Questions and Answers

What are some of the key features of Python that make it suitable for artificial intelligence?

Key features include f-strings, first-class functions, and built-in data structures like lists, tuples, sets, and dictionaries.

Explain the significance of having functions as first-class objects in Python.

This allows functions to be assigned to variables, passed as arguments, and returned from other functions, enhancing code flexibility.

What is the purpose of using generators in Python?

Generators allow for lazy evaluation, yielding values one at a time, which can save memory and improve performance.

Why is it important to test code when developing AI applications?

<p>Testing ensures that the code behaves as expected, helping to identify bugs and validate the effectiveness of algorithms.</p> Signup and view all the answers

What role do libraries like Matplotlib play in Python for AI?

<p>Libraries like Matplotlib enable data visualization, making it easier to interpret and understand complex datasets used in AI.</p> Signup and view all the answers

Explain the difference between late binding and early binding in the context of the provided Python functions.

<p>Late binding occurs when a function uses the most recent value of a variable at the time it is called, while early binding uses the value of the variable at the time the function is defined.</p> Signup and view all the answers

What is the advantage of using embedded function definitions over lambda functions in Python?

<p>Embedded function definitions allow for the inclusion of a <strong>doc</strong> string, enabling better documentation of the function's purpose.</p> Signup and view all the answers

How does the yield command relate to generators in Python?

<p>The yield command allows a function to return a value and pause its execution, making it possible to create generators that compute values only when needed.</p> Signup and view all the answers

Predict the output of 'print([f(10) for f in fun_list3])' and explain your reasoning.

<p>The output will be [14, 14, 14, 14, 14].</p> Signup and view all the answers

Describe how fun_list2 achieves early binding while fun_list3 does not.

<p>fun_list2 captures the value of iv at the time each function is defined, while fun_list3 captures i at the end of the loop, resulting in all functions referring to the same final value.</p> Signup and view all the answers

Late Binding

A function's variables are resolved when the function is called, not when it is defined. The values of these variables are the current values within the scope of the call.

Early Binding

A function's variables are resolved when the function is defined. The values of those variables stay fixed to the time of creation.

Lambda Function

A small, anonymous function, often defined inline. It typically uses a concise syntax to define simple expressions.

Nested Function

A function defined within another function. These inner functions can access variables from the enclosing function's scope, for example in fun2, iv depends on the i.
