I have this line of code:
browser=webdriver.Chrome()
...
games1=[]
for x in browser.find_elements_by_xpath("//li[starts-with(#class,'icon_flag')]"):
if x.text!="":
games1.append(x.get_attribute('class'))
Then i am trying to make selenium click the elements i found :
for x in games1:
browser.find_element_by_xpath("//li[#class=x]").click()
How is it possible to get error message:
Message: no such element: Unable to locate element:
It really weird since i found the elements from the site!
You need to pass x as a variable. Right now you are passing the literal "x" value
for x in games1:
browser.find_element_by_xpath("//li[#class="+x+"]").click()

I have a nested list and I want to pull out the first element of every list of lists:
t = [
[['a',1],['b',2],['c',3]],
[['d',1],['e',2],['f',3]],
[['g',1],['h',2],['i',3]]
]
want = ['a','d','g']
I am getting the Comphrension wrong:
list = [x[0][0] for x in t]
It will work as long as you don't call your variable 'list' (call it 'new_t' or whatever) - list is a reserved word in python.

I am new to machine learning. I am trying to learn feature selection from this link. Here they have a line of code which is given below
search = GridSearchCV(pipeline, grid, scoring='neg_mean_squared_error', n_jobs=-1, cv=cv)
But whenever I try to run this code I get the error
I cannot find where to import neg_mean_squared_error from. I am not sure where I should write the function myself or not. The tutorial isn't clear on this issue.
It is just a typo.
You need
neg_mean_absolute_error
You typed
neg_mean_absolure_error
using an r instead of t

I tried to use to infix expression for div function as follows:
92 'div' 10
The following error message popped out:
Syntax error on 'div'
Perhaps you intended to use TemplateHaskell
In the Template Haskell Quotation 'div'
Those look like quotes (') and not back ticks (`) to me, which is why the compiler is confused. The infix expression uses the back ticks (left of 1 on most keyboards).

When I type > file.extension I know that the file is replaced by a empty file.
What if then I type > / ? My / partition will be erased and I'll lost everything in it?
I'm curious and wondering if someone already tried this.
