# Create example datetimes
start = datetime(2017, 10, 8, 23, 46, 47)
end = datetime(2017, 10, 9, 0, 10, 57)

# Subtract datetimes to create a timedelta
duration = end - start

# Subtract datetimes to create a timedelta
print(duration.total_seconds())

1450.0

Crearea obiectelor timedelta

# Import timedelta
from datetime import timedelta

# Create a timedelta
delta1 = timedelta(seconds=1)

print(start)

2017-10-08 23:46:47

# One second later
print(start + delta1)

2017-10-08 23:46:48

# Create a one day and one second timedelta
delta2 = timedelta(days=1, seconds=1)

print(start)

2017-10-08 23:46:47

# One day and one second later
print(start + delta2)

2017-10-09 23:46:48

# Create a negative timedelta of one week
delta3 = timedelta(weeks=-1)

print(start)

2017-10-08 23:46:47

# One week earlier
print(start + delta3)

2017-10-01 23:46:47

# Same, but we'll subtract this time
delta4 = timedelta(weeks=1)

print(start)

2017-10-08 23:46:47

# One week earlier
print(start - delta4)

2017-10-01 23:46:47
