6 min readTo create a multicolumn table with Matplotlib, you can use the table function from Matplotlib's matplotlib.pyplot module. This function allows you to create a table with multiple columns by specifying the column widths and the data to be displayed in each cell. You can also customize the appearance of the table by setting various properties such as cell colors, fonts, and borders.

4 min readTo map atomic values in an array in Rust, you can use the iter() method on the array to create an iterator over its elements. Then, you can use the map() method on the iterator to transform each element using a closure. This closure takes the current element as an argument and returns the transformed value.For example, suppose you have an array arr of integers and you want to double each element.

6 min readIn pytest, you can use override parameters of a fixture by using the request fixture and accessing the param attribute. This allows you to dynamically change the parameters of a fixture when it is called in a test function. By using this feature, you can customize the behavior of a fixture based on the specific test case that is being run. This can be useful for scenarios where you need to override certain default values or configurations of a fixture for a specific test case.

4 min readTo create a multi-column text annotation in matplotlib, you can use the plt.text() function and format the text using newline characters (\n) to separate the content into different columns. For example, you can pass a string with multiple lines of text to the plt.text() function and use \n to create column breaks. Additionally, you can adjust the x and y parameters to position the annotation where you want it to appear in your plot.

5 min readTo make a HashSet of enum values in Rust, you first need to define the enum type with the variants you want to store in the set. Then, you can use the std::collections::HashSet type to create a HashSet and add enum values to it using the insert method. For example: use std::collections::HashSet; #[derive(Debug, PartialEq, Eq, Hash)] enum Color { Red, Green, Blue, } fn main() { let mut colors = HashSet::new(); colors.insert(Color::Red); colors.
-
4 min readIn pytest, you can run only unmarked tests by using the "-m" option along with the "not" keyword. This allows you to select tests based on markers that have not been applied to them. For example, you can run only unmarked tests by using the command "pytest -m 'not marked_test'". This will execute all tests that do not have the "marked_test" marker assigned to them.
-
2 min readTo install matplotlib using pip, you can use the following command:pip install matplotlibThis command will download and install the matplotlib library on your system, allowing you to use it in your Python projects. Make sure you have pip installed on your system before running this command.Once the installation is complete, you can import matplotlib in your Python script and start using its plotting capabilities to create visualizations and graphs.
-
7 min readIn Rust, you can run async tasks in several threads by utilizing the tokio library. First, import the necessary dependencies in your Cargo.toml file. Next, create an async task using the async keyword and tokio::spawn function. This will create a separate thread to execute the task concurrently. You can also use tokio::task::spawn_blocking to run a blocking task in a separate thread.
-
3 min readTo draw a circle without fill in Matplotlib, you can use the "circle" method from the "patches" module.First, import the necessary modules: import matplotlib.pyplot as plt import matplotlib.patches as patches Then, create a figure and axis object: fig, ax = plt.subplots() Next, create a circle patch with the desired radius and center coordinates: circle = patches.Circle((0.5, 0.5), radius=0.3, fill=False) Add the circle patch to the axis object: ax.
-
6 min readIn pytest, you can pass arguments to your test functions by using the command line. To do this, you can use the -k option followed by the expression that matches the test functions you want to run. For example, to run test functions that contain the word "login" in their names, you can use the command pytest -k "login".You can also pass custom arguments to your test functions by using the -m option followed by a marker expression.
-
4 min readTo sort an immutable slice in Rust, you can use the sort method provided by the standard library. This method takes a comparison function as an argument, which determines the ordering of the elements in the slice.To use the sort method on an immutable slice, you can create a mutable copy of the slice using the to_vec method, sort the copy, and then convert it back to an immutable slice using the as_slice method.
