Question

执行以下代码

import easygui
from random import randint

Minimum = easygui.enterbox(msg = "Choose your minimum number")
Maximum = easygui.enterbox(msg = "Choose your maximum number")
operator = easygui.enterbox(  msg="which operator would you like to use? X,/,+ or - ?",title="operator")

rn1 = randint(Minimum,Maximum)
rn2 = randint(Minimum, Maximum)  

print "%s %s %s =?" %(rn1, operator, rn2)

给我这个错误

TypeError: cannot concatenate 'str' and 'int' objects

我知道这是字符串和整数之间的冲突，但我该如何修复呢？

Answer 1

enterbox返回一个字符串。在存储之前将值转换为整数。

import easygui
from random import randint

Minimum = int(easygui.enterbox(msg = "Choose your minimum number"))
Maximum = int(easygui.enterbox(msg = "Choose your maximum number"))
operator = easygui.enterbox(  msg="which operator would you like to use? X,/,+ or - ?",title="operator")

rn1 = randint(Minimum,Maximum)
rn2 = randint(Minimum, Maximum)  

print "%s %s %s =?" %(rn1, operator, rn2)

Answer 2

最小值和最大值是字符串，而不是整数，因此您无法将它们传递给randint。

虽然你应该注意例外，如果他们输入的东西不是int，你可以randint(int(Minimum), int(Maximum))，只要他们输入的数字很好，你就可以全部设定。

TypeError：无法连接＆＃39; str＆＃39;和＆＃39; int＆＃39;带有randint的对象
