Python Pandas - 获取请求标签的整数位置，如果没有完全匹配，则查找最近的索引值
要获取请求标签的整数位置并在没有完全匹配的情况下查找最近的索引值，请使用.将方法参数值设置为最接近的。index.get_loc()
首先，导入所需的库-
import pandas as pd
创建熊猫索引-
index = pd.Index([10, 20, 30, 40, 50, 60, 70])
显示熊猫指数-
print("Pandas Index...\n",index)如果没有完全匹配，则获取最近索引值的位置。该值使用get_loc().
print("\nGet the location of the nearest index if no exact match...\n", index.get_loc(58, method="nearest"))示例
以下是代码-
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)
#返回索引中的元素数
print("\nNumber of elements in the index...\n",index.size)
#从给定索引获取整数位置
print("\nDisplay integer location from given index...\n",index.get_loc(20))
print("\nDisplay integer location from given index...\n",index.get_loc(50))
#如果没有完全匹配，则获取最近索引值的位置
# The value is set "nearest" 使用 "method" parameter of the get_loc()
print("\nGet the location of the nearest index if no exact match...\n", index.get_loc(58, method="nearest"))输出结果这将产生以下输出-
Pandas Index... Int64Index([10, 20, 30, 40, 50, 60, 70], dtype='int64') Number of elements in the index... 7 Display integer location from given index... 1 Display integer location from given index... 4 Get the location of the nearest index if no exact match... 5
