how to covert date to milisecond in python

Question

I have a date in this format 04-07-2018 the following Javascript produces

const date1 = new Date("04-07-2018").getTime();
date1; // 1523084400000

how do I parse the date and convert them to milliseconds in python

We can perform this in three steps:

first we convert the string to a datetime object;
next we calculate the difference between that datetime object and the first of January, 1970;
we calculate this difference in seconds, and then multiply it with 1000.

For example:

from datetime import datetime

def total_millis(text):
    dt = datetime.strptime(text, '%m-%d-%Y')
    return 1000 * (dt - datetime(1970, 1, 1)).total_seconds()

This implementation however is timezone independent, whereas the JavaScript version depends on the timezone.

The JavaScript getTime() method returns the number of milliseconds since January 1, 1970 00:00:00.

You can use datetime but you should compute it with a deltatime object since according to this Python doesn't guarantee any particular epoch time

import datetime
delta = datetime.datetime(2018, 4, 7) - datetime.datetime(1970, 1, 1)
milliseconds = delta.total_seconds()*1000 # 1523059200000.0
