```python
import re

# define a string to search in
string = "This is a test string with 123 and some other text"

# use re.search to search for the pattern
match = re.search('.*(\d+).*', string)

# check if a match was found
if match:
    # print the first group that matches the pattern (\d+)
    print(match.group(1))
else:
    print("No match found")
```
