Errors in string formatting operations

Last modified: 03 December 2024

Reports errors in string formatting operations.

Example 1:

"Hello {1}".format("people")

Example 2:

def bar():
    return 1


"%s %s" % bar()

As a fix, you need to rewrite string formatting fragments to adhere to the formatting syntax.
