false
should be spelled False
(capital F
).
The intent behind currentbank-minusbank=afterbank
is unclear to me, but it is not valid code.
Question
It says that it can't assign the operator. Why doesn't this work?
print ("Welkom")
print ("Voer het huidige bedrag op uw rekening in")
currentbank = input ("huidige bedrag:€")
print ("Hoeveel wil je erafhalen")
minusbank = input ("min:€")
print ("Je hebt als je dit doet:")
afterbank = false
afterbank = currentbank - minusbank
print ("Dankjewel dat je dit programma gebruikt hebt")
"afterbank = currentbank - minusbank" has this error:
TypeError: unsupported operand type(s) for -: 'str' and 'str'
Solution
false
should be spelled False
(capital F
).
The intent behind currentbank-minusbank=afterbank
is unclear to me, but it is not valid code.
OTHER TIPS
Two things:
afterbank=false
You should spell it as False
. In Python True
and False
are spelled with capitals.
The following line also won't work (it's incorrect):
currentbank-minusbank=afterbank
I think you meant:
afterbank = currentbank - minusbank
which means you subtract minusbank
from currentbank
and you store the result in afterbank
.
You are trying to use assignment on an expression:
currentbank-minusbank=afterbank
This doesn't work; there is no name to assign to here. Perhaps you wanted to test for equality here?
currentbank - minusbank == afterbank
Now you have a valid expression, but the result (True
or False
) is ignored.
Your editor is also showing that you are using a name you didn't define; false
is seen as a name, not the value False
, so it is warning you that a NameError
will likely be raised there.
I think you wanted to show the result of the sum:
afterbank = currentbank - minusbank
print("Nu heb je", afterbank, "over")
