we have to call it on the string that’ll be used for joining. In this case, we’re using a string with a space in it. The method receives a list of strings and returns one string with each of the strings joined by the initial string. Let’s check its functionality with...

Functions allow us to conserve programming code from duplication by storing it as reusable blocks for later use. When working on a large program, breaking it into smaller functions helps to keep the code clean and improve readability. It also makes the program reusable, which prevents repeating ...
Square Every Digit 思路: number 可以循环么? 转换数据类型 然后直接循环 point: 生成新的字符两种方法 1 2 3 Mystring="" foriinstr() Mystring+=str( ) 1 ' '.join(str()foriinstr(s)) 总结: string 可以用来循环, 生成string的命令, string的拆分, reverse() 命令进行reverse item ...
