Compound if else statement

[deanhystad]

import pandas as pd
import random
from time import time

states = ["Morning", "Afternoon", "Evening", "Night"]
df = pd.DataFrame({"state": random.choices(states, k=10000000)})

a = time()
for i, state in enumerate(states, start=1):
    df.loc[df["state"] == state, ["state"]] = i

print(time() - a)

Output:
1.6639153957366943

Almost twice as fast as calling a functon/lambda. Nowhere near as fast as passing a dictionary
