redundant-u-string-prefix / W1406

Message emitted:

The u prefix for strings is no longer necessary in Python >=3.0

Description:

Used when we detect a string with a u prefix. These prefixes were necessary in Python 2 to indicate a string was Unicode, but since Python 3.0 strings are Unicode by default.

Problematic code:

def print_fruit():
    print(u"Apple")  # [redundant-u-string-prefix]

Correct code:

def print_fruit():
    print("Apple")
