This is not the same as extract number from a string as beautiful soup returns a beautiful soup object.

I have a local HTML file and I have used BeautifulSoup to Print the text between the pre code tags. This is my current code.

from bs4 import BeautifulSoup

f = open('/home/stats/trade_result.html', 'r')

s = f.read()

soup = BeautifulSoup(s,"lxml") pre = soup.find_all('pre') print(pre)

This is what gets printed out: 

last balance: xxxxxx (-0.07%)
buy hold: xxxxxx (-0.08%)
vs. buy hold: 0.01%
2 trades over 8 days (avg 0.25 trades/day)
win/loss: 0/1
error rate: 100.00%
]

How can I return the number (2 in this example) that is before "trades over" on the forth line down and use it as an integer later in my program?

Assuming that is always the fourth line inside the pre tag:

result = int(pre[0].text.split('\n')[3].split('trades over')[0])

Outputs:

2

  • sorry I m just a beginner - I thought this worked but it was wrong output. I get error message , line 10, in result = int(pre.split('\n')[3].split('trades over')[0]) AttributeError: 'ResultSet' object has no attribute 'split' – ethertec Mar 26 '18 at 00:54
  • I have also tried just using find instead of find all but get this error line 10, in result = int(pre.split('\n')[3].split('trades over')[0]) TypeError: 'NoneType' object is not callable – ethertec Mar 26 '18 at 00:56

  • This is my code - thanks for help from bs4 import BeautifulSoup f = open('/home/trade_result.html', 'r') s = f.read() soup = BeautifulSoup(s,"lxml") pre = soup.find_all('pre') #result = int(pre.split('\n')[3].split('trades over')[0]) old answer result = int(pre[0].split('\n')[3].split('trades over')[0]) – ethertec Mar 26 '18 at 21:11
