Singleton class for managing global variables with predefined and dynamic attributes.
|
||
|
|
|
||
|
|
Usage Example:
|
||
|
|
>>> # 1. Access predefined variable (with default value)
|
||
|
|
>>> print(Globals().repo_name) # Output: OleehyO/TexTeller
|
||
|
|
|
||
|
|
>>> # 2. Modify predefined variable
|
||
|
|
>>> Globals().repo_name = "NewRepo/NewProject"
|
||
|
|
>>> print(Globals().repo_name) # Output: NewRepo/NewProject
|
||
|
|
|
||
|
|
>>> # 3. Dynamically add new variable
|
||
|
|
>>> Globals().new_var = "hello"
|
||
|
|
>>> print(Globals().new_var) # Output: hello
|
||
|
|
|
||
|
|
>>> # 4. View all variables
|
||
|
|
>>> print(Globals()) # Output: <Globals: {'repo_name': ..., 'new_var': ...}>
