Convert a list of integers to string
提问by Mira Mira
I want to convert my list of integers into a string. Here is how I create the list of integers:
我想将我的整数列表转换为字符串。这是我创建整数列表的方法：
new = [0] * 6
for i in range(6):
new[i] = random.randint(0,10)
Like this:
像这样：
new == [1,2,3,4,5,6]
output == '123456'

There's definitely a slicker way to do this, but here's a very straight forward way:
肯定有一种更巧妙的方法可以做到这一点，但这里有一个非常直接的方法：
mystring = ""
for digit in new:
mystring += str(digit)

With Convert a list of characters into a stringyou can just do
使用Convert a list of characters into a string你可以做
''.join(map(str,new))

Coming a bit late and somehow extending the question, but you could leverage the arraymodule and use:
来得有点晚，并以某种方式扩展了问题，但您可以利用该array模块并使用：
from array import array
array('B', new).tobytes()
b'\n\t\x05\x00\x06\x05'
In practice, it creates an array of 1-byte wide integers (argument 'B') from your list of integers. The array is then converted to a string as a binary data structure, so the output won't look as you expect (you can fix this point with decode()). Yet, it should be one of the fastest integer-to-string conversion methods and it should save some memory. See also documentation and related questions:
实际上，它会'B'从您的整数列表中创建一个 1 字节宽的整数数组（参数）。然后将数组转换为字符串作为二进制数据结构，因此输出不会像您预期的那样（您可以使用 修复这一点decode()）。然而，它应该是最快的整数到字符串转换方法之一，它应该可以节省一些内存。另请参阅文档和相关问题：

You can loop through the integers in the list while converting to string type and appending to "string" variable.
您可以循环遍历列表中的整数，同时转换为字符串类型并附加到“字符串”变量。
for int in list:
string += str(int)

two simple ways of doing this
两种简单的方法来做到这一点
"".join(map(str, A))
"".join([str(a) for a in A])
