- Easily load or dump and json/pkl/csv/npy file:
import penut.io as pio data = pio.load('data.json') data = pio.load('data.pkl') data = pio.load('data.csv') data = pio.load('data.npy') pio.dump(data, 'data.json') pio.dump(data, 'data.pkl') pio.dump(data, 'data.csv') pio.dump(data, 'data.npy')
- Easily measure the execution time of code:
import time from penut import TimeCost with TimeCost('Sleep Time'): time.sleep(1) # Output: Sleep Time: 1.000262s # With custom format fmt = lambda msg, tts: f'Hello {msg}, you cost {tts:.2f}s!!' with TimeCost('Custom Format', verbose_fmt=fmt): time.sleep(1) # Output: Hello Custom Format, you cost 1.00s!!
- Easily convert
datetime.timedelta
to string:from penut import td2s from datetime import datetime a = datetime(2021, 1, 6, 11, 32, 23) b = datetime(2021, 1, 7, 12, 38, 17) d = b - a print(td2s(d)) # 62:17:54 fmt = lambda h, m, s: f'{h}h{m}m{s}s' print(td2s(d, fmt)) # 62h17m54s
