💡 Hint

Common Mistakes

Using '-l' which is not a valid option for limiting commits.

Using '-c' or '-m' which have different meanings.

The -n option limits the number of commits shown. So git log -n 3 shows the last 3 commits.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps commit hashes to their messages for commits with messages longer than 10 characters.

Git

{commit.[1]: commit.[2] for commit in commits if len(commit.message) > 10}

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

Ahexsha

Bauthor

Cmessage

Ddate

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'author' or 'date' instead of hash or message.

Confusing message with author name.

In Git Python libraries, hexsha is the commit hash and message is the commit message.

5fill in blank

hard

Fill all three blanks to filter commits with messages containing 'fix' and create a dictionary of commit hashes to authors.

Git

{commit.[1]: commit.[2] for commit in commits if 'fix' in commit.[3].lower()}

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

Ahexsha

Bauthor

Cmessage

Dcommitter

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'committer' instead of 'author' for the second blank.

Checking 'fix' in author or committer instead of message.

We use hexsha for commit hash, author for who made the commit, and check if 'fix' is in the message.
