列表中的python项目已添加到字符串

Question

I am trying to concatenate items in a list onto a string.

list = ['a', 'b', 'c', 'd']
string = ''
for i in list:
    string.join(str(i))

Answer 1

You don't need a loop:

items = ['a', 'b', 'c', 'd']
result = "".join(items)

Note that it's a bad idea to use list as the name of a variable, because that prevents you from using list to mean the built-in type.

Answer 2

Is this what you are looking for?

>>> my_list = ['a', 'b', 'c', 'd']
>>> "".join(my_list)
'abcd'

You shouldn't use list as a variable name, since this will shadow the built-in class list .
