Python Pandas - 计算输入标签的切片位置
若要计算输入标签的切片位置,请使用 index.slice_locs() 方法。首先,导入必需的库 -
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)获取切片位置。“start”是开始的标签。“end”是结束的标签
print("\nThe slice locations with start and stop...\n",index.slice_locs(start='q', end='v'))
示例
以下是代码 -
import pandas as pd
# Create Pandas index object
index = pd.Index(list('pqrstuvwxyz'))
# 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 slice locations
# The "start" is the label to begin with
# The "end" is the label to end with
print("\nThe slice locations with start and stop...\n",index.slice_locs(start='q', end='v'))输出
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 locations with start and stop... (1, 7)
