解决方法1:

def add_nums(a, b):
    return a + b

result = add_nums(2, 3)
print(result)

解决方法2:

nums = [1, 2, 3, 4, 5]
squared_nums = [num*num for num in nums]
print(squared_nums)

解决方法3:

def is_even(num):
    if num % 2 == 0:
        return True
    else:
        return False

print(is_even(4))

解决方法4:

sentence = "Hello, world!"
words = sentence.split()
print(words)

解决方法5:

def calculate_average(nums):
    total = sum(nums)
    average = total / len(nums)
    return average

nums = [1, 2, 3, 4, 5]
average = calculate_average(nums)
print(average)
