What's the problem in this code !?

Question

a = int(input(""))
i=1
res=1
print(" mutiplication table of "+a+"is:\n")
while i<10
res=a*i
print(res)
i++

Answer 1

Apart from these mentioned by hinanawi, there are 2 more bugs:
1. The i++ syntax is not available in Python.
2. a can't be concatenated with strings in this way as it is an int.

Here is a working version of your code:

Answer 2

i++ --> i+=1

Answer 3

various indentation issues and syntax errors:

unindent every line after the first
then add ":" after the "while i<10"
then indent everything after that by one

Answer 4

Lucky Luke yes i forgot, the pluses on line 4 should be commas

Answer 5
