Python：如何在将列表中的项目连接到字符串时删除格式？

Question

Good morning, all:

I'm working on a small Python program which matches together small strings in order to make up fictional company names. The name segments are stored in three lists, and a random string from each list is chosen each time a new name is requested. For example, the program might pick "Eli", "rce" and "Softworks" from the three lists, which would give me "Elirce Softworks".

seg1 = namesegs1[random.randint(0, seg1_length)]
seg2 = namesegs2[random.randint(0, seg2_length)]
seg3 = namesegs3[random.randint(0, seg3_length)]
new_name = "{0}{1} {2}".format(seg1, seg2, seg3)

However, the code actually returns ['Eli']['rce'] ['Softworks']. It makes sense, given that it's joining items from lists, but I don't see why these can't be removed in some way or another.

Here's one way I've made it work:

new_name = new_name.replace("'", "")
new_name = new_name.replace(",", "")
new_name = new_name.replace("[", "")
new_name = new_name.replace("]", "")

That gets rid of the formatting nicely, but it's less than satisfactory and it feels like I'm doing it wrong. Is there a better way to be going about this?

Many thanks for your time.

Answer 1

It looks like namesegs1 is a list of lists rather than a list of strings.

What do you get with the following?

new_name = "{0}{1} {2}".format(seg1[0], seg2[0], seg3[0])

By the way, use random.choice(namesegs1) to select a random item from your list, rather than that thing you've done with random.randint .

Answer 2

Are you familiar with Python string join functionality? For me it sounds like what you need.

Answer 3

Suppose your logic with the randomizer generates an input list as: input_list = [['Eli'],['rce'],['Softworks']]

the following code will give you what you need:

input_list = [i[0] for i in input_list]
''.join(input_list)
