Python - 将 Pandas 类型转换为 set
要将熊猫类型转换为 Set,请使用 set()。首先,我们创建一个 DataFrame -
dataFrame = pd.DataFrame( { "EmpName": ['John', 'Ted', 'Jacob', 'Scarlett', 'Ami', 'Ted', 'Scarlett'], "Zone": ['North', 'South', 'South', 'East', 'West', 'East', 'North'] } )
将 pandas 类型转换为 set,然后执行 set union -
set(dataFrame.EmpName) | set(dataFrame.Zone)
示例
以下是完整的代码 -
import pandas as pd # Create DataFrame dataFrame = pd.DataFrame( { "EmpName": ['John', 'Ted', 'Jacob', 'Scarlett', 'Ami', 'Ted', 'Scarlett'], "Zone": ['North', 'South', 'South', 'East', 'West', 'East', 'North'] } ) print"DataFrame ...\n",dataFrame # Pandas into Set print"\nTypecast Pandas into Set...\n",set(dataFrame.EmpName) | set(dataFrame.Zone)
输出
将生成以下输出 -
DataFrame ... EmpName Zone 0 John North 1 Ted South 2 Jacob South 3 Scarlett East 4 Ami West 5 Ted East 6 Scarlett North Typecast Pandas into Set... set(['Ami', 'East', 'North', 'West', 'Ted', 'South', 'Jacob', 'John', 'Scarlett'])
