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
