def fib(n):
    a, b = 0, 1
    for _ in range(n):
        a, b = b, a + b
    return a
<p>print(‘fib(10) =’, fib(10))

Cell 2 — List Comprehension#

nums = [1, 2, 3, 4, 5]
<p>squares = [x**2 for x in nums]
print(‘Squares:’, squares)
print(‘Sum:’, sum(squares))

Cell 3 — String Operations#

text = 'Pyodide runs Python in your browser!'
print('Original:', text)
print('Upper:', text.upper())
print('Length:', len(text))

Cell 4 — Math Operations#

import math
<p>radius = 7
area = math.pi * radius**2
circumference = 2 * math.pi * radius</p>
<p>print(‘Radius:’, radius)
print(‘Area:’, round(area, 2))
print(‘Circumference:’, round(circumference, 2))
