Python Pandas - 返回底層資料維度數
要返回底層資料維度數,請使用 index.ndim 屬性。
首先,匯入所需庫 -
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)獲取資料維度 -
print("\nReturn the dimensions...\n",index.ndim)
示例
以下為程式碼 -
import pandas as pd
# Creating the index
index = pd.Index([15, 25, 35, 45, 55])
# Display the index
print("Pandas Index...\n",index)
# Return an array representing the data in the Index
print("\nArray...\n",index.values)
# 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)輸出
這將生成以下程式碼 -
Pandas Index... Int64Index([15, 25, 35, 45, 55], dtype='int64') Array... [15 25 35 45 55] A tuple of the shape of underlying data... (5,) Return the bytes... 40 Return the dimensions... 1
