In addition,Python’s strings support the sequence type methods described in the Sequence Types — str, unicode, list, tuple, buffer, xrange section. To output formatted strings use template strings or the % op

/""". This string ends in a newline. """ 三重撇号字符串也可以用三个单撇号,没有任何语义差别。多行的字符串常量可以直接连接起来,字符串常量之间用空格分隔则在编译时可以自动连接起来,这样可以把一个长字符串连接起来而不需要牺牲缩进对齐或性能,不象用加号连接需要运算,也不象字符串串内的换行其行首...
In this example, the variable my_letters is a list of strings. We want to print these letters, each separated by a tab, to a text file. The one complication in this example is ensuring that the letters are printed with tabs between them and a newline character (not a tab) is placed...
