What is the consequence of using wildcard imports (e.g., from module import *)?

• A. It improves code readability
• B. It may cause conflicts with existing names in the namespace
• C. It is the recommended way to import:
• D. It restricts access to only certain classes

Answer: (B)

Using wildcard imports, such as `from module import *`, can lead to unexpected behavior because it imports all public names from the specified module into the current namespace. This practice can introduce a risk of name conflicts, particularly if the current namespace already contains variables, functions, or classes with the same names as those being imported. Consequently, if two different modules contain a function or class with the same name, it can cause confusion and make the code difficult to debug, as it may not be clear which version of the name is being used. The other options do not accurately represent the implications of using wildcard imports. For example, while some may think that this approach improves code readability by reducing the need to prefix identifiers with the module name, it actually complicates this aspect by making it harder to know the origin of each name. Wildcard imports are generally not recommended because they compromise the clarity of the code, making it less maintainable. Additionally, the use of wildcard imports does not restrict access to certain classes; rather, it opens up the entire public API of the module being imported, leading to the potential for increased name clashes.
