open-alias (UP020)

Derived from the pyupgrade linter.

Fix is sometimes available.

What it does

Checks for uses of io.open.

In Python 3, io.open is an alias for open. Prefer using open directly, as it is more idiomatic.

import io

with io.open("file.txt") as f:
    ...

Use instead:

with open("file.txt") as f:
    ...

This rule's fix is marked as safe, unless the expression contains comments.
