Python Pandas - 计算对应于给定标签的左切片边界
要计算对应于给定标签的左切片边界，请使用.将side参数设置为left。index.get_slice_bound()
首先，导入所需的库-
import pandas as pd
创建熊猫索引-
index = pd.Index([10, 20, 30, 40, 50, 60, 70])
显示熊猫指数-
print("Pandas Index...\n",index)获取左切片绑定。如果“side”参数设置为“left”，则返回给定标签的左切片边界
print("\nGet the left slice bound...\n",index.get_slice_bound(30, side='left', kind ='getitem'))示例
以下是代码-
import pandas as pd
#创建Pandas索引
index = pd.Index([10, 20, 30, 40, 50, 60, 70])
#显示Pandas索引
print("Pandas Index...\n",index)
#返回索引中的元素数
print("\nNumber of elements in the index...\n",index.size)
#获取左切片边界
# Returns the left slice bound of given label if "side" 参数设置为 "left"
print("\nGet the left slice bound...\n", index.get_slice_bound(30, side='left', kind ='getitem'))输出结果这将产生以下输出-
Pandas Index... Int64Index([10, 20, 30, 40, 50, 60, 70], dtype='int64') Number of elements in the index... 7 Get the left slice bound... 2
