I am trying to remove an item from a list, the code looks like:

s = []
full_c = ['0','1','2','3','4','5','6','7','8','9']

for i in range(5):
    s.append(full_c)

try:
    s[2].remove('1')
except:
    pass

print(*s,sep="\n")

Here I intend to remove the item '1' from the third row alone.

The result is:

['0', '2', '3', '4', '5', '6', '7', '8', '9']
['0', '2', '3', '4', '5', '6', '7', '8', '9']
['0', '2', '3', '4', '5', '6', '7', '8', '9']
['0', '2', '3', '4', '5', '6', '7', '8', '9']
['0', '2', '3', '4', '5', '6', '7', '8', '9']

Why the specific item is removed from every list (within the main list)? How to remove only one entry from the third row alone?

You're appending the same list five times. See linked dupe. – tzaman Jul 13 '17 at 15:40

instead of `.append(full_c)` do `.append(full_c[:])` – David Zemens Jul 13 '17 at 15:41
Thank you all. @DavidZemens, it works they way I wanted. – Vinodh Kumar Jul 13 '17 at 15:56
