pvt.new(variable:str, value:Any=None) -> None

Functionality

Creates/updates variable files in ./data/ directory

Usage Example

pvt.new("user_profile", {"name": "John", "age": 28})  # Serializes to string 
pvt.new("system_flag")   # Creates empty file 

---

pvt.read(variable:str) -> str

Critical Notes

• Always wrap in try-except:

try:
    config = pvt.read("app_config")
except FileNotFoundError:
    initialize_defaults()

---

pvt.delete(variable:str) -> None

Security Notice

• Deletion is permanent. Recommended safety check:

if os.path.exists(pvt.data_dir + "/" + variable + ".var"):
    pvt.delete("temp_data") 

---

pvt.find (variable name: str) -> Bool

Use examples

Bool = pvt.find(str)
print(Bool) # True / False

pvt.new(变量名:str, 值:Any=None) -> None

功能 在./data/目录中创建/更新变量文件

使用示例

pvt.new("user_profile", {"name": "张三", "age": 28})  # 序列化为字符串 
pvt.new("system_flag")   # 创建空文件

---

pvt.read(变量名:str) -> str

重要说明

• 必须使用try-except包裹:

try:
    config = pvt.read("app_config")
except FileNotFoundError:
    initialize_defaults()

---

pvt.delete(变量名:str) -> None

安全提示

• 删除操作不可逆。建议进行安全检查:

if os.path.exists(pvt.data_dir + "/" + variable + ".var"):
    pvt.delete("temp_data")

---

pvt.find(变量名:str) -> Bool

使用示例

Bool = pvt.find(str)
print(Bool) # True / False
