Why the output is like this?

Question

a=8
b=4
c=a/b
d=str(c)
print(2*d)

I know the result is 2.02.0 but I have no idea why I thought it should be 4

Answer 1

In python print(n*string) will print it n times concateneted

Answer 2

See comments in the code:

a=8
b=4
c=a/b # divide 8 / 4 = 2.0 division always creates a float
d=str(c) # convert float to string = '2.0'
print(2*d) # print 2 times '2.0' = '2.02.0'

Answer 3

I think it's python...
c=2.0 as / will give float whereas // gives int division...
Then d will be "2.0"
Then 2*d is same as "2.02.0"
