My list is not functioning properly because it is created as ["'carrots, 'tomatoes', 'lettuce'"] rather than ['carrots, 'tomatoes', 'lettuce']
I have a text file with 'carrots, 'tomatoes', 'lettuce' written on one line, and this is how I am writing it into my list:
veggie_list =[]
x = open('veggies.txt','r')
for item in x:
veggie_list.append(item)
Try this (Assuming you have multiple lines in your text file):
veggie_list = []
with open('veg.txt','r') as x:
for item in x:
veggie_list.extend(item.replace("'", "").split(','))
print(veggie_list)
Outputs:
['carrots', ' tomatoes', ' lettuce']
If you are only interested in the first line of your text file:
veggie_list = []
with open('veg.txt','r') as x:
veggie_list = x.read().replace("'","").split(',')
print(veggie_list)
One Liner in Python using list comprehension:
with open('veg.txt','r') as x:
print([j for i in x for j in i.replace("'","").split(',')])
EXPLANATION (For the first code):
You need to first remove the single quote marks from the line you have read ("'carrots', 'tomatoes', 'lettuce'") from the file. You can use replace() method of str object. This method returns a copy of modified string and it doesn't change the original string.
After that, you should be left with str "carrots, tomatoes, lettuce". Now, I have used split() method to divide the whole string into individual strings using "," as delimiter.
This method returns a list ['carrots', ' tomatoes', ' lettuce'].
