Combine elements in a string array. Instead of spaces, insert different pieces of text between the strings in str. Create a string array. Get str = ["x","y","z"; "a","b","c"] str = 2x3 string "x" "y" "z" "a" "b" "c" Concatenate the strings with dashes between the...

Concatenate any number of strings. The string whose method is called is inserted in between each given string. The result is returned as a new string. Example: '.'.join(['ab', 'pq', 'rs']) -> 'ab.pq.rs' """pass 看了构造就知道函数内需要传入可迭代对象,所以我们先传入一个列表演示...
