Practice - 5 Tasks

1fill in blank

easy

💡 Hint

Common Mistakes

Using 'shallow' without '=' causes syntax error.

Using 'depth 1' without '=' is invalid syntax.

Using 'single-branch' clones only one branch but not necessarily shallow.

The --depth=1 option clones only the latest commit, making cloning faster for large repos.

medium

Complete the Git command to list all branches in a large repository without fetching all remote data.

Git

git branch --[1]

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

Cverbose

Dlist

💡 Hint

Common Mistakes

Using 'all' lists local and remote branches but may be slow.

Using 'verbose' shows extra info but not limited to remote branches.

Using 'list' is not a valid option.

The --remote option lists remote branches without fetching all data, useful for large repos.

3fill in blank

hard

Fix the error in the Git command to fetch only a specific branch from a large repo.

Git

git fetch origin [1]

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

Afeature_branch

Bfeature/branch

Cfeature-branch

Dfeature branch

Attempts:

3 left

💡 Hint

Common Mistakes

Using spaces in branch names causes errors.

Using underscores instead of dashes is invalid if branch name uses dashes.

Using slashes may be valid but depends on actual branch name.

Branch names use dashes, not spaces or underscores. 'feature-branch' is correct syntax.

4fill in blank

hard

Fill both blanks to create a shallow clone of only the main branch in a large repo.

Git

git clone --[1]=1 --[2] main https://example.com/large-repo.git

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

Adepth

Bbranch

Csingle-branch

Dshallow

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'shallow' instead of 'single-branch' causes errors.

Omitting '=' in depth option causes syntax errors.

Using 'branch' without 'single-branch' clones all branches.

--depth=1 limits history, and --single-branch clones only the specified branch.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps branch names to their latest commit hashes for branches with names longer than 5 characters.

Git

branch_commits = [1]: [2] for [3] in branches if len([3]) > 5

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

Dbranches

3 left

💡 Hint

Common Mistakes

Using 'branches' as key causes errors.

Using 'branch' as value without indexing causes errors.

Not filtering by length causes large output.

This comprehension maps each branch name to its commit hash, filtering by branch name length.
