We’ve included it here due to is popularity in Python 2. Because of this, we wouldn’t recommend using it in favour of one of the methods below. Note: This is considered a “legacy interface” in Python 3, and it may be deprecated at some point in the future.

However, we believe that it can be useful to know how to open URLs and interact with them without using a 3rd party and it may also help you appreciate why the requests package is so popular. The official documentation actually recommends that you might want to check out the 3rd party library, requests, for a higher-level HTTP client interface. We will be covering each part individually except for urllib.error. The current version of urllib is made up of the following modules: These are now a part of the urllib package in Python 3. If you are coming from a Python 2 background you will note that in Python 2 you had urllib and urllib2. The urllib module in Python 3 is a collection of modules that you can use for working with URLs. In other words, you won’t find urllib2 in Python 3 instead of urllib. The urllib module is the replacement of urllib2 as long as migrating from Python 2 to Python 3.

Specifying mode is the best way to ensure filesystem objects are created with the correct permissions. If mode is not specified and the destination filesystem object does exist, the mode of the existing filesystem object will be used. If mode is not specified and the destination filesystem object does not exist, the default umask on the system will be used when setting the mode for the newly created filesystem object. Giving Ansible a number without following one of these rules will end up with a decimal number which will have unexpected results.Īs of Ansible 1.8, the mode may be specified as a symbolic mode (for example, u+rwx or u=rw,g=r,o=r). You must either add a leading zero so that Ansible’s YAML parser knows it is an octal number (like 0644 or 01777) or quote it (like '644' or '1777') so Ansible receives a string and can do its own conversion from string into number. The permissions the resulting filesystem object should have.įor those used to /usr/bin/chmod remember that modes are actually octal numbers.
