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')
