找到1到10之间整数的倒数

Question

因此，我需要编写一个程序，该程序请求一个从1到10的整数并计算其倒数。

while True:
    try:
        integer = int(input("Enter an integer between 1 to 10 "))
        parameter = integer in range(1,10)
        
        equation = 1/integer

        print(equation)
        break 

    except ValueError:
        print("not int")

Answer 1

您可以使用 assert> assert 检查数字是否在1和10范围内。此外，我认为，您不应该使用break，因为您想永远获得整数。 ：

while True:
    try:
        integer = int(input("Enter an integer between 1 to 10 "))
        parameter = integer in range(1,10)
        
        assert parameter # asserts the condition and checks if its True or False
        equation = 1/integer
        print(equation)

    except ValueError:
        print("not int")
        
    except AssertionError: # if assertion is False then an AssertionError is raised
        print("not between 1-10")

输出：

Enter an integer between 1 to 10 12
not between 1-10
Enter an integer between 1 to 10 2
0.5
Enter an integer between 1 to 10 val
not int

Answer 2

假设OP不考虑尝试/除了违反不使用任何“条件结构”的要求：

try:
    integer = int(input("Enter an integer between 1 to 10: "))
    1 / (integer in range(1, 11))
    print(1 / integer)
except (ValueError, ZeroDivisionError):
    print('Input not an integer in specified range')

Answer 3

由于布尔值是整数的事实：

>>> a = -1
>>> a = (0, a)[a in range(1, 11)]
>>> try:
...     print(1 / a)
... except ZeroDivisionError:
...     print('not in 1 to 10')
...
not in 1 to 10

因此您的问题可以如下解决：

while True:
    try:
        integer = int(input("Enter an integer between 1 to 10 "))
        integer = (0, integer)[integer in range(1, 11)]
        print(1 / integer)

    except ValueError:
        print("not int")

    except ZeroDivisionError:
        print("not between 1 to 10")

Answer 4

你真的很近！
唯一要更改的是如何格式化输出，请尝试这样的事情：

while True:
try:
    integer = int(input("Enter an integer between 1 to 10 "))
    parameter = integer in range(1, 10)

    equation = 1 / integer

    print("The reciprocal of " + str(integer) + " is 1/" + str(integer) + " or " + str(1/integer))
    break

except ValueError:
    print("Not an integer, please try again.")
