如何将列表中的元素转换为一个字符串？

Question

community,

I have a list, that consists of different strings (sentences, words...) I would like to join them all together to one string. I tried:

kafka = ['Das ist ein schöner Tag.', '>>I would like some ice cream and a big cold orange juice!',...]
''.join(kafka) #but strings stay the same as before

Answer 1

You need to do:

kafka = ['Das ist ein schöner Tag.', '>>I would like some ice cream and a big cold orange juice!',...]
s = ''.join(kafka)

s now contains your concatenated string.

Answer 2

Basically you are on the right track, but you need to assign the join operation to a new variable or use it directly. the original list won't be affected.

concatenate them with or without any spaces in between:

no_spaces = ''.join(kafka)
with_spaces = ' '.join(kafka)

print no_spaces
print with_spaces

Answer 3

The reason is that

''.join(kafka)

returns the new string without modifying kafka. Try:

my_string = ''.join(kafka)

And if you want spaces between sentences then use:

my_string = ' '.join(kafka)

Answer 4

''.join(kafka) returns a string. To make use of it, store it into a variable:

joined = ''.join(kafka)
print joined

Note: you may want to join with a space ' ' instead.

Answer 5

You can join it using ,

Assuming your list is

['Das ist ein schöner Tag.', '>>I would like some ice cream and a big cold orange juice!']

>>> kafka = ['Das ist ein schöner Tag.', '>>I would like some ice cream and a big cold orange juice!']
>>>' '.join(kafka)

Output :

'Das ist ein sch\xf6ner Tag. >>I would like some ice cream and a big cold orange juice!'
