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
