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)
