# 1 - Get the current day, month, year, hour, minute and timestamp from datetime module
now = datetime.now()
# ":02d" Adds 0-padding (0=pad with 0, 2=width of 2, d=decimal integer (no decimal points))

# 3 - Today is 5 December, 2019. Change this time string to time.
print(datetime.strptime("5 December, 2019", "%d %B, %Y"))

# 4 - Calculate the time difference between now and new year.

# 5 - Calculate the time difference between 1 January 1970 and now.
date_5 = datetime.strptime("1, January, 1970", "%d, %B, %Y")
print(f"Time difference between now ({now.strftime("%Y-%m-%d %H:%M:%S")}) and {date_5.strftime("%Y-%m-%d %H:%M:%S")} = {now - date_5})")

# 6 - Think, what can you use the datetime module for? Examples:
# To get a timestamp of any activities in an application

    print(f"User logged in at: {datetime.now().strftime('%H:%M:%S')}")
