A namespace in Python is a container that holds a set of identifiers, such as variables and functions. It helps to keep the identifiers separate and unique, avoiding naming conflicts between identifiers used in different parts of a program. Each module in Python has its own namespace and the built-in names have their own namespace as well.
Namespaces in Python are containers that contain mappings from names to objects. It ensures that names for variables do not clash across various parts of a program. Python has three basic kinds of namespaces: built-in (such as print), global (those defined at the module level), and local (inside functions). Each namespace has its scope and lifetime.
Namespaces are very important in Python for the management of variable names and to avoid conflicts. Built-in namespaces contain predefined names, global namespaces are at the module level, and local namespaces exist inside functions or blocks. Their scope determines accessibility, and Python manages them dynamically to ensure efficient memory usage.
