Python 3.4语法错误及其修复方法

def calculate_sum(numbers):
    total = 0
    for num in numbers:
        total += num
    return total

# 示例调用
my_numbers = [1, 2, 3, 4, 5]
result = calculate_sum(my_numbers)
print("Sum:", result)

# 错误示例及修复
try:
    print(result + "extra")  # TypeError
except TypeError as e:
    print(f"Error: {e}. Fix: Convert result to string before concatenation.")
    print("Sum:", str(result) + "extra")

try:
    print(my_numbers[10])  # IndexError
except IndexError as e:
    print(f"Error: {e}. Fix: Check if index is within bounds before accessing.")
    if len(my_numbers) > 10:
        print(my_numbers[10])
    else:
        print("Index out of range")
