…我是Python新手,正在学习基础知识;目前我正在用Python学习这个计算器程序,但我在以下方面遇到了问题: 1当用户确定不再需要执行任何计算时,我想打印所有用户输入的答案。我创建了一个空列表“calc\u store”,但它还没有工作。 2我想“结束”或终止程序,如果用户无法进入其中一个确定的数学运算后,3次尝试。我不断得到关于第71行“缩进错误”的错误陈述,但我不知道为什么。 三。我是否使用适当的方法将用户输入保存到列表中?你知道吗
答案是伟大的,但解释是重要的,所以我可以学习!代码如下:
def Calculations():
Calc_store=[]
answer_count = 0
incorrect_count = 0
acknow = input("Please choose from the following math operations: +,-,*,//, **: ")
num1 = int(input("Please enter your first number: "))
if acknow == '**':
pow1 = int(input("Please enter your first number*: "))
pow2 = int(input("To what power?"))
print('{} ** {} = '.format(pow1, pow2))
print(pow1 ** pow2)
Power_1= pow2 ** pow2
Calc_store.append(Power_1)
answer_count +=1
Repeat_Calculations()
elif acknow == '+':
num2 = int(input("Please enter your second number: "))
print('{} + {} = '.format(num1, num2))
print(num1 + num2)
Addition_1= num1 + num2
Calc_store.append(Addition_1)
answer_count +=1
Repeat_Calculations()
elif acknow == '-':
num2 = int(input("Please enter your second number: "))
print('{} - {} = '.format(num1, num2))
print(num1 - num2)
Subtract_1= num1 - num2
Calc_store.append(Subtract_1)
answer_count +=1
Repeat_Calculations()
elif acknow == '*':
num2 = int(input("Please enter your second number: "))
print('{} * {} = '.format(num1, num2))
print(num1 * num2)
Multiply_1= num1 * num2
Calc_store.append(Multiply_1)
answer_count +=1
Repeat_Calculations()
elif acknow == '/':
num2 = int(input("Please enter your second number: "))
print('{} / {} = '.format(num1, num2))
print(num1 / num2)
Divide_1= num1 / num2
Calc_store.append(Divide_1)
answer_count +=1
Repeat_Calculations()
else:
print("Sorry I don't recognize that, try another operatror")
incorrect_count +=1
if incorrect_count > 2:
print("Too many incorrect answers")
Repeat_Calculations()
def Repeat_Calculations():
calculate2 = input("Do you want to calculate again? Please type Y for YES or N for NO: ")
if calculate2.upper() == 'Y':
Calculations()
elif calculate2.upper() == 'N':
# This was the piece that I couldn't get to work...can you please tell me what I'm doing wrong?
print('Bonsoir Elliot! The result of your %s calculculations were: [%s]' %(answer_count, Calc_store))
else:
Repeat_Calculations()
Calculations()
这是密码。我对您的代码所做的更改: 1既然你用的是
在这两个函数中,您需要它们是全局的或返回它们。我选择了让他们高兴。你知道吗
以列表形式保存计算。这个列表将操作转换为字符串,因为您只需要显示它们。
在3个错误的选项结束,我猜你已经做了,但我做了一些改变,使之工作。
更多解释请在评论中询问。你知道吗
