Python Math: Create a range for floating numbers

Python Math: Exercise-72 with Solution

Write a Python program to create a range for floating numbers.

Sample Solution:-

Python Code:

def frange(x, y, jump=1.0):
    i = 0.0
    x = float(x)  # Prevent yielding integers.
    y = float(y)  # Comparison converts y to float every time otherwise.
    x0 = x
    epsilon = jump / 2.0
    yield x  # yield always first value
    while x + epsilon < y:
        i += 1.0
        x = x0 + i * jump
        yield x

print(list(frange(0.0, 1.0, 0.1)))

Sample Output:

[0.0, 0.1, 0.2, 0.30000000000000004, 0.4, 0.5, 0.6000000000000001, 0.7000000000000001, 0.8, 0.9, 1.0]

Lambdas for Sorting:

>>> students = [{'name': 'John', 'score': 98}, {'name': 'Mike', 'score': 94}, {'name': 'Jennifer', 'score': 99}]
>>> sorted(students, key=lambda x: x['score'])
[{'name': 'Mike', 'score': 94}, {'name': 'John', 'score': 98}, {'name': 'Jennifer', 'score': 99}]
