Theindex()method is used to find the index of the first occurrence of a specified element in a list. This method is particularly useful when you need to know the position of a specific element within a list. Here’s an example of how to use theindex()method to find the index of the...
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...

方法find()允许我们以参数形式传入某一字符或字符串,它查找返回原字符串中传入字符或子字符串出现的最低索引号。我们IDLE上瞧瞧就清楚啦。 >>>intf='interface GigabitEthernet10/0/3'# 原字符串>>>intf.find('GigabitEthernet')# 查找子字符串,返回第一次匹配的最低索引值,其实就是G的索引值。10>>>intf[i...
