Python - 返回 Pandas 索引的最小值
要返回 Pandas 索引的最小值,请使用 index.min() 方法。首先,导入所需的库 -
import pandas as pd
创建 Pandas 索引 -
index = pd.Index([10.5, 20.4, 40.5, 25.6, 5.7, 6.8, 30.8, 50.2])
显示 Pandas 索引 -
print("Pandas Index...\n",index)
获取最小值 -
print("\nMinimum value..\n", index.min())
示例
以下为代码 -
import pandas as pd # Creating Pandas index index = pd.Index([10.5, 20.4, 40.5, 25.6, 5.7, 6.8, 30.8, 50.2]) # 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 minimum value print("\nMinimum value..\n", index.min())
输出
这将产生以下输出 -
Pandas Index... Float64Index([10.5, 20.4, 40.5, 25.6, 5.7, 6.8, 30.8, 50.2], dtype='float64') Number of elements in the index... 8 The dtype object... float64 Minimum value.. 5.7
