import re
data = "$iwantthis*1231  $and this*1121"
print re.findall(r'(\$.*?\d{2})', data)

Output

['$iwantthis*12', '$and this*11']

In [13]: s = '$iwantthis*1231  $and this*1121'

In [14]: re.findall(r'[$].*?[*].{2}', s)
Out[14]: ['$iwantthis*12', '$and this*11']

Here,

  • [$] matches $;
  • .*?[*] matches the shortest sequence of characters followed by *;
  • .{2} matches any two characters.
