使用(嵌套？)重命名具有不同类别的多个变量循环

# 假设有三个变量，分别属于字符串、整数和布尔类型
var1 = "Hello"
var2 = 123
var3 = True

# 使用嵌套循环重命名变量
for category in ["str", "int", "bool"]:
    if category == "str":
        for i in range(1, 4):
            globals()[f"{category}_{i}"] = globals()[f"var{i}"]
            del globals()[f"var{i}"]
    elif category == "int":
        for i in range(1, 4):
            globals()[f"{category}_{i}"] = globals()[f"var{i}"]
            del globals()[f"var{i}"]
    elif category == "bool":
        for i in range(1, 4):
            globals()[f"{category}_{i}"] = globals()[f"var{i}"]
            del globals()[f"var{i}"]

# 打印重命名后的变量
print(str_1)   # 输出：Hello
print(int_2)   # 输出：123
print(bool_3)  # 输出：True
