麻烦帮忙写个python的正则匹配

Question

str = "坐标：120.29071,30.438198"
我想获得120.29071和30.438198这两个值，请问下谁能帮忙写一个
这是我写的完全不对：

    regex_str_lon = '^1.*,$'
    regex_str_lat = '^,.*'

Answer 1

import re
s = '坐标：120.29071,30.438198'
m = re.search(r'(\d+(?:\.\d+)?),(\d+(?:\.\d+)?)', s)
if m:
    longitude = m.group(1)
    latitude = m.group(2)
    print('longitude=%s, latitude=%s' % (longitude, latitude))

结果：longitude=120.29071, latitude=30.438198

Answer 2

匹配小数的正则表达式就可以了吧
import re

str = "坐标：120.29071,30.438198"
a = re.findall(r'd+.d+',str)
print(a)

Answer 3

re.findAll (r'd+.d+',str)
