Python For Loops

Which statement correctly identifies a core difference between for loops and while loops in Python?

What is the final value of result after executing the following Python code?

result = 0
for i in range(1, 10, 2):
    if i % 3 == 0:
        continue
    result += i
else:
    result += 10

Consider the code:

fact = 1
for i in range(1, 6):
    fact *= i
print(fact)

What mathematical concept does this code calculate?

What will be printed to the console when the following Python code is executed, and why?

for i in range(5):
    if i == 3:
        break
    print(i)
else:
    print("Loop completed!")

What output will the following nested loop produce?

for i in range(1, 4):
    for j in range(1, i + 1):
        print(j, end='')
    print()

Consider the following code snippet:

my_list = ['apple', 'banana', 'cherry']
for index, item in enumerate(my_list):
    if index == 1:
        my_list.remove('banana')
    print(item)

What will be printed when this code is executed, and explain why?

How does the pass statement function within a for loop in Python and why is it utilized?

Given the following Python code using a for loop with range():

for i in range(2, 20, 3):
    print(i, end=' ')

What will be the output of this code?

In Python, can a for loop iterate directly over a dictionary? If so, what is the default behavior?

Explain the purpose and behavior of the else block in conjunction with a Python for loop. Under what condition(s) will the else block NOT execute?

What is the most accurate description of a 'nested loop'?

How can you modify the increment value in a for loop using the range() function?

Under what circumstances would you choose a while loop over a for loop in Python?

Which data types can a Python for loop be used to iterate over?

What happens if you try to modify a list while iterating over it with a for loop in Python?

What is the output of the following code that uses the range() function with a negative step?

for i in range(5, -1, -1):
    print(i, end=' ')

What is the result of attempting to use the break statement within a nested loop?

When iterating through a dictionary using a for loop, how can you access both the keys and their corresponding values?

What is the primary purpose of using nested loops in programming?

What will the value of sum_val be after the following code executes?

sum_val = 0
for i in range(1, 6):
    if i % 2 == 0:
        continue
    sum_val += i

Consider the scenario where you need to iterate through two lists simultaneously and perform an operation on elements at the same index. What is the most Pythonic and efficient way to achieve this?

How does python handle the situation where you try to loop with for statement on empty list?

What is the purpose of the continue statement in a Python loop?

What is the time complexity for iterating through a list with nested loop and dictionary lookup, and which one impacts the final result, with a big O notation?

What code snippet will you use to check if an element isn't available in list or string without looping it.

Is it necessary to assign a new variable i++ or other increment to increase a for loop's range?

If a for loop using range() is provided from parameters of 1 to n without an increment, what would be its default increment value, with n as a positive integer?
