can't multiply sequence by non-int of type 'str' Dont understand

Question

yen = 0.0067
bsp = 1.35
usd = 0.65
ero = 0.85

if choice == \"2\":
    Current_Currency = input(\"What currency do you want to exchange: Japenese Yen if so please type y         


        

Answer 1

The line

Current_Currency = input("What currency do you want to exchange: Japenese Yen if so please type yen // British Sterling Pound please type bsp // US Dollers please Type usd // Euro please type ero.")

will throw an error if an unknown variable is entered, and Current_Currency will be set to the value of the variable name provided by the user, so the line

if Current_Currency == "yen":

isn't really needed.

yen = 0.0067
bsp = 1.35
usd = 0.65
ero = 0.85

Current_Currency = input("What currency do you want to exchange: Japenese Yen if so please type yen // British Sterling Pound please type bsp // US Dollers please Type usd // Euro please type ero.")
amount = input("Type amount you wish to exchange")
Future_Currency = input("What currency do you want to exchange into: Japenese Yen if so please type yen // British Sterling Pound please type bsp // US Dollers please Type usd // Euro please type ero.")
New_Amount =  Current_Currency / Future_Currency * amount
