Question

我希望将 lat和lng 存储到某个变量中。这是html文件中匹配的模式。我使用正则表达式来匹配该模式，我从页面获取那些匹配的值。

但是如何将 match.groups（）值存储到变量？

这是我的代码。

import re

pattern = re.compile("(l[an][gt])(:\s+)(\d+\.\d+)")
for i, line in enumerate(open('C:\hile_text.html')):
    for match in re.finditer(pattern, line):
        print 'Found on line %s: %s' % (i+1, match.groups())

输出：

在第3218行找到：（＆＃39; lat＆＃39;，＆＃39;：＆＃39;，＆＃39; 21.244791＆＃39;）
在第3218行找到：（＆＃39; lng＆＃39;，＆＃39;：＆＃39;，＆＃39; 81.649491＆＃39;）

我可以打印这些值，但我想将这些值存储在某个变量中。

Plzz帮助我。

这是文件

以下的内容能满足您的需求吗？

import re

latitude = r"lat:\s+(\d+\.\d+)"
longitude = r"lng:\s+(\d+\.\d+)"

for i, line in enumerate(open('C:\hile_text.html'), start=1):
    match = re.search(latitude, line)
    if match:
        lat = match.group(1)
        print('Found latitude on line %s: %s' % (i, lat))

    match = re.search(longitude, line)
    if match:
        lng = match.group(1)
        print('Found longitude on line %s: %s' % (i, lng))

<强>输出

> python test.py
Found latitude on line 4: 21.25335
Found longitude on line 5: 81.649445
>

如果您想保留单一模式方法，我们可以将这两个值存储在字典中：

import re

pattern = r"(lat|lng):\s+(\d+\.\d+)"

location = {}

for i, line in enumerate(open('C:\hile_text.html'), start=1):
    match = re.search(pattern, line)
    if match:
        key, value = match.group(1, 2)
        location[key] = value
        print('Found %s on line %s: %s' % (key, i, value))

print(location)

<强>输出

> python test.py
Found lat on line 4: 21.25335
Found lng on line 5: 81.649445
{'lat': '21.25335', 'lng': '81.649445'}
