Getting rid of \n when using .readlines() [duplicate]

Question

This should do what you want (file contents in a list, by line, without \n)

with open(filename) as f:
    mylist = f.read().splitlines() 

I'd do this:

alist = [line.rstrip() for line in open('filename.txt')]

or:

with open('filename.txt') as f:
    alist = [line.rstrip() for line in f]

You can use .rstrip('\n') to only remove newlines from the end of the string:

for i in contents:
    alist.append(i.rstrip('\n'))

This leaves all other whitespace intact. If you don't care about whitespace at the start and end of your lines, then the big heavy hammer is called .strip().

However, since you are reading from a file and are pulling everything into memory anyway, better to use the str.splitlines() method; this splits one string on line separators and returns a list of lines without those separators; use this on the file.read() result and don't use file.readlines() at all:

alist = t.read().splitlines()

After opening the file, list comprehension can do this in one line:

fh=open('filename')
newlist = [line.rstrip() for line in fh.readlines()]
fh.close()

Just remember to close your file afterwards.

I used the strip function to get rid of newline character as split lines was throwing memory errors on 4 gb File.

Sample Code:

with open('C:\\aapl.csv','r') as apple:
    for apps in apple.readlines():
        print(apps.strip())
