What is the purpose of a function in Python?
The purpose of a function in Python is to encapsulate code for reuse and organization.
To define variables in Python
To handle exceptions in Python
To create classes in Python
How do you define a function in Python?
def function_name(parameters):
function_name(parameters) =>
create function_name(parameters)
function_name: parameters()
What is the difference between a function and a method in Python?
A function can only return a value, while a method cannot.
Methods are defined outside of classes, while functions are defined inside classes.
A function is independent, while a method is associated with an object.
A method is a type of function that cannot take parameters.
How can you return multiple values from a function?
Use a list to return values.
Return a single value only.
Return values through global variables.
Use a tuple to return multiple values from a function.
What is a common debugging technique in Python?
Using a debugger tool
Using print statements for debugging
Writing unit tests
Ignoring error messages
How can you use print statements for debugging?
Insert print statements to display variable values and program flow at key points in the code.
Insert print statements only at the beginning of the code.
Remove all print statements to avoid clutter in the output.
Use print statements to write comments in the code.
What is the purpose of the assert statement in debugging?
To optimize code performance during execution.
To verify assumptions and catch errors during debugging.
To automatically fix errors in the code.
To enhance the user interface of the application.
What tools can be used for debugging in Python?
pdb, logging, IDEs (PyCharm, VS Code), ipdb, PySnooper
assertions
try-except blocks
print statements
What is the syntax for a for loop in Python?
for variable in sequence[]
for (variable : sequence)
for each variable in sequence:
for variable in sequence:
How do you iterate over a list using a for loop?
for item in my_list: print(item)
for item in range(len(my_list)): print(my_list[item])
for item in my_list: print(item, end='')
for item in my_list: item.print()
What is the difference between a for loop and a while loop?
A for loop iterates a known number of times, while a while loop continues until a condition is false.
A for loop runs indefinitely, while a while loop stops after a set number of iterations.
A for loop is used for conditional statements, while a while loop is used for iteration.
A for loop requires a condition, while a while loop does not need any conditions.
How can you use the range() function in a for loop?
You can use range() to generate random numbers in a for loop.
You can use range() to create a list of strings.
You can use range() in a for loop to iterate over a sequence of numbers.
range() is used to define the number of iterations in a while loop.
What is the syntax for a while loop in Python?
for condition: code to execute
repeat condition: code to execute
do while condition: code to execute
while condition: # code to execute
What is the purpose of the break statement in loops?
The break statement continues to the next loop iteration.
The break statement terminates the loop execution.
The break statement skips the current iteration of the loop.
The break statement pauses the loop execution.
How can you use the continue statement in a loop?
The continue statement is used to exit the loop completely.
You can use the continue statement in a loop to skip the current iteration and continue with the next one.
You can use the continue statement to restart the loop from the beginning.
The continue statement ends the loop immediately.
