比如路由器和交换机中用来警告非授权用户非法访问设备后果的MOTD(Message of The Day)之类的旗标(banner)配置,此类文本内容通常比较长且需要换行,这时用三引号来表示该文本内容就是最好的选择,举例如下: >>>motd=''' ---... Warning: You are connected to the Cisco systems, Incorporated network... Unautho...
标识符应既要简短又具有描述性，例如：name 比 n 好，name_length 比 length_ of_persongs_name 好。
Strings can beconcatenatedto build longer strings using the plus sign and also they can bemultipliedby a number, which results in the continuous repetition of the string as many times as the number indicates. Also, if we want to find out thelengthof the string, we simply have to use thelen...
Variable Length Arguments in Python allow functions to accept a flexible number of parameters. Denoted by an asterisk (*) before the parameter name, these arguments enable passing any number of values, creating versatile and dynamic functions. This feature enhances code adaptability by accommodating di...
Using a for loop, traverse through all the data elements and after encountering every element, increment the counter variable by 1. 使用for循环,遍历所有数据元素,遇到每个元素后,将计数器变量加1。 Thus, the length of the array will be stored in the counter variable as the variable will represent...

To print the length of a string, use the len() function. len(var) Let’s see how you can extract characters from two strings and generate a new string. var1 = “It’s Sunday” var2 = “Have a great day” The new string should say, “It’s a great Sunday” and be stored in...
Subsequent characters can be letters, numbers, or underscores. Case-sensitive: age, Age, and AGE are considered different variables. Can be of any reasonable length. Reserved words (like if, for, while, etc.) cannot be used as variable names.Good...
