Dictionary is giving \n error, how do I get rid of the \n?

Question

I have some code that randomly generates a word from the .txt file. I want this word to also print it's matching definition but it's not working

This is what I currently have

keywords = {'carrot': 'Green Vegetable.',
            'apple': 'Red or Green fruit.',
            'orange': 'Orange fruit.'}

print ("Here is your keyword")
import random
with open('keywords.txt') as f:
     a = random.choice(list(f))
     print (a)

print (keywords[a])

It successfully generates the random keyword but does not show the keyword's definition. This is the error that shows

, line 11, in <module>
    print (keywords[a])
KeyError: 'apple\n' 

The error, I believe, is suggesting that my keywords.txt file claims that the keyword includes \\n but It most certainly does not, I have not typed \\n anywhere in my code or my .txt file.

Answer 1

Well this is probably because of whitespace characters, like \\n or just your regular old space. You can remove them by random.choice(list(f)).strip() .

Answer 2

Lines from file contain new line ( \\n ) characters.

You should strip them.

>>> 'apple\n'.rstrip()
'apple'

>>> 'apple\n'.rstrip('\r\n') # if you want strip only trailing CR and NL.
'apple'

with open('keywords.txt') as f:
    a = random.choice([line.rstrip() for line in f])
    print (a)

Answer 3

您可以使用：

a = a.replace('\n','')
