Python - 建立一個 Pandas 索引,同時刪除傳入位置


要建立刪除傳入位置的新 Pandas 索引,請使用 **index.delete()** 方法。

首先,匯入所需的庫 ——

import pandas as pd

建立索引 ——

index = pd.Index([15, 25, 35, 45, 55])

顯示索引 ——

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

刪除第 3 個位置的單個索引,即索引 2 ——

print("\nRemaining Index after deleting an index at location 3rd (index 2)...\n",index.delete(2))

示例

以下是程式碼 ——

import pandas as pd

# Creating the index
index = pd.Index([15, 25, 35, 45, 55])

# Display the index
print("Pandas Index...\n",index)

# Return the number of elements in the Index
print("\nNumber of elements in the index...\n",index.size)

# Return a tuple of the shape of the underlying data
print("\nA tuple of the shape of underlying data...\n",index.shape)

# get the bytes in the data
print("\nReturn the bytes...\n",index.nbytes)

# get the dimensions of the data
print("\nReturn the dimensions...\n",index.ndim)

# deleting a single index at 3rd position i.e. index 2
print("\nRemaining Index after deleting an index at location 3rd (index 2)...\n",index.delete(2))

輸出

這將生成以下程式碼 ——

Pandas Index...
Int64Index([15, 25, 35, 45, 55], dtype='int64')

Number of elements in the index...
5

A tuple of the shape of underlying data...
(5,)

Return the bytes...
40

Return the dimensions...
1

Remaining Index after deleting an index at location 3rd (index 2)...
Int64Index([15, 25, 45, 55], dtype='int64')
