Why do i get this error, and how do i fix it?

Question

import random as r
import time

symbols = ["0", "1", " ", " "]
line = 1
counter = 0

for i in range (110):
x = r.randint (0, 3)
line. append(symbols[x])
counter +=1

for i in range (10000):
if counter % 5 == 0:
r_symbols = [r.randint (0, 117) for x in range (10)]
for i in symbols:
line[i] = symbols[r.randint (0, 3)]

print(*line)
counter += 1
time.sleep(0.01)

OUTPUT
Traceback (most recent call last):
line. append(symbols[x])
AttributeError: 'int' object has no attribute 'append'

Answer 1

#Final Code

import random as r
import time

symbols = ["0","1","",""]
line = [1]
counter = 0
u = 0

for i in range (110):
x = r.randint (0, 3)
line.append(symbols[x])
counter +=1

for i in range (10000):
if counter % 5 == 0:
r_symbols = [r.randint(0, 117) for x in range (10)]
for i in symbols:

line[x] = symbols[r.randint (0, 3)]
u += 1

print(*line)
counter += 1
time.sleep(0.01)

Answer 2

✅Changing " line = 1 " to "line = [1]" may fix your problem !!

▶️You got that error because int data type don't have any method called append !!

Answer 3

I changed "line = 1" to "line = [1]" and now i get this error message

Traceback (most recent call last):
line[i] = symbols[r.randint (0, 3)]
TypeError: list indices must be integers or slices, not str
