Python - 在 Pandas 索引中顯示條目為 NA 的內容
若要顯示 Pandas 索引中哪些條目為 NA,請在 Pandas 中使用 index.isna()。首先,匯入所需的庫 -
import pandas as pd import numpy as np
建立帶有某些 NaN 值的 Pandas 索引 -
index = pd.Index([5, 65, np.nan, 17, 75, np.nan])
顯示 Pandas 索引 -
print("Pandas Index...\n",index)
顯示 Pandas 索引中哪些條目為 NA。對於 NA 條目返回 True -
print("\nCheck which entries are NA...\n", index.isna())
示例
以下是程式碼 -
import pandas as pd import numpy as np # Creating Pandas index with some NaN values index = pd.Index([5, 65, np.nan, 17, 75, np.nan]) # 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) # Show which entries in a Pandas index are NA # Return True for NA entries print("\nCheck which entries are NA...\n", index.isna())
輸出
將生成以下輸出 -
Pandas Index... Float64Index([5.0, 65.0, nan, 17.0, 75.0, nan], dtype='float64') Number of elements in the index... 6 The dtype object... float64 Check which entries are NA... [False False True False False True]
