Basic Multiplication Calculator Error in Python

Question

I want to get the amount of a product from a string and multiply it by the product quantity, so I did

>>>trip='Standard Price:2000'
>>>price = trip.split(":")[1]
'2000'

I do the maths here

>>>price*2

But the answer I should get is '4000' not the one below:

>>>20002000

Isn't * symbol a multiplication sign? because when I checked that's the symbol don't know why I'm getting the raise to power answer. What did I miss?

• rnevius: By the way, 2000^2 == 4000000...not 20002000
• Wayne Werner: print(type(price)). type() is the best when you find variables behaving oddly.

Answer 1

Convert to int first:

int(price) * 2 # result: 4000

Then you can use mathematical operators as you know them. Otherwise you are multiplying strings:

"x" * 10 # result: "xxxxxxxxxx"

Answer 2

you need to convert to int before multiplication:

>>> int(price)*2

if you multiply string with a number it will produce string that number of times:

Demo:

>>> 'a'*4
'aaaa'
