How to use sample() method to shuffle an array In Python
Here we are using the sample method from the random library to shuffle an array.
Python3
# Import required moduleimport randomimport array# Assign array# here q indicates that the array# contains signed integerarr = array.array('q', [1, 2, 3, 4, 5, 6])# Display original arrayprint("Original array: ", arr)# Shuffle array# Here sample() returns a list, so we# are typecasting list into arrayarr = array.array('q', random.sample(list(arr), 6))# Display shuffled arrayprint("Shuffled array: ", arr) |
Output:
Original array: array('q', [1, 2, 3, 4, 5, 6])
Shuffled array: array('q', [6, 3, 2, 1, 5, 4])
