"DataFrame ...\n",dataFrame print"\nInfo and the datatypes of the columns in the dataframe:\n" # get the datatypes info print(dataFrame.info())
输出
这将产生以下输出 −
DataFrame ... Roll Number Student 0 5 Jack 1 10 Robin 2 3 Ted 3 8 Marc 4 2 Scarlett 5 9 Kat 6 6 John Info and the datatypes of the columns in the dataframe: <class 'pandas.core.frame.DataFrame'> RangeIndex: 7 entries, 0 to 6 Data columns (total 2 columns): Roll Number 7 non-null int64 Student 7 non-null object dtypes: int64(1), object(1) memory usage: 184.0+ bytes None
