3. Start saving time:

import scrat as sc
import time

@sc.stash()
def expensive_function(param_1):
    time.sleep(3)
    return param_1

expensive_function(1)  # <- function called
expensive_function(1)  # <- function not called the result is recovered from stash
expensive_function(2)  # <- function called again beacuse the parameters changed

Features

• Automatically saves any result using pickle
• Automatically saves pandas DataFrames as parquet
