NumPy: Calculate the absolute value element-wise
NumPy Mathematics: Exercise-7 with Solution
Write a NumPy program to calculate the absolute value element-wise.
import numpy as np x = np.array([-10.2, 122.2, .20]) print("Original array:") print(x) print("Element-wise absolute value:") print(np.absolute(x))
Original array: [ -10.2 122.2 0.2] Element-wise absolute value: [ 10.2 122.2 0.2]

Python: Tips of the Day
timeit library is great for timing Python execution times. Just pass a function in string format to timeit.timeit() method and it will carry out 1 million executions to report the minimum time the code takes.
Its very useful to compare small code pieces and different functions but can be sluggish with big code.
Check out the example below demonstrating the execution time difference between 2 very similar list comprehension methods in Python:
import timeit lst1='''list(range(100))''' lst2='''[i for i in range(100)]''' a=timeit.timeit(lst1) b=timeit.timeit(lst2) print(a, b, sep="------")
