Retry for reattempting in Ruby - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to retry the block 3 times.

Ruby

retry_count = 0
begin
  puts 'Trying...'
  raise 'Error' if retry_count < 2
rescue
  retry_count += 1
  [1]
end

Drag options to blanks, or click blank then click option'

Anext

Bretry

Cbreak

Dredo

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'next' instead of 'retry' causes a syntax error.

Using 'break' exits the block instead of retrying.

The retry keyword restarts the begin block from the beginning.

2fill in blank

medium

Complete the code to retry only if the error message is 'Temporary failure'.

Ruby

begin
  puts 'Attempting...'
  raise 'Temporary failure'
rescue => e
  if e.message == [1]
    retry
  end
end

Drag options to blanks, or click blank then click option'

A"Temporary failure"

B"Permanent failure"

C'Temporary failure'

D'Permanent failure'

Attempts:

3 left

💡 Hint

Common Mistakes

Using single quotes instead of double quotes causes mismatch.

Comparing with wrong error message string.

The error message is a string, so it must be compared with double quotes "Temporary failure".

3fill in blank

hard

Fix the error in the retry logic to avoid infinite loop.

Ruby

attempts = 0
begin
  attempts += 1
  puts "Try #{attempts}"
  raise 'Fail' if attempts < 3
rescue
  if attempts < 3
    [1]
  else
    puts 'Giving up'
  end
end

Drag options to blanks, or click blank then click option'

Aredo

Bnext

Cbreak

Dretry

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'redo' causes infinite loop without incrementing attempts.

Using 'next' or 'break' causes syntax errors here.

retry restarts the begin block, allowing attempts to increase and eventually stop retrying.

4fill in blank

hard

Fill both blanks to retry only up to 5 times and print a message each retry.

Ruby

max_retries = 5
tries = 0
begin
  tries += 1
  puts "Attempt #{tries}"
  raise 'Error' if tries < max_retries
rescue
  if tries < [1]
    puts 'Retrying...'
    [2]
  else
    puts 'No more retries'
  end
end

Drag options to blanks, or click blank then click option'

Dbreak

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'tries' instead of 'max_retries' causes wrong retry limit.

Using 'break' instead of 'retry' stops retries prematurely.

Use max_retries to limit retries and retry to restart the block.

5fill in blank

hard

Fill all three blanks to retry only when error message is 'Timeout', up to 3 times, and print attempts.

Ruby

max_attempts = 3
count = 0
begin
  count += 1
  puts "Attempt #{count}"
  raise 'Timeout' if count < max_attempts
rescue => e
  if e.message == [1] && count < [2]
    puts 'Retrying due to timeout'
    [3]
  else
    puts 'Stopping retries'
  end
end

Drag options to blanks, or click blank then click option'

A"Timeout"

Bmax_attempts

Cretry

D"Error"

Attempts:

3 left

💡 Hint

Common Mistakes

Using wrong error message string causes no retry.

Not limiting retries causes infinite loop.

Using 'break' instead of 'retry' stops retries.

Compare error message with "Timeout", limit retries with max_attempts, and use retry to restart.
