Python - 检查 Pandas 索引是否为浮点类型
要检查 Pandas 索引是否为浮点类型,请在 Pandas 中使用 index.is_floating() 方法。首先,导入所需的代码库 -
import pandas as pd
创建 Pandas 索引 −
index = pd.Index([5.7, 6.8, 10.5, 20.4, 25.6, 30.8, 40.5, 50.2])
显示 Pandas 索引 −
print("Pandas Index...\n",index)
检查索引值是否仅包含浮点数 −
print("\nIndex values only consists of floats?\n",index.is_floating())
示例
以下是代码 −
import pandas as pd # Creating Pandas index index = pd.Index([5.7, 6.8, 10.5, 20.4, 25.6, 30.8, 40.5, 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) # check whether index values has only floats print("\nIndex values only consists of floats?\n",index.is_floating())
输出
这将产生以下输出 −
Pandas Index... Float64Index([5.7, 6.8, 10.5, 20.4, 25.6, 30.8, 40.5, 50.2], dtype='float64') Number of elements in the index... 8 The dtype object... float64 Index values only consists of floats? True
