Python - 检查包含某些 NaN 的 Pandas 索引是否为浮点类型
要检查包含某些 NaN 的 Pandas 索引是否为浮点类型,请使用 **index.is_floating()** 方法。首先,导入所需的库 −
import pandas as pd import numpy as np
创建包含某些 NaN 的 Pandas 索引 −
index = pd.Index([5.7, 6.8, 10.5, np.nan,17.8, 25.6, np.nan ,np.nan, 50.2])
显示 Pandas 索引 −
print("Pandas Index...\n",index)
检查包含某些 NaN 的索引值是否为浮点类型 −
print("\nIndex values with some NaNs is a floating type?\n",index.is_floating())
示例
以下为代码 −
import pandas as pd import numpy as np # Creating Pandas index with some NaNs index = pd.Index([5.7, 6.8, 10.5, np.nan,17.8, 25.6, np.nan ,np.nan, 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 with some NaNs are floating type print("\nIndex values with some NaNs is a floating type?\n",index.is_floating())
输出
这将生成以下输出 −
Pandas Index... Float64Index([5.7, 6.8, 10.5, nan, 17.8, 25.6, nan, nan, 50.2], dtype='float64') Number of elements in the index... 9 The dtype object... float64 Index values with some NaNs is a floating type? True
