Python Pandas - 返回索引中的所有元素是否均為 True
要返回索引中的所有元素是否都為 True,請在 Pandas 中使用 index.all() 方法。
首先,匯入所需的庫 −
import pandas as pd
建立索引 −
index = pd.Index([15, 25, 35, 45, 55])
顯示索引 −
print("Pandas Index...\n",index)
如果索引中的所有元素都為 True 則返回 True −
print("\nCheck whether all elements are True...\n",index.all())
示例
以下是程式碼 −
import pandas as pd # Creating the index index = pd.Index([15, 25, 35, 45, 55]) # Display the index print("Pandas Index...\n",index) # Return a tuple of the shape of the underlying data print("\nA tuple of the shape of underlying data...\n",index.shape) # Return the number of elements in the Index print("\nNumber of elements in the index...\n",index.size) # Return True if all the elements in the index are True print("\nCheck whether all elements are True...\n",index.all())
輸出
這將生成以下程式碼 −
Pandas Index... Int64Index([15, 25, 35, 45, 55], dtype='int64') A tuple of the shape of underlying data... (5,) Number of elements in the index... 5 Check whether all elements are True... True
