Help with code

Question

Hi, im trying to write program that do following:
input(n)
print 1234....n
without using string methods
i make this code but something doesnt go as planned and i dont know what it is.
if __name__ == '__main__':
n = int(input())

answer = 0
for i in range(n+1):
x = i % 10
answer = answer * 10
answer =+ x

i =+ 1
print(answer)

as you can see i add the answer * 10 to "move the number to the left", but it looks like it does nothing

Answer 1

You could do it like this

for i in range(1,int(input())+1):
print(i,end ="")

Answer 2

# Use this instead

answer += x

i += 1

Answer 3

OMG such a small mistake :D i hate my Dyslexia thx :D

the problem was i had =+ instead of +=

Answer 4

Also it work only till input = 9 :D so now the new task begin :D
Edit: This is how it works now for numbers smaller that 1000. I just need input in range(150). :)

if __name__ == '__main__':
n = int(input())

answer = 0
for i in range(n+1):

x = i % 10000
if i < 10:
answer = answer * 10
elif 10 <= i <100:
answer = answer * 100
else:
answer = answer * 1000
answer += x

i += 1
print(answer)
