打开python控制台:

import platform
platform.architecture()[0]

它应该显示'64bit'或'32bit'根据您的平台。

或者(对于OS X二进制文件):

import sys
sys.maxsize > 2**32 
# it should display True in case of 64bit and False in case of 32bit

平台架构不是可靠的方法。 相反,我们:

$ arch -i386 /usr/local/bin/python2.7

在我的Centos Linux系统上，我做了以下操作: 1)启动Python解释器(我使用2.6.6) 2)运行如下代码:

import platform
print(platform.architecture())

它给了我

(64bit, 'ELF')

对于32位，它将返回32，对于64位，它将返回64

import struct
print(struct.calcsize("P") * 8)

试试这个:

import platform
platform.architecture()
