NameError:没有定义“随机”的名字

Question

options = [ "Choice 1: 1-9", "Choice 2: 10- 100",  ]
button = buttonbox ( msg = "Choose your range of numbers", title = "Select number range", choices = options)

if button == "Choice 1: 1-9":
 from random import randint
rn1 = randint(30,50)
from random import randint
rn2 = randint(30,50)

options = [ "Close"]
buttonbox ( msg = "%s X %s = ___" % (rn1, rn2), title = "Select number range", choices = options)
if button == "Choice 2: 10- 100":
 from random import randint
rn2 = randint (10,100)
from random import randint
rn2 = randint (10,100)
options = [ "Close"]
buttonbox ( msg = "%s X %s = ___" % (rn1, rn2), title = "Select number range", choices = options)

这是我的代码，当我尝试运行第二个选项时，它表示NameError: name 'randint' is not defined，尽管代码与第一个选项完全相同，但是数字不同。

有什么建议吗？

Answer 1

只导入一次，在文件的顶部。将from random import randint放在程序的顶部，并在所有其他地方删除它。我想这就是你想要的：

from random import randint

options = ["Choice 1: 1-9", "Choice 2: 10- 100"]
button = buttonbox(msg="Choose your range of numbers", title="Select number range", choices=options)

if button == options[0]:
    rn1 = randint(30, 50)
    rn2 = randint(30, 50)

elif button == options[1]:
    rn1 = randint(10, 100)
    rn2 = randint(10, 100)

options = ["Close"]
buttonbox (msg="%s X %s = ___" % (rn1, rn2), title="Select number range", choices=options)

我怀疑按钮不等于“选择1: 1-9”。它可能有一些尾随的白空间或一个新的行记录器。尝试打印它以验证这一点。您可以使用条带删除这些内容。

在任何情况下，正如EdChum所提到的，不建议有条件导入。更糟糕的是，您正在导入相同的模块两行。我不确定您是否想这样做，但我建议将rn1定义放在检查中。
