NumPy: Get the dates of yesterday, today and tomorrow
NumPy DateTime: Exercise-2 with Solution
Write a NumPy program to get the dates of yesterday, today and tomorrow.
Sample Solution:-
Python Code:
import numpy as np
yesterday = np.datetime64('today', 'D') - np.timedelta64(1, 'D')
print("Yestraday: ",yesterday)
today = np.datetime64('today', 'D')
print("Today: ",today)
tomorrow = np.datetime64('today', 'D') + np.timedelta64(1, 'D')
print("Tomorrow: ",tomorrow)
Sample Output:
Yestraday: 2017-03-24 Today: 2017-03-25 Tomorrow: 2017-03-26

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
