问题：Python将元组转换为字符串

我有一个这样的字符元组：

('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e')

我如何将其转换为字符串，使其类似于：

'abcdgxre'

I have a tuple of characters like such:

('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e')

How do I convert it to a string so that it is like:

'abcdgxre'

用途str.join：

>>> tup = ('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e')
>>> ''.join(tup)
'abcdgxre'
>>>
>>> help(str.join)
Help on method_descriptor:

join(...)
    S.join(iterable) -> str

    Return a string which is the concatenation of the strings in the
    iterable.  The separator between elements is S.

Use str.join:

>>> tup = ('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e')
>>> ''.join(tup)
'abcdgxre'
>>>
>>> help(str.join)

这是使用联接的一种简单方法。

''.join(('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e'))

here is an easy way to use join.

''.join(('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e'))

这有效：

''.join(('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e'))

它将生成：

'abcdgxre'

您还可以使用定界符（例如逗号）来生成：

'a,b,c,d,g,x,r,e'

通过使用：

','.join(('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e'))

This works:

''.join(('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e'))

It will produce:

'abcdgxre'

You can also use a delimiter like a comma to produce:

'a,b,c,d,g,x,r,e'

By using:

','.join(('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e'))

最简单的方法是像这样使用join：

>>> myTuple = ['h','e','l','l','o']
>>> ''.join(myTuple)
'hello'

之所以有效，是因为您的定界符实际上什么都没有，甚至没有空格：”。

Easiest way would be to use join like this:

>>> myTuple = ['h','e','l','l','o']
>>> ''.join(myTuple)
'hello'

This works because your delimiter is essentially nothing, not even a blank space: ”.
