How can I extract data from within the brackets of `onclick` attribute values?

Question

Is it possible to extract data from within onclick attribute values like analysis(1644983), AsianOdds(1644983) and EuropeOdds(1644983)? I just want to show one number, as all are same within this HTML code.

HTML

 析亚 欧

Python Code

from bs4 import BeautifulSoup

soup=BeautifulSoup(""" 析亚 欧""",'html.parser')

lines=soup.find_all('onclick')
for line in lines:
    print(line['analysis'])

Expected output

I tried to explain everything in the comments:

from bs4 import BeautifulSoup

html = '''
    析
    亚
    欧
    '''

soup = BeautifulSoup(html, 'html.parser')

# Find all  elements
elements = soup.find_all('a')

# Loop over all found elements
for element in elements:
    # Disregard element if it doesn't contain onclick attribute
    if 'onclick' not in element.attrs:
        continue
    # Get attribute value
    value = element['onclick']
    # Disregard wrong elements
    if not value.startswith('analysis('):
        continue
    # Extract position of opening bracket
    position = value.index('(') + 1
    # Slice string so only content inside bracket is left
    value = value[position:-1]
    # Print result
    print(value)
