Python Pandas - 返回索引中最大值的整型位置
若要返回索引中最大值的整型位置,请使用 index.argmax() 方法。
首先,导入所需的库 −
import pandas as pd
创建索引 −
index = pd.Index([15, 25, 55, 10, 100, 70, 35, 40, 55])
显示索引 −
print("Pandas Index...\n",index)
获取索引中最大值的整型位置 −
print("\nGet the int position of the largest value in the Index...\n",index.argmax())
示例
下列为代码 −
import pandas as pd # Creating the index index = pd.Index([15, 25, 55, 10, 100, 70, 35, 40, 55]) # Display the index print("Pandas Index...\n",index) # Return a tuple of the shape of the underlying data print("\nA tuple of the shape of underlying data...\n",index.shape) # Return the number of elements in the Index print("\nNumber of elements in the index...\n",index.size) # The int position of the largest value in the Index print("\nGet the int position of the largest value in the Index...\n",index.argmax())
输出
这将产生以下代码 −
Pandas Index... Int64Index([15, 25, 55, 10, 100, 70, 35, 40, 55], dtype='int64') A tuple of the shape of underlying data... (9,) Number of elements in the index... 9 Get the int position of the largest value in the Index... 4
