Python - 获取列的数据类型
要获取列的数据类型,请使用info()方法。让我们首先导入所需的库 -
import pandas as pd
创建一个具有 2 列具有不同数据类型的 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完整信息 -
dataFrame.info()
示例
以下是完整的代码 -
import pandas as pd输出结果# 创建数据帧
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"
# 获取数据类型信息
print(dataFrame.info())
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
