Python - 将 Pandas 类型转换为 Set
pythonserver side programmingprogramming更新于 2025/10/28 9:48:17
要将 Pandas 类型转换为 Set，请使用 set()。首先，让我们创建一个 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，然后取 set union −
set(dataFrame.EmpName) | set(dataFrame.Zone)
示例
以下是完整代码 −
import pandas as pd
# 创建 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
这将产生以下输出 −
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'])
