是否有可以定期让我进行心理算术练习的软件？

1.简单明了的版本

下面的脚本将随机产生+，-，×和÷赋值。您可以（并且应该）设置脚本可以使用的最大数量以及分配之间的时间间隔。

            ]).decode("utf-8"))

    except (subprocess.CalledProcessError, ValueError):
        pass

while True:
    time.sleep(pause)
    get_assignment()

如何使用

1. 将脚本复制到一个空文件中，另存为 mindpractice.py

2. 以最大允许数目和分配之间的间隔时间（以秒为单位）作为参数运行它：

   python3 /path/to/mindpractice.py <max_number> <interval>
   

   例如

   python3 /path/to/mindpractice.py 1000 300
   

   最多可计算到的数字1000，在两次分配之间有5分钟的间隔。

3. 如果一切正常，则可以按常规方式将其添加到启动应用程序中，或者可以进行启动器的切换，稍后我可能会添加它:)

笔记

• 这种划分可能需要一些解释。您可能不希望以浮点数进行计算。因此，如果分配是除法，脚本将查找可以除以的数字，并随机选择一个。如果（主）号码原来是质数，则该分配将更改为另一种类型。

2.更多选择

一旦开始计算，您会发现除以100（例如）的数字要比乘以100的数字容易得多。

使用下面的脚本，您可以（并且应该）设置每种锻炼类型的最大数字（请参阅脚本下方的说明）。

    except (subprocess.CalledProcessError, ValueError):
        pass

while True:
    time.sleep(pause)
    get_assignment()

如何使用

• 完全像第一个脚本一样设置脚本，但是使用参数运行它（以任何顺序，脚本会将正确的参数链接到正确的项目）：

  • p: 暂停（两次作业之间的间隔，以秒为单位）
  • s: 减去（要计算的最大数）
  • a: 加（最大数量）
  • m: 乘（最大数）
  • d: 除（最大数）

  例如：

  python3 '/home/jacob/Desktop/num.py' a:10 d:100 s:10 m:10 p:300
  

  显示锻炼每五分钟，数多达10个，除瓜分图100。

3.让我们有点生气

能够看到一些统计数据

下面的版本向您显示每10次练习后的统计信息：

另外（当用于儿童时可能很有用），您可以查看最近100次错误回答的练习中出了什么问题。在一个隐藏的文件中，作业和它们的（不正确的）答案都被写成：

如何使用

使用方法几乎与选项2完全相同，但是您将拥有可用的日志文件和每10个作业后的得分。

4.终极版

下面的版本类似于选项3（包括日志文件和报告），但是具有一些附加功能：

• 添加计算平方根

  

• 使用一定范围的数字进行相加，而不是简单地设置最大值

• 添加仅运行特定计算类型的选项（例如，仅除法和乘法）。

• 记住上次运行的参数，没有参数时运行（仅第一次，必须设置参数）。如果在第一次运行时未设置任何参数，则脚本会发送一条消息：

"""
Use this script to practice head count. Some explanation might be needed:
The script can be used for the following types of calculating:

Type          argument example      explanation
-------------------------------------------------------------------------------
add           a:30-100              to add in numbers from 30-100
subtract      s:10-100              to subtract in numbers from 10-100
multiply      m:10-20               to multiply in numbers from 10-20
divide        d:200-400             to divide in numbers from 200-400
square root   r:1-1000              to find square root in numbers from 1-1000

N.B.
-------------------------------------------------------------------------------
- The argument p: (pause in seconds; break between the assignments) *must* be
  set, for example: p:300 to launch an assignment every 5 minutes
- A calculation type will only run *if* the argument is set for the
  corresponding type. An example: python3 /path/to/script p:60 s:30-60
  will run a subtract- assignment every minute.

Miscellaneous information:
-------------------------------------------------------------------------------
- On first run, arguments *must* be set. After first run, when no arguments
  are used the last set arguments will run, until the script is run with a new
  set of arguments.
- A log file of the last 100 incorrectly answered questions is kept in
  ~/.calculog
- After 10 assignments, the score of the last 10 pops up.

如何使用

• 将脚本复制到一个空文件中，再次将其保存为mindpractice.py。使用以下选项运行它（作为示例）

  必须设置：

  p:300                to set the interval between assignments to 5 minutes
  

  可选（进行选择）：

  a:30-100             to add in numbers from 30-100 (optional)
  s:10-100             to subtract in numbers from 10-100
  m:10-20              to multiply in numbers from 10-20
  d:200-400            to divide in numbers from 200-400
  r:1-1000             to find square root in numbers from 1-1000
  

• 示例命令：

  python3 '/path/to/mindpractice.py' p:300 d:10-100 s:10-30  r:300-600
  

  设置：

  p:300                to set the interval between assignments to 5 minutes
  d:10-100             to divide in numbers from 10-100
  s:10-30              to subtract in numbers from 10-30
  r:300-600            to calculate square roots from 300-600
  

  同时添加和乘法不被使用。

然后在下一次，如果脚本运行时使用：

python3 '/path/to/mindpractice.py'

它将记住上次使用的参数
