Question

Can someone help me solve this? I need to return a single list. Not 2 separate lists. I also need to modify a list of numbers.

Function 3: In this function you must both return a value and modify in-place the input
parameter (when needed). The only functions you are allowed to use are range(), len(),
append(), insert(), remove(), pop() and the del keyword.
• Examples:
return value argument value after return
◦ func3([4,-3,7,-5,1]) → [-3,-5] [4,7,1]
◦ func3([4,-3,7,-5,1], 4) → [-3,-5,1] [4,7]
◦ func3([4,-3,7,-5,1], 10) → [4,-3,7,-5,1] [ ]

Answer 1

def func3(numbers, t=0):
    lower = []
    higher = []
    for num in numbers:
        if num < t:
            lower.append(num)
        else:
            higher.append(num)
    return [lower, higher]


print(func3([4, -3, 7, -5, 1]))
print(func3([4, -3, 7, -5, 1], 4))
print(func3([4, -3, 7, -5, 1], 10))

def func3(numbers, t=0):
    lower = []
    higher = []
    for num in numbers:
        if num < t:
            lower.append(num)
        else:
            higher.append(num)
    lower.extend(higher)
    return lower


print(func3([4, -3, 7, -5, 1]))
print(func3([4, -3, 7, -5, 1], 4))
print(func3([4, -3, 7, -5, 1], 10))
