How to use a string as a part of a variable in python

Question

I would like to use a string as a part of the variable in a loop like this:

items = ['apple', 'tomato']
for item in items: 
    'eat_'+item = open("users/me/"+item+"/file.txt").read()

So that as an output I have 2 variables named eat_apple and eat_tomato.

Obviously, the 'eat_'+item is wrong but to just get my idea.

P.S. I saw similar posts but neither of them helped

if you mean to set x = 'eat_' and then say x+item = open("users/me/"+item+"/file.txt").read() , this doesn't help — plnnvkv

I meant as follows: item = pen("users/me/"+item+"/file.txt").read(). Then, item = 'eat_' + item — Mohammed Deifallah

No, this is wrong, because this eat_ part is added to the string itself, not the variable name — plnnvkv

Instead of assigning the value to the variable that is a string, you can instead create a dictonary and use the variable name(which is of string type) as key and store a corresponding value to it.
Try it:

items = ['apple', 'tomato']
eat_dict = dict()
for item in items: 
    eat_dict['eat_'+item] = open("users/me/"+item+"/file.txt").read()
