python随机从列表中取出一个值,如何从列表中打印随机值名称？（python）

Let&＃39;s say:

list&＃61;["A","B","C"]

listitem &＃61; random.randint(0,2)

I typed:

print listitem

but it gives a number and I&＃39;d like a letter?

How can I do this?

解决方案

You need to use the random index to reference the item in your list.

>>> import random

>>> list&＃61;["A","B","C"]

>>> listitem &＃61; random.randint(0,len(list))

>>> list[listitem]

&＃39;A&＃39;

>>> listitem &＃61; random.randint(0,len(list))

>>> list[listitem]

&＃39;B&＃39;

Or, if you don&＃39;t care about the index, just select an item at random using the random.choice() routine:

>>> random.choice(list)

&＃39;B&＃39;

>>> random.choice(list)

&＃39;B&＃39;

>>> random.choice(list)

&＃39;A&＃39;

>>> random.choice(list)

&＃39;C&＃39;
