python time practice

import time
from datetime import date
today = date.today()
mydate=date(2007, 12, 5)
print(mydate)
print(today)
print(type(mydate))
print(date.fromtimestamp(time.time()))
print(time.time())
print(dir(time))
print(time.tzname)

How To Convert Timestamp To Date and Time in Python


There are multiple ways how you can convert timestamp to human readable form in Python. For this conversion you may either use module datetime or time.

Using module datetime

Module datetime provides classes for manipulating date and time in more object oriented way.

import datetime
readable = datetime.datetime.fromtimestamp(1521069137).isoformat()
print(readable)
# 2018-03-15T00:12:17+01:00

Using module time

Another possibility to use function ctime from module time.

import time
readable = time.ctime(1521069137)
# Thu Mar 15 00:12:17 2018

Formatting

For custom human readable format you may use function strftime.

import time
ts = time.gmtime()
print(time.strftime("%Y-%m-%d %H:%M:%S", ts))
# 2018-03-15 00:12:17

print(time.strftime("%x %X", ts))
# 03/15/18 00:12:17

# Iso Format
print(time.strftime("%c", ts))
# Thu Mar 15 00:12:17 2018

# Unix timestamp
print(time.strftime("%s", ts))
# 1521069137

%wWeekday as a decimal number [0(Sunday),6].
%WWeek number of the year (Monday as the first day of the week) as a decimal number [00,53]. All days in a new year preceding the first Monday are considered to be in week 0.
%xLocale’s appropriate date representation.

%yYear without century as a decimal number [00,99].
%YYear with century as a decimal number.
%ZTime zone name (no characters if no time zone exists).

How To Get Current Timestamp In Python


There is multiple ways how to get current timestamp in Python. If you want to get timestamp in Python, you may use functions from modules timedatetime, or calendar.

Using module time

Module time is providing various time related functions. One of them is time which return number of seconds since the epoch.

import time;
ts = time.time()
print(ts)
# 1521068985.78  

Using module datetime

Module datetime provides classes for manipulating date and time in more object oriented way. One of them is datetime.datetime.now which return number of seconds since the epoch.

import datetime;
ts = datetime.datetime.now().timestamp()
print(ts)
# 1521068985.78

Using module calendar

Another way how to get current timestamp is to combine multiple functions from multiple modules. Python provides also calendar module. In this case we will use function calendar.timegm to convert tuple representing current time.

import calendar;
import time;
ts = calendar.timegm(time.gmtime())
print(ts)
# 1521068985
