用户输入字符串包含某些字符测试 [英] User-input string contains certain character test

问题描述

全部，

我将为用户输入一个长度为10,14,17个字符或包含逗号（任意长度）的字符串。脚本从那里开始，具体取决于输入的长度。当我使用各种可接受的长度或包含逗号进行测试时，脚本可以正常工作。但是，如果我输入一个不可接受的长度（并且没有逗号），我会继续获得''到LL模型''的打印语句而不是''不可接受的条目 - 拯救！''的声明。我做错了什么？

All,
I will have a user input a string that is either 10, 14, 17 characters long, or contains a comma (of any length). The script proceeds from there depending on the length entered. When I test with the various acceptable lengths or containing a comma, the script works. However, if I put in an unacceptable length (and without a comma), I keep getting the ''to LL model'' print statement instead of the ''Unacceptable entry -- bailing out!'' statement. What am I doing wrong?

正如另一个例子，我走了另一条路线，使用正则表达式做了以下，看起来工作正常：

Just as another example, I went another route, using Regular Expressions and did the following, which seemed to work fine:
