如何在Python中生成混合类型列表

mixed_list = [1, 2.0, "hello", True]
print(mixed_list)

mixed_list = [i if i % 2 == 0 else float(i) for i in range(5)]
print(mixed_list)

mixed_list = []
mixed_list.append(1)
mixed_list.append(2.0)
mixed_list.append("hello")
mixed_list.append(True)
print(mixed_list)

mixed_list = [1, 2.0, "hello", True]
result = mixed_list[2] + 1  # 这里会报错，因为"hello"是字符串，不能和整数相加

if isinstance(mixed_list[2], str):
    print("This is a string")
else:
    result = mixed_list[2] + 1

for item in mixed_list:
    if isinstance(item, int):
        print(f"Integer: {item}")
    elif isinstance(item, float):
        print(f"Float: {item}")
    elif isinstance(item, str):
        print(f"String: {item}")
    elif isinstance(item, bool):
        print(f"Boolean: {item}")
