Python for Mac is a dynamic object-oriented programming language that can be used for many kinds of software development. It offers strong support for integration with other languages and tools, comes with extensive standard libraries, and can be learned in a few days. Python is an especially popular language among Mac sysadmins; this restriction is partly so that those learning Python for Mac-specific tasks have a mostly-complete list of known code and approaches from which to learn. Autocad lt 2016 system requirements. It's also to help those more experienced with Python to discover projects that.

I need a cross platform method of determining the MAC address of a computer at run time. For windows the 'wmi' module can be used and the only method under Linux I could find was to run ifconfig and run a regex across its output. I don't like using a package that only works on one OS, and parsing the output of another program doesn't seem very elegant not to mention error prone. Does anyone know a cross platform method (windows and linux) method to get the MAC address? If not, does anyone know any more elegant methods then those I listed above? One other thing that you should note is that uuid.getnode() can fake the MAC addr by returning a random 48-bit number which may not be what you are expecting.

Also, there's no explicit indication that the MAC address has been faked, but you could detect it by calling getnode() twice and seeing if the result varies. If the same value is returned by both calls, you have the MAC address, otherwise you are getting a faked address.

>>> print uuid.getnode.__doc__ Get the hardware address as a 48-bit positive integer. The first time this runs, it may launch a separate program, which could be quite slow. If all attempts to obtain the hardware address fail, we choose a random 48-bit number with its eighth bit set to 1 as recommended in RFC 4122. Using my answer from here: It would be important to know to which iface you want the MAC for since many can exist (bluetooth, several nics, etc.). This does the job when you know the IP of the iface you need the MAC for, using netifaces (available in PyPI): import netifaces as nif def mac_for_ip(ip): 'Returns a list of MACs for interfaces that have given IP, returns None if not found' for i in nif.interfaces(): addrs = nif.ifaddresses(i) try: if_mac = addrs[nif.AF_LINK][0]['addr'] if_ip = addrs[nif.AF_INET][0]['addr'] except IndexError, KeyError: #ignore ifaces that dont have MAC or IP if_mac = if_ip = None if if_ip == ip: return if_mac return None Testing: >>> mac_for_ip('169.254.90.191') '2c:41:38:0a:94:8b'. For Linux let me introduce a shell script that will show the mac address and allows to change it (MAC sniffing). Ifconfig eth0 grep HWaddr cut -dH -f2 cut -d -f2 00:26:6c:df:c3:95 Cut arguements may dffer (I am not an expert) try: ifconfig etho grep HWaddr eth0 Link encap:Ethernet HWaddr 00:26:6c:df:c3:95 To change MAC we may do: ifconfig eth0 down ifconfig eth0 hw ether 00:80:48:BA:d1:30 ifconfig eth0 up will change mac address to 00:80:48:BA:d1:30 (temporarily, will restore to actual one upon reboot).

The cross-platform package will work for this, if you don't mind taking on a dependency. It works with Python 2.6+ and 3.2+. It will try many different methods until either getting a address or returning None. From getmac import get_mac_address eth_mac = get_mac_address(interface='eth0') win_mac = get_mac_address(interface='Ethernet 3') ip_mac = get_mac_address(ip='192.168.0.1') ip6_mac = get_mac_address(ip6='::1') host_mac = get_mac_address(hostname='localhost') updated_mac = get_mac_address(ip='10.0.0.1', network_request=True) Disclaimer: I am the author of the package. For Linux you can retrieve the MAC address using a SIOCGIFHWADDR ioctl. Struct ifreq ifr; uint8_t macaddr[6]; if ((s = socket(AF_INET, SOCK_DGRAM, IPPROTO_IP)).

Advertisement Python is one of the most popular programming languages of recent years. Its clear syntax and readability make it the perfect coding language for beginners. It’s forgivable to think that learning Python was essential given its wide usage. This raises the question: when is Python NOT the right answer? When is the Python programming language the wrong language to learn and/or use? What Python Is Good For In short, Python is becoming the language of machine learning. Most machine language courses are written using the Python language, and coding education as a whole has adopted Python as the language to learn, with wide use in classrooms, on Raspberry Pi, and elsewhere.

These reasons, along with the plethora of big companies using Python, leave many thinking it is the main programming language of the future. But if Python is such a Swiss Army Knife, when wouldn’t you use it? You Want to Be a Web Developer Python is more than capable of large-scale web development.

Instagram is the largest site running Django, a Python web framework. This is no mean feat, as explains: “We began using Python early on because of its simplicity, but we’ve had to do many hacks over the years to keep it simple as we’ve scaled.” That said, Django is a robust, elegant framework.
