Write a program which asks the user for a number and generates the multiplication table for
this number.

e.g. If the user enters 5, the program should display:
1 * 5 = 5
2 * 5 = 10
3 * 5 = 15
.
.
.
12 * 5 = 60

The program should use a while loop to generate the multiples.


This is what i have done so far:

CODE
n=input("enter a number ")
i = 0
mul=0.0
while i < 12:
    mul=i*n
    i=i+1
    print i," * ",n," = ",mul



here is what am getting.

CODE
>>>
enter a number 2
1  *  2  =  0
2  *  2  =  2
3  *  2  =  4
4  *  2  =  6
5  *  2  =  8
6  *  2  =  10
7  *  2  =  12
8  *  2  =  14
9  *  2  =  16
10  *  2  =  18
11  *  2  =  20
12  *  2  =  22
>>>


can anyone show me the correct way pf doing it?

Think through what you're telling the computer to do:

The user enters 5 for n.

You start out with i being 0. You set mul to i * n, or 0 * 5, which is 0. Then you add 1 to i, making it 1. You then print out i (1) * n (5) = mul (0).

Next time through the loop, i is 1. mul is i (1) * n (5) = 5. Add 1 to i, making it 2. Print i (2) * n (5) = mul (5).

And so on...

Do you see what the problem is now?

Much easier way to do this:
CODE
n = raw_input()
for i in range(12):
    print "%i * %i = %i" % (n, i, n*i)
