dict-iter-missing-items / E1141

Message emitted:

Unpacking a dictionary in iteration without calling .items()

Description:

Emitted when trying to iterate through a dict without calling .items()

Problematic code:

data = {"Paris": 2_165_423, "New York City": 8_804_190, "Tokyo": 13_988_129}
for city, population in data:  # [dict-iter-missing-items]
    print(f"{city} has population {population}.")

Correct code:

data = {"Paris": 2_165_423, "New York City": 8_804_190, "Tokyo": 13_988_129}
for city, population in data.items():
    print(f"{city} has population {population}.")
