How to generate timestamp in python

When developing web programs in Python, you need to call third-party related interfaces. When calling, you need to sign the request. Need to use unix timestamp.

In python, many methods introduced on the Internet get a timestamp of 10 digits. The default in java is 13 bits (milliseconds, milliseconds).

The following introduces the method of obtaining the timestamp in python:

1. 10 Timestamp obtaining method:

>>> import time
>>> t = time.time()
>>> print t
1436428326.76
>>> print int(t)
1436428326
>>>

The forced conversion is directly removed Decimal places.

2. How to obtain the 13-digit timestamp:

(1) Python time by default The stamp is a float output in seconds.

>>> 
>>> import time
>>> time.time()
1436428275.207596
>>>

Obtain a 13-digit timestamp by converting seconds to milliseconds:

import time
millis = int(round(time.time() * 1000))
print millis

round() is rounded.

(2)

import time
current_milli_time = lambda: int(round(time.time() * 1000))
Then:
>>> current_milli_time()
1378761833768

13-digit timestamp converted into time:

>>> import time
>>> now = int(round(time.time()*1000))
>>> now02 = time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(now/1000))
>>> now02
'2019-06-21 09:53:17'
