下面这段话似乎符合你的问题：

foo = 'foo 19.29 bar'
numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0]

terms = foo.split()
converted = None

for i in terms:
    for j in numbers:
        if j in i:
            converted = i
            break

print(converted)

希望这有帮助!

您只需拆分字符串并搜索字符串中的数字

import re
text = "Someone 18.16-one-0 other"

print(''.join([i for i in text.split() if re.search(r'\d', i)]))

>>> 18.16-one-0
