17 Questions
What is a base case in recursive functions?
The condition that stops the recursive calls and prevents infinite looping
How does recursion end in the context of the 'factorial' function?
When 'n' is equal to 1
Why is it important for recursive functions to have a base case?
To avoid infinite recursion and potential stack overflow
What happens if a recursive function does not have a base case?
It keeps calling itself indefinitely, leading to a maximum recursion depth exceeded error
What can happen if recursion is not implemented carefully in functions?
It can cause complex debugging and memory consumption issues
What is a global variable?
A variable that is accessible from anywhere in the code
What happens if 'a' is greater than 0 in a function?
The function terminates immediately without executing the subsequent 'print' statement
What error does it raise when trying to access a local variable outside the function?
'NameError'
How can you modify the value of a global variable inside a function?
By using the 'global' keyword in the function
What kind of variable is declared outside of any function?
Global variable
In which scope can a local variable be accessed?
Local scope
What is the purpose of functions in Python?
To perform a specific task, encapsulate code, and promote reusability
Why are functions considered important in programming?
To make programs more modular, readable, and maintainable
What is the purpose of the 'abs()' function in Python?
It returns the absolute value of a number
Which built-in function is used to receive input from the user in the form of a string?
input()
What does the 'eval()' function do in Python?
Evaluates a string as a Python expression and returns the result
Why is it beneficial to use range() function in Python?
To generate a sequence of numbers for iteration purposes
Learn about recursive functions, which call themselves with smaller values until reaching a base case. Without a base case, recursive functions would run indefinitely.
