Python Pandas - 計算與給定標籤相對應的左切片邊界
要計算與給定標籤相對應的左切片邊界,請使用index.get_slice_bound()。將side引數設定為left。
首先,匯入所需的庫 -
import pandas as pd
建立 Pandas 索引 -
index = pd.Index([10, 20, 30, 40, 50, 60, 70])
顯示 Pandas 索引 -
print("Pandas Index...\n",index)獲取左切片邊界。如果“side”引數設定為“left”,則返回給定標籤的左切片邊界
print("\nGet the left slice bound...\n",index.get_slice_bound(30, side='left', kind ='getitem'))
示例
以下是程式碼 -
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'))輸出
這將生成以下輸出 -
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
