How to skip the "\n" in the output while using the readlines() method?-CodePudding

I want to read a notepad file by using the readlines() method.

f = open('/home/user/Desktop/my_file', 'r')
print(f.readlines())

The output is: ['Hello!\n', 'Welcome to Barbara restaurant. \n', 'Here is the menu. \n']

As you see the newlines will be mentioned in the output, too. What should I do? Note that I want to use the readlines() method.

P.S! My operating system is Linux Ubuntu and here's the link to my file.

I want to get the output below:

Hello!
Welcome to Barbara restaurant.
Here is the menu.

Update (Since you need the readlines() method)

f = open('/home/user/Desktop/my_file', 'r')
for line in f.readlines():
    print(line, end='')

Output

Hello!
Welcome to Barbara restaurant.
Here is the menu.

Original

You can read then split each line

f = open('/home/user/Desktop/my_file', 'r')
print(f.read().splitlines())

Output

['Hello!', 'Welcome to Barbara restaurant. ', 'Here is the menu. ']

A pipelined approach going trough every line once on demand. This can be more memory friendly with the downside of being a bite more complicated.

f = open('/home/user/Desktop/my_file', 'r')

lines_iter = map(str.strip, f)  # note you can only go through this once!
lines = list(lines_iter)        # optional: move everything to a list

f.close() # don't forget to close - but only AFTER using the map object

Output -

>>> print(lines)
['Hello!', 'Welcome to Barbara restaurant.', 'Here is the menu.']
>>> print("\n".join(lines))
Hello!
Welcome to Barbara restaurant.
Here is the menu.

Depending on the usage you don't need to move it into a list. But the file object needs to be accessible until the map object worked over it.
