This article mainly introduces how python merges the list into strings, which is very detailed and has a certain reference value. Friends who are interested must read it!

Merge the list into a string

Str_list = ['hello',' world', 'good'] str1 = "" .join (str_list)

This method is more efficient than the traditional "string 1" + "string 2" method, because concatenating strings with the + sign produces new objects each time, resulting in greater memory overhead. And join won't.

Through the string join method, we can concatenate all the string elements in a list to form a new string.
