Python Coding Specialist Exam

What is the purpose of using 'import' in Python coding?

• To confuse other programmers

• To increase the code complexity

• To delete existing code

• To bring in external modules or libraries

Explain the difference between '==' and 'is' operators in Python.

• '==' compares references, 'is' compares values.

• '==' compares identities, 'is' compares values.

• '==' compares values, 'is' compares identities.

• '==' compares memory addresses, 'is' compares values.

How can you handle exceptions in Python code?

• Handle exceptions with if-else statements in Python code.

• Ignore exceptions in Python code.

• Use try-except blocks in Python code.

• Use try-catch blocks in Python code.

What is the significance of 'self' in Python classes?

• The 'self' parameter is used to define new instances of a class

• The 'self' parameter refers to the instance of the class itself and is used to access variables and methods within the class.

• The 'self' parameter is used to access global variables outside the class

• The 'self' parameter is optional and can be omitted in class methods

Describe the use of list comprehension in Python.

• List comprehension in Python is used to create dictionaries instead of lists.

• List comprehension in Python is a concise way to create lists by providing a more readable and efficient alternative to traditional loops.

• List comprehension cannot be nested within other list comprehensions.

• List comprehension is a slower and less efficient method compared to traditional loops.

What is the difference between 'append()' and 'extend()' methods in Python lists?

• The 'append()' method adds elements at the beginning of the list, while the 'extend()' method adds elements at the end.

• Both 'append()' and 'extend()' methods add a single element to the list.

• The 'append()' method adds elements to the middle of the list, while the 'extend()' method adds elements to the beginning.

• The 'append()' method adds a single element to the end of the list, while the 'extend()' method adds multiple elements (iterable) to the end of the list.

How can you create a virtual environment in Python?

• python -m venv create myenv

• python create-env myenv

• python3 -m venv myenv

• python3 -m env myenv

Explain the concept of inheritance in Python.

• Inheritance in Python is achieved by creating a new class that has no relation to existing classes.

• Inheritance in Python involves copying all attributes and methods from the base class to the derived class.

• Inheritance in Python can only occur between classes within the same module.

• In Python, inheritance is achieved by creating a new class that derives from an existing class. The derived class (child class) inherits the attributes and methods of the base class (parent class).

What is the role of 'lambda' functions in Python?

• Lambda functions in Python are used for handling exceptions

• Lambda functions in Python are used to create small, anonymous functions at runtime.

• Lambda functions in Python are used for creating classes

• Lambda functions in Python are used for defining global variables

How can you use 'pip' to install Python packages?

• pip install --package_name

• pip install -p package_name

• pip install package_name

• pip install package
