Help please? TypeError: can't multiply sequence by non-int of type 'str'

[yumiyay]

HELP please?
Im new to python. I made this code but I keep getting:

subtotal= 'shirts' * 'amount' * 0.20

TypeError: can't multiply sequence by non-int of type 'str'



the code is:



shirts="12.99"

amount=input("How many shirts would you like to purchase?")

subtotal= 'shirts' * 'amount' * 0.20

percentage= 'shirts' * 'amount' * 0.20

total= 'subtotal' - 'percentage'

When you put quotes or single quotes around the numbers or words, it reads them as a string of letters, not numbers. Remove the quotes.

shirts=12.99
 
amount=input("How many shirts would you like to purchase?")
 
subtotal= shirts * amount * 0.20
 
percentage= shirts * amount * 0.20
 
total= subtotal - percentage
 
print subtotal, percentage, total
 

So the error is telling you that you can't use a string of letters to multiply with numbers. Whenever you put quote marks around something, it looks at it like it's a string.

thank you. But i encountered another problem. doing so i get:
How many shirts would you like to purchase?6


Execution Successful!

Add a print statement at the end like in my example above.

[yumiyay]

thank you again for the help. I really appreciate it.
I did as you said, all i got back is:

print subtotal, percentage, total

^

SyntaxError: invalid syntax



here is the code i put:

shirts=12.99

amount=input("How many shirts would you like to purchase?")

subtotal= shirts * amount * 0.20

percentage= shirts * amount * 0.20

total= subtotal - percentage

print subtotal, percentage, total


My goal here is to get a total. Im trying to get the percentage to be subtracted from the subtotal to get that number. if it makes sense.

Try just one print statement and see what it says:

print subtotal

[yumiyay]

thankyou.

I tried
print subtotal

got:

SyntaxError: invalid syntax

Are you running this from IDLE or do you have it saved as a script?

[yumiyay]

Im trying them in both IDLE and Ninja

[wordone]

Wait....you're probably using a python 3.x version so you have to put parenthesis around things you want to print:

print (subtotal)

[yumiyay]

yep yep I am using python 3.x
and yep yep I have tried both with parenthesis and without.

I changed my code to this:

shirts=12.99

amount=float(input("How many shirts would you like to purchase?"))

subtotal= shirts * amount * 0.20

percentage= shirts * amount * 0.20

total= subtotal - percentage

print (total)


when I print (subtotal) I get the right answer
when I print (percentage) I also get the right answer
but now when I print (total) I get 0.0 no matter what number I input when I run it to test it.

OHHHHHHHHHHHHHHH I FIXED IT!! YAY!!
I see what I was doing wrong

I had:

subtotal= shirts * amount * 0.20
percentage= shirts * amount * 0.20

when actually suppose to be:

subtotal= shirts * amount
percentage= shirts * amount * 0.20



oh gee I feel soooo sillyyyyy.
Thank you so much for taking time to help me. I highly appreciate it.
