💡 Hint

Common Mistakes

Using '<' instead of '>' for the second blank.

The comprehension accesses the version attribute of info and filters for versions greater than 1.0.

💡 Hint

Common Mistakes

Using 'package' instead of 'pkg' in the loop variable.

Using 'pkg' instead of 'pkg.upper()' for the key.

The comprehension maps the uppercase package name (pkg.upper()) to its info, iterating over pkg and info.
