[英]TypeError: unsupported operand type(s) for <<: 'str' and 'int'
[英]TypeError: unsupported operand type(s) for -=: 'int' and 'str'
我是 Python 的新手,正在学习一些基础知识。 我想知道为什么我会收到这个错误。 代码是:
a = 0
x = int(input('What is your first number? '))
y = int(input('What is your second number? '))
MATH = [x, y]
R = int(input('How many numbers do you want to use? '))
if R > 2:
R -= 1
New = input('What is the next number? ')
MATH.append(New)
counter = 0
answer = MATH[counter]
for i in MATH:
counter += 1
MATH[counter]
answer += answer
print(answer)
我得到的错误是:
`TypeError Traceback (most recent call last)
<ipython-input-12-ec570ecd992a> in <module>()
12 for i in MATH:
13 counter += 1
---> 14 answer += MATH[counter]
15 print(answer)
16
TypeError: unsupported operand type(s) for +=: 'int' and 'str'
任何和所有的帮助表示赞赏!
您忘记在此行中转换为int
类型:
New = input('What is the next number? ')
应该:
New = int(input('What is the next number? '))
我现在更新了代码检查。
x = int(input('What is your first number? '))
y = int(input('What is your second number? '))
MATH = [x, y]
R = int(input('How many numbers do you want to use? '))
if R > 2:
R -= 1
New = int(input('What is the next number? ')) #fixed line
MATH.append(New)
counter = 0
answer = MATH[counter]
for i in MATH:
counter += 1
MATH[counter]
answer += answer
