Regarding question on coding

Comprehensions can be unwound. Start at the end and work your way back to the assignment. Use the same process, but in reverse, to convert for loops to a comprehension.

for child in children:
    for month in months:
        dataset1.append(
            (month, np.dot(month, 24.7)+np.random.normal(loc=0, scale=20))
            )
