Python Pandas - 返回索引值的空间使用量
要返回索引值的空间使用量,请在 Pandas 中使用 index.memory_usage() 方法。
首先,导入所需的库 −
import pandas as pd
创建索引 −
index = pd.Index([15, 25, 35, 45, 55])
显示索引 −
print("Pandas Index...\n",index)获取值的空间使用量 −
print("\nThe memory usage...\n",index.memory_usage())
示例
以下为代码 −
import pandas as pd
# Creating the index
index = pd.Index([15, 25, 35, 45, 55])
# Display the 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 a tuple of the shape of the underlying data
print("\nA tuple of the shape of underlying data...\n",index.shape)
# get the bytes in the data
print("\nReturn the bytes...\n",index.nbytes)
# get the dimensions of the data
print("\nReturn the dimensions...\n",index.ndim)
# get the memory usage of the values
print("\nThe memory usage...\n",index.memory_usage())输出
该代码将产生以下输出 −
Pandas Index... Int64Index([15, 25, 35, 45, 55], dtype='int64') Number of elements in the index... 5 A tuple of the shape of underlying data... (5,) Return the bytes... 40 Return the dimensions... 1 The memory usage... 40
