NumPy: Convert numpy datetime64 to Timestamp
NumPy DateTime: Exercise-7 with Solution
Write a NumPy program to convert numpy datetime64 to Timestamp.
Sample Solution:-
Python Code:
import numpy as np
from datetime import datetime
dt = datetime.utcnow()
print("Current date:")
print(dt)
dt64 = np.datetime64(dt)
ts = (dt64 - np.datetime64('1970-01-01T00:00:00Z')) / np.timedelta64(1, 's')
print("Timestamp:")
print(ts)
print("UTC from Timestamp:")
print(datetime.utcfromtimestamp(ts))
Sample Output:
Current date: 2017-04-01 08:01:12.722055 Timestamp: 1491033672.72 UTC from Timestamp: 2017-04-01 08:01:12.722055

Python: Tips of the Day
Decompose a collection:
Assume we have a function that returns a tuple of two values and we want to assign each value to a separate variable. One way is to use indexing as below:
abc = (5, 10) x = abc[0] y = abc[1] print(x, y)
Output:
5 10
There is a better option that allows us to do the same operation in one line.
x, y = abc print(x, y)
Output:
5 10
It can be extended to a tuple with more than 2 values or some other data structures such as lists or sets.
x, y, z = {1, 2, 3} print(x, y, z) x, y, z = ['a', 'b', 'c'] print(x, y, z)
Output:
1 2 3 a b c
