This selects 3 random students from the list. Each run produces different results like ['David', 'Alice', 'Charlie']. Best PracticesBackup Data: Make a copy if you need the original order. Associative Arrays: Be aware key-value pairs are lost. Randomness: For cryptography, use ...
Each input file contains one test case. For each case, the first line contains a positive integerK(≤20) which is the number of repeat times. Then the next line contains the given order. All the numbers in a line are separated by a space. Output Specification: For each test case, prin...

Is your intention to shuffle the elements while maintaining their keys, resulting in a shuffled order when iterating over them? This can be accomplished by converting the array into a list of pairs, with each pair consisting of a key and its corresponding element. ...

我以为可以使用random.shuffle方法,但是当列表中包含对象时,这似乎失败了。是否有一种用于改组对象的方法或解决此问题的另一种方法? import random class A: foo = "bar" a1 = a() a2 = a() b = [a1, a2] print(random.shuffle(b)) 这将失败。 python list random shuffle ...
Declare a separate list to store the output achieved. Step 2− Choose an element i randomly in the input sequence and add it onto the output list. Mark the element i as visited. Step 3− Repeat Step 2 until all the element in the finite sequence is visited and added onto the ...
