It basically means that the object implements the __getitem__() method. In other words, it describes objects that are “containers”, meaning they contain other objects. This includes strings, lists, tuples, and dictionaries.
Requests is not a built in module (does not come with the default python installation), so you will have to install it: OSX/Linux Use $ pip install requests (or pip3 install requests for python3) if you have pip installed. If pip is installed but not in your path you can use python -m pip install requests (or python3 -m pip install requests for python3) Alternatively … Read more
The assignment operator has lower precedence than &&, so your condition is equivalent to: But the left-hand side of this is an rvalue, namely the boolean resulting from the evaluation of the subexpression match == 0 && k, so you cannot assign to it. By contrast, comparison has higher precedence, so match == 0 && k == m is … Read more
First of all, remember to indent your code for readability. Concept 1. Concept 2. // compare Strings using compareTo method (which returns 0 if equal Rest of your code and concepts are correct 🙂
You’re trying to use a dict as a key to another dict or in a set. That does not work because the keys have to be hashable. As a general rule, only immutable objects (strings, integers, floats, frozensets, tuples of immutables) are hashable (though exceptions are possible). So this does not work: To use a dict as a key you … Read more
This is because require() does not exist in the browser/client-side JavaScript. Now you’re going to have to make some choices about your client-side JavaScript script management. You have three options: Use the <script> tag. Use a CommonJS implementation. It has synchronous dependencies like Node.js Use an asynchronous module definition (AMD) implementation. CommonJS client side-implementations include (most of them require a build step before you … Read more
export is used to set environment variable in operating system. This variable will be available to all child processes created by current Bash process ever after. PS1 is the primary prompt which is displayed before each command, thus it is the one most people customize. read more: https://wiki.archlinux.org/index.php/Bash/Prompt_customization#Prompts And the statement: \[\033[36m\]\u\[\033[m\]@\[\033[32m\]\h:\[\033[33;1m\]\w\[\033[m\]\$dictates how the prompt is going to look … Read more
Because of how numbers are stored. Signed numbers are stored using something called “two’s complement notation”. Remember all variables have a certain amount of bits. If the most significant one of them, the one on the left, is a 0, then the number is non-negative (i.e., positive or zero), and the rest of the bits … Read more
New approach (inspired by @Kamil-Kiełczewski solution)Takes degree, percentage, percentage and returns css hex color: Example: Original version: (still OK, just longer) Takes degree, percentage, percentage and returns css hex color: Example:
You might try reducing your base memory under settings to around 3175MB and reduce your cores to 1. That should work given that your BIOS is set for virtualization. Use the f12 key, security, virtualization to make sure that it is enabled. If it doesn’t say VT-x that is ok, it should say VT-d or … Read more
