Python - 返回 Pandas 索引的最大值
要返回 Pandas 索引的最大值,請使用 index.max() 方法。首先,匯入所需的庫 -
import pandas as pd
建立 Pandas 索引
index = pd.Index([10, 20, 70, 40, 90, 50, 25, 30])
顯示 Pandas 索引 −
print("Pandas Index...\n",index)獲取最大值 −
print("\nMaximum value..\n", index.max())
示例
以下為程式碼 −
import pandas as pd
# Creating Pandas index
index = pd.Index([10, 20, 70, 40, 90, 50, 25, 30])
# Display the Pandas 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 the dtype of the data
print("\nThe dtype object...\n",index.dtype)
# get the maximum value
print("\nMaximum value..\n", index.max())輸出
將產生以下輸出 −
Pandas Index... Int64Index([10, 20, 70, 40, 90, 50, 25, 30], dtype='int64') Number of elements in the index... 8 The dtype object... int64 Maximum value.. 90
