Question

如何使用正则表达式匹配一个只能包含17个字母数字字符的字符串，并且不包含字母＆＃39; q＆＃39; ＆＃39;○＆＃39;和＆＃39;我＆＃39;。又名，只有字母和数字，但不是＆＃39; q＆＃39; ＆＃39;○＆＃39;和＆＃39;我＆＃39;。

可以分别在python中完成两个条件：

[A-Z0-9] {17}
[^一种或多种QoI]

所以除了指定有效的字符间隔或者使用AND将两个条件组合在一起之外，在python中有任何更优雅的方法，你可以实际指定你想要包含的字符，同时排除那些你不想要的字符。 Java中的[a-z0-9&&[^qoi]]

（例如，我想排除10个随机字母，指定每个间隔[a-bd-eh-ow-......]

如果没有这种方式，我只能接受python正则表达式的现实。

感谢您的帮助！埃里克

你可以把任何你想要的东西放在方括号中。因此，例如，要匹配除q，o和i之外的任何字母，您可以使用：

<!DOCTYPE html>
<html lang="en">

<head>
  <title>Test</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
  <link rel="stylesheet" href="css.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>

您还可以指定多个范围，以便更明显地跳过哪些字符：

#wrapper{
  display: inline-block;
  white-space: nowrap;
}
.square{
  height: 100px; 
  width: 100px; 
  border: none; 
  border-radius:0px;
  vertical-align: top;
  margin-left: -5px;
}
.Category{
  height: 100px; 
  width: 200px; 
  border: none; 
  border-radius:0px; 
  background: white;
  text-align: right;
  vertical-align: top;
}

.topRow{
  margin: 10px 100px 50px 200px;
  display: inline-block;
  white-space: nowrap;
}
.tableRow{
  margin: 0px 100px 0px 0px;
  display: inline-block;
  white-space: nowrap;
}
.bottomRow{
  margin: 50px 100px 50px 200px;
  display: inline-block;
  white-space: nowrap;
}
.wrapper span {
   float: left;
   clear: left;
}

.modal-dialog {
   width: 75%;
   height: 70%;
}
.modal-body{
    height: 250px;
    overflow-y: auto;
    white-space: pre-wrap;
}

可能有更优雅的方法，但基本概念是相同的：只在[0-9abcdefghjklmnprstuvwxyz]内放置你想要匹配的字符。

Answer 2

以下是两个选项：

分别检查每个条件

使用两个正则表达式并确保它们都匹配。这与你的java示例非常相似。

import re
test_case = "asdFghijalkdjflkjsd"
re.match("^[A-Za-z0-9]{17}$", test_case) and re.match("^[^qoi]+$", test_case)

明确列出合法

列出所有合法的字母数字字符，应排除q，i和o

import re
test_case ="12345a78901234567"
re.match("^[ABCDEFGHJKLMNPRSTUVWXYZabcdefghjklmnprstuvwxyz0-9]{17}$", test_case)

当然，这可以使用范围来缩小，例如A-HJ-NPR-Z，等。
