从字符串中提取多个数字而不使用逗号

Question

I'm recently trying to use my RFID card's UID but I'd like the UID to be like 11217924711571 instead of [112, 179, 247, 115, 71] . I've tried int(re.search(r'\\d+', uid_str).group()) but it only returns 112 . Can somebody please help me?

You could try this:

old = [112, 179, 247, 115, 71]
new = ''.join(map(str, old)) # will be a str
new_int = int(new) # if you need it to be an integer, convert it
