Now that we have created the example list of strings, we will examine ways of determining if the search string is present in the list. The search string is defined below:search_string = "radio"Let’s now find it
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...
s.find(sub [,start [,end]]) -> int 检测 sub 是否包含在 string 中,如果 start 和 end 指定范围,则检查是否包含在指定范围内,如果是返回开始的索引值,否则返回-1 s.rfind(sub [,start [,end]]) -> int 右边开始查找.返回字符串最后一次出现的位置(从右向左查询),如果没有匹配项则返回-1。
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。
