code - jlab examples jlite

we’re tweaking style_jb2.css to render these a little more nicely

cells¶

# this is a code cell
print('hello world')
modulus = 3 * 107 * 2**30 + 1
modulus

hello world

344671125505

and one with some plots; note that there no longer is a need to add a final ; as myst takes care of that for us; it does trigger some sort of warning though

import matplotlib.pyplot as plt
import numpy as np

plt.title('Sine wave')
x = np.linspace(0, 2 * np.pi, 100)
y = np.sin(x)
plt.plot(x, y)

The history saving thread hit an unexpected error (OperationalError('attempt to write a readonly database')).History will not be written to the database.

[<matplotlib.lines.Line2D at 0x7f261bf30d40>]

while we’re at it, let’s see a cell with no output

# this is a code cell
# and it does not yield any output

code blocks¶

we can have inline code in the text that go on, or

# code blocks in Python
print('hello world')

// code blocks in JavaScript
console.log('hello world')

# code blocks in bash
echo hello world

<!-- code blocks in HTML -->
<!DOCTYPE html>
<html>
  <head>
    <title>hello world</title>
  </head>
  <body>
    <h1>hello world</h1>
  </body>
</html>

/* code blocks in CSS */
body {
  background-color: lightblue;
}

and so on and so forth
