Python Pandas - 计算输入标签的切片索引器

要计算输入标签的切片索引器，请使用该方法。首先，导入所需的库-index.slice_indexer()

import pandas as pd

创建Pandas索引对象-

index = pd.Index(list(pqrstuvwxyz))

显示熊猫指数-

print("Pandas Index...\n",index)

获取切片索引器。“开始”是开始的标签。“结束”是结束的标签-

print("\nThe slice indexer with start and stop...\n",index.slice_indexer(start=s, end=w))

示例

以下是代码-

import pandas as pd #创建Pandas索引对象 index = pd.Index(list(pqrstuvwxyz)) #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) #获取切片索引器 # The "start" is the label to begin with # The "end" is the label to end with print("\nThe slice indexer with start and stop...\n",index.slice_indexer(start=s, end=w))输出结果

这将产生以下输出-

Pandas Index... Index([p, q, r, s, t, u, v, w, x, y, z], dtype=object) Number of elements in the index... 11 The slice indexer with start and stop... slice(3, 8, None)
