While loop is not producing multiplication table

Question

i = 0
d =  input("Enter the no. you want ")
while i < 11 :
    print(i * d)
    i+= 1

It is supposed to give multiplication table of d but it gives the following result for eg. '3' instead

3 

33

333

3333

33333

333333

3333333

33333333

Answer 1

The input() returns a string not an int and if you multiply a string in Python with an integer num, then you will get a string repeated num times. For example,

s = "stack"
print(s * 3) # Returns "stackstackstack"

You need to use int() constructor to cast the input from str to int.

d =  int(input("Enter the no. you want "))

Try this:

d = int(input("Enter the no. you want "))
for i in range(1,11):
    print(i * d)

In the above code, I have replaced your while loop construct with for loop and range() to get sequence of numbers.

BONUS:

To print/display the table in a nice and better way, try the below code:

for i in range(1,11):
    print("%d X %d = %d" % (d, i, i * d))

Outputs:

Enter the no. you want 2
2 X 1 = 2
2 X 2 = 4
2 X 3 = 6
2 X 4 = 8
2 X 5 = 10
2 X 6 = 12
2 X 7 = 14
2 X 8 = 16
2 X 9 = 18
2 X 10 = 20
