import time

print(dir(time))    # print components of "time" module
print()

print(time.time(), "\n")    # print time as numeric value calculated from 1970, 1, 1, 00:00:00

t = time.ctime()    # Sat Aug  7 01:19:22 2021
print(t)
time.sleep(1)    # pause for 1 seconds
print(t.split(' ')[-1])    # print 'year' only
print(t.split(' ')[-2].split(':')[-3])    # print "hour" only

now = time.localtime()
filename = "log_%02d%02d%02d_%02d-%02d-%02d.txt" % (now.tm_year, now.tm_mon, now.tm_mday, now.tm_hour, now.tm_min, now.tm_sec)
print("\n", filename)
