Removing spaces from list items after parsing

I can not remove spaces from list items after parsing. Here is the fully working code.

from bs4 import BeautifulSoup
from selenium import webdriver
import pandas as pd
import xlwings as xw
driver = webdriver.PhantomJS()
driver.get("http://www.cbr.ru/hd_base/dv/?P1=4")
driver.find_element_by_id('UniDbQuery_FromDate').clear()
driver.find_element_by_id('UniDbQuery_FromDate').send_keys('11.12.2017')
driver.find_element_by_id('UniDbQuery_ToDate').clear()
driver.find_element_by_id('UniDbQuery_ToDate').send_keys('13.12.2017')
driver.find_element_by_id("UniDbQuery_searchbutton").click()
z=driver.page_source
driver.quit()
soup=BeautifulSoup(z)
x=[]
for tag in soup.tbody.findAll('td'):
    x.append(tag.text) 
y=x[1::2]
y
['381 970,85', '370 534,87', '374 626,19']

The following code does not remove spaces.

for i in y:
    i=i.replace(' ', '')
y
['381 970,85', '370 534,87', '374 626,19']

Another code also does not clear the spaces.

y = [x.strip(' ') for x in y]
y
['381 970,85', '370 534,87', '374 626,19']

Please help to solve this problem. But please do not give advice if you have not tried your code.

I think the problem is in the encoding. But this assumption, since I'm new to programming.

Solution

y = ['381 970,85', '370 534,87', '374 626,19']
lst2 = [e.replace(' ', '') for e in y]
print(lst2)

Your second case is almost right. However, the .strip does not remove the spaces inside the string.

In your first case, the string is assigned to i and then the result of replace is assigned to the i a bit later. Then it is thrown away. It does not get into the list.
