[FIXED] What does % mean in a file

Issue

I am getting a '%' character when I cat the file. When I open this using sublime text or vim, this '%' character does not show up. I am using the following code to generate my json.txt file:

import json

filename = "json.txt"


with open(filename, "r+") as f:
    x = [1, 'simple', 'list']
    json.dumps(x)
    json.dump(x, f)

Solution

If you run cat and see %, as DroidX86 has said, it means that there is no a new line at the end of the file, you can avoid this problem using the following code:

import json

filename = "json.txt"

with open(filename, "r+") as f:
    x = [1, 'simple', 'list']
    print(json.dumps(x, indent=4),file=f)

Now, if you run cat, you no longer will see the % since the function print adds a new line for you.
