Error while calculating taxes: TypeError: can't multiply sequence by non-int of type 'floa-CodePudding

I try to calculate my taxes using python, but I get:

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

Code:

price_without_taxes = driver.find_element_by_xpath("//div[@id='__next']/div/main/div/div/div/p/span").text
print('LE PRIX EST DE :'   price_without_taxes)
tps = price_without_taxes * 0.05
tvq = price_without_taxes * 0.09975

price_with_taxes = float((price_without_taxes   tps   tvq))
print("Sous-Total: "   "%1.2f" % price_with_taxes   "$\n")
print("Livraison: "   str(10)   "$\n")
print("Total: "   "%1.2f" % price_with_taxes   "$\n")

CodePudding user response：

Your variable, prices_without_taxes is a string rather than an int/float. You can not multiply text by floats. You would have to convert your string to an int/float frist: float(prices_without_taxes) * (multiple)

CodePudding user response：

price_without_taxes is a string, not a number.
In order to multiply it by float you have to convert it to a number.
python is "clever" enough to multiple string containing a number only by int, however it doesn't know how to multiply a string containing a number by float.
This should work better:

price_without_taxes = driver.find_element_by_xpath("//div[@id='__next']/div/main/div/div/div/p/span").text
print('LE PRIX EST DE :'   price_without_taxes)
#converting "price_without_taxes" from string to float object
price_without_taxes = float(price_without_taxes)
tps = price_without_taxes * 0.05
tvq = price_without_taxes * 0.09975

price_with_taxes = float((price_without_taxes   tps   tvq))
print("Sous-Total: "   "%1.2f" % price_with_taxes   "$\n")
print("Livraison: "   str(10)   "$\n")
print("Total: "   "%1.2f" % price_with_taxes   "$\n")
