Write a Python program to select an item randomly from a list. Use random.choice() to get a random element from a given list. Example - 1 : Example - 2 : Example - 3 : Sample Solution-1: Python Code: # Import the 'random' module, which provides functions for generating random value...
random.sampleis similar torandom.choice, the main difference being that you can specify the number of random elements you want. In the above code snippet, I got two random Twitter user names.random.samplereturns a list. In some cases, you might want the same random element(s) to be retur...

To select distinct elements across multiple DataFrame columns, we need to check if there are any duplicates in the DataFrame or not and if there is any duplicate then we need to drop that particular value to select the distinct value. For this purpose, we will use DataFrame['col'].uniqu...

flinksessionjob 执行python flink keyselector 场景 在keyby之后,通过简单选择了key之后(randomInt,取模运算),会出现下游算子接收数据不均衡的情况,即多个slot中可能只会有部分slot在使用。 在%4,下游算子并行度为4的情况下可能只有个slot在使用。首先排除key分布不均的情况,模4之后只会产生四个值,0,1,2,3。
