Python Pandas - 返回 Index 中最小值的整形位置

要返回 Index 中最小值的整形位置，請使用 **index.argmin()** 方法。

首先，匯入所需要的庫 −

import pandas as pd

建立索引 −

index = pd.Index([15, 25, 55, 10, 100, 70, 35, 40, 55])

顯示索引 −

print("Pandas Index...\n",index)

獲取 Index 中最小值的整形位置 −

print("\nGet the int position of the smallest value in the Index...\n",index.argmin())

範例

以下是程式碼 −

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 smallest value in the Index
print("\nGet the int position of the smallest value in the Index...\n",index.argmin())

輸出

這將產生以下程式碼 −

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 smallest value in the Index...
3
