Python - 显示 Pandas 索引中非 NA 条目
要查看 Pandas 索引中哪些条目不是 NA,请使用 index.notna() 方法。首先,导入必需的库 -
import pandas as pd import numpy as np
使用一些 NaN 值创建 Pandas 索引 -
index = pd.Index([5, 65, np.nan, 17, 75, np.nan])
显示 Pandas 索引 -
print("Pandas Index...\n",index)显示 Pandas 索引中哪些条目不是 NA。对于非 NA 条目返回 True -
print("\nCheck which entries are not-NA...\n", index.notna())
范例
以下是代码 -
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 not-NA
# Return True for non-NA entries
print("\nCheck which entries are not-NA...\n", index.notna())输出
将生成以下输出 -
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 not-NA... [ True True False True True False]
