Question

class Calisan:
    counter = 0
    zam_orani = 0.0

    def __init__(self, isim, soyisim, maas):  # constructor
        self.isim = isim
        self.soyisim = soyisim
        self.maas = maas
        self.email = isim + soyisim + "@asd.com"



        Calisan.counter = Calisan.counter + 1

    def giveNameSurname(self):
        return self.isim + " " + self.soyisim

    def zam_yap(self):
        self.maas = self.maas + self.maas * self.zam_orani
kisi = Calisan(input("İsim:"),input("Soyad:"),input("Maaş:"))
print("CEO:",kisi.isim,kisi.soyisim,"\nMail:",kisi.email,"\nMaaş:",kisi.maas)
Hosgeldiniz = "Sisteme Hoşgeldiniz efendim,toplam çalışan sayınız {}'dir ".format(Calisan.counter)
print(Hosgeldiniz)
Calisan.zam_orani = float(input("Zam oranını giriniz:"))
kisi.zam_yap()
print("Zamlı Maaş:",kisi.maas)

为什么会出现此错误？

Traceback (most recent call last):

    kisi.zam_yap()

    self.maas = self.maas + self.maas * self.zam_orani
TypeError: can't multiply sequence by non-int of type 'float'

Answer 1

所有输入都是python中的字符串，因此您需要将其更改为float或integer。用float（input（“ Maas：”））

更改输入行的结尾

Answer 2

在Python中，您可以将序列（例如列表[]或str）乘以整数（整数）以复制序列中的元素。例如：

>>> l = 'abc'
>>> l * 3
'abcabcabc'

您不能将序列与非整数相乘，例如1.5：

>>> l = 'abc'
>>> l * 1.5
TypeError: can't multiply sequence by non-int of type 'float'

在代码中，将字符串self.maas乘以self.zam_orani，即float，即0.0。要乘以该数字，您需要将其转换为int

>>> l = 'abc'
>>> l * int(1.5)  # int(1.5) = 1
'abc'

或者，如果您打算将所有输入均设为数字（即，您想输入两个数字并得到乘积），则可以在计算之前将它们转换为浮点数，例如

>>> a = '0.5'
>>> b = '1.3'
>>> float(a) * float(b)
0.65

非'float'类型的int
