Python Pandas - 计算与给定标签相对应的左切片边界
要计算与给定标签相对应的左切片边界,请使用index.get_slice_bound()。将side参数设置为left。
首先,导入所需的库 -
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)
获取左切片边界。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 # Creating Pandas index index = pd.Index([10, 20, 30, 40, 50, 60, 70]) # Display the Pandas index print("Pandas Index...\n",index) # Return the number of elements in the Index print("\nNumber of elements in the index...\n",index.size) # Get the left slice bound # Returns the left slice bound of given label if "side" parameter is set to "left" print("\nGet the left slice bound...\n", index.get_slice_bound(30, side='left', kind ='getitem'))
输出
这将生成以下输出 -
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
