I don't understand why it works with different scenarios, but not with this one. Basically, some gentleman helped me out HERE with improving my code to scrape weather, which works perfectly. I then tried to do the same to scrape an ETH value which is in a span tag <span class="text-large2" data-currency-value="">$196.01</span>. So, I followed the same technique in the code, replaced the fields, and was hoping for it to work.
The code is here:
import requests
from BeautifulSoup import BeautifulSoup
import time
url = 'https://coinmarketcap.com/currencies/litecoin/'
def ltc():
while (True):
response = requests.get(url)
soup = BeautifulSoup(response.content)
price_now = int(soup.find("div", {"class": "col-xs-6 col-sm-8 col-md-4 text-left"}).find(
"span", {"class": "text-large2"}).getText())
print(u"LTC price is: {}{}".format(price_now))
# if less than 150
if 150 > price_now:
print('Price is Low')
# if more than 200
elif 200 < price_now:
print('Price is high')
if __name__ == "__main__":
ltc()
The output looks like this:
Traceback (most recent call last):
File "test2.py", line 24, in <module>
ltc()
File "test2.py", line 13, in ltc
"span", {"class": "text-large2"}).getText())
ValueError: invalid literal for int() with base 10: '196.01'
Then, I finally tried it this way; but from here I get false positives, but no errors. It prints whatever it wants
import requests
from bs4 import BeautifulSoup
import time
url = 'https://coinmarketcap.com/currencies/litecoin/'
def liteCoin():
while (True):
response = requests.get(url)
html = response.text
soup = BeautifulSoup(html, 'html.parser')
value = soup.find('span', {'class': 'text-large2'})
print(''.join(value.stripped_strings))
if 150 > value: # if less than 150
print('Price is Low!')
elif 200 < value: # if more than 200
print('Price is High')
else:
print('N/A')
time.sleep(5)
if __name__ == "__main__":
liteCoin()
Would the problem be that the value of the ETH has a $ sign inside the span tag? And, that way the program doesn't know what to do with string?
