How to get last items of a list in Python?
(5 answers)
Closed 10 months ago.
From the log file I need the last lines. I listed them in [-1:-7]
f_read = open("C:\logs.txt", "r")
status = f_read.readlines()[-1:-7]
print(status)
Python outputs
[]
How can I make it show strings?
[-7:-1]
it must be from lower to upper

why is python string split() not splitting
(3 answers)
Closed 6 years ago.
I'm trying to split
<team>
into just team, here is the code I'm using:
s = "<team>"
s.split(">")[1]
s
'<team>'
s.split(">")[1].split("<")[0]
s
'<team>
As you can see, it's still leaving me with
<team>
anyone know why>
str.split() function returns a list, it does not split the string in place.
You'll need to make a new variable:
s = "<team>"
t = s.split(">")[1]
t

How to check whether a file is empty or not

Is there a way to check if a text file is empty in Python WITHOUT using os ?
What I have tried so far
x = open("friends.txt")
friendsfile = x.readlines()
if friendsfile == None
But I don't think it's the correct way.
Not sure why you wouldn't use os, but I suppose if you really wanted you could open the file and get the first character.
with open('friends.txt') as friendsfile:
first = friendsfile.read(1)
if not first:
print('friendsfile is empty')
else:
#do something
