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]
